Mumbai 26/11 - Hostage Drama plays out on Electronic Media
Yes, the security forces may have fumbled initially but to insinuate that they were a bunch of headless chickens running amok is wrong, biased, outright stupid and irresponsible as some of the international media tried hinting. The BBC World Services went to the extent of stating that the Indian Security Forces were adopting the same foolhardy approach that the Russians had taken during the Chechen separatist / terrorists’ October 2002 seizure of Moscow's Dubrovka Theater, where approximately seven hundred people were attending a performance. Russian Special Forces launched a rescue operation, but the opium-derived gas they used to disable the hostage-takers killed more than 120 hostages, as well as many of the terrorists. BBC London went the whole hog on how India has transformed from a strong emergent economy and a highly favoured foreign investment destination to a highly unsafe, terror and strife ridden country. According to initial reports from London, foreign investors are trying to withdraw their capital, lock stock and barrel. It seems that this illustrious institution of journalism forgot all about the global credit crunch, recession in Europe and the United States of America, not to mention China, India, Japan and the rest of the world. Interestingly, all of the major financial rating companies have attributed the decline in foreign investment in India to the global credit crunch and strongly feel that 26/11 – the Mumbai crisis will have a marginal effect in the long run. The foreign media seems to be much more concerned with the foreign tourists being targeted rather than the human tragedy which is unfolding. However, despite the initial reports of British and American passport holders being singled out, according to the reports filtering in, out of the 125 deaths so far, only six were that of foreign nationals while the death toll of security personnel lost has still not been released.
Paula Newton, an international security correspondent for CNN based in CNN's London bureau, came up with an equally ridiculous stance that the Indian Intelligence was as blind as a bat and had no idea how to react to situations like 26/11. She then embraced a didactic avatar educating the viewers about how the security forces should have conducted themselves and what precautions should have been taken by the Indian Security Agencies post-Islamabad Marriott Hotel bombing that occurred on 20 September 2008. She made it seem that American Security Agencies knew that 9/11 would take place and they had prevented it. She spoke of how western security concerns are addressed by their respective countries. Ironically, the security agencies in the world’s most monitored city by all sorts of cameras failed to foil the 7 July 2005 London bombings (also called the 7/7 bombings).
Al Jazeera had its own take! Mahan Abedin, an insurgency analyst, deliberated on the “sheer inequality of life in India” theory. Al Jazeera is confident that India has highly fractured, bitter and acrimonious inter-communal relations between the Muslims and the Hindus as the order of the day. Terrorism in India should be seen in this light and be regarded as home grown. Abedin stated that even people who commit heinous acts of violence occasionally make a valid point. I do concede that indeed by showing genuine concern for the plight of the millions of people who are at risk of death from poverty and by honouring the sanctity of the lives of the most destitute, we have the best chance of defeating the ideologies of hate. However, it is pertinent to point out that this alleged hatred is confined to the ultra-rightwing thinkers of both side of the divide only. India would have not emerged as a major economy if a state of peaceful coexistence and profit making had not existed.
Here I would like to point out that it is highly probable that there is a ‘foreign sectarian conspiracy’ that seeks to punish India for having sided with two major western powers in its so-called war against terror. This foreign hand has tapped on the ultra-rightwing minorities. But the Indian Terrorist/Separatist Movement (and mind you I refer to all ultra-right wing Hindus, Muslims, Sikhs and Nagas) has never ever targeted the western populace. It has at most indulged in planting bombs, low or high intensity, but never sent trained warriors to undertake ‘urbanised terror-war games’. Unfortunately, the appearance of the Grand Old Butcher of the Western Indian State of Gujarat, Narendra Modi, on the national media with his blame game did validate Al Jazeera’s claim.
The very fact that India’s war on terror, and I use the term with some reservation and it is not in the same way that Bush uses it, is summoning up resources from various federal and state authorities, also came under fire from many an international news agencies. All three major and respected broadcasting agencies used disparaging terms like ‘confused’, ‘uncoordinated’, and ‘aimlessness of the effort’. I am yet to come across any security operation conducted by any security agency anywhere in the world having invited the media as its silent partner. The media has always been used by everyone as a vehicle of their intent only. Yet it is the duty of the media to work as a watchdog of society to deliver authenticated facts and not indulge in rumour mongering. Maybe, in retrospect, the Indian authorities should have had regular press-briefings to feed the media with controlled information that could circulate in the public domain. When the press briefings did happen they were definitely uncoordinated, ill prepared and the authorities seemed to present unfriendly officers before the press. These officers were members of the actual tactical teams that had gone in. Further, these officers had not been briefed, by their superiors with public relations experience, about how much to speak or what to speak.
It was natural for all international media to turn to the Indian broadcast institutions for information. It turned out to be a case of the ‘blind leading the blind’. NDTV, one of India’s major news channel’s coverage looked immature charged with passion, devoid of any real authentic facts, pathetic use of clichés, and highly ungrammatical usage of English. We heard pidgin statements like “terrorists full of guns”, “eighth round of gunshots”, “forces will encounter here”, “two terrorist are encountered here”, “this is where fresh blood fell”, “they first come by sea” etc.
The first 12 hours were reported with the enthusiasm of an election coverage mated with readings of a cricket score card. Reporters, it is obvious were fresh and had no idea how to report an incident like what was unfolding in Mumbai. One excited young lady reported with spasmodic gestures, “These are fresh blood stains, this is exactly where somebody was killed.” Another, journalist was seen beaming with pride that she was at an undisclosable location to witness “the end game” unfold… a refrain that she is still using after a lapse of 40 hours of the hostage drama. Another journalist, obviously impressed by the phrase, adapted a new construct of ‘final push’. Then there was another journalist who could only utter “there is utter confusion here” repeatedly, as the camera kept rocking and swaying only to reveal security forces calmly lining up some hundred metres away. We also heard the refrain of “mother ship”, “delicate stage of end game”, “war zone”, “this is India’s 9/11”, “Mumbai 9/11”. And we had a barrage of questions at the press conference, with classics like “What is the condition of the dead bodies?” “What is the condition of the explosives?” and “How did the holed up terrorists defend themselves?”
However, once the initial rush of adrenaline subsided and the senior journalists descended on the scene, NDTV tried going slow on the rumour mill and projecting unconfirmed reports and conjectures as facts. Unfortunately, by then the damage had been done. International media was quoting them as Indian commentators calling the situation as fluid and highly confusing. This picture may be attributed to the fact that most Indian broadcast journalists claimed access to well placed, authoritative and informed sources and what they were narrating as facts. NDTV’s attempt to portray the human angle to this hostage drama is commendable, especially when facts are hard to come by.
On a lighter note, I couldn’t help noticing, during the early hours of the hostage drama, that when one foreign media chose to interview some Mumbai radio jockey by the name of Ms. Malini, as a witness, her accent transformed from a typical Indian to a highly affected and anglicised and nasal English…
To finally conclude, I feel that the counter-terrorist operations are being conducted in a highly professional and coordinated manner. But, the flow of information from secured governmental domain to public domain is conspicuous by its absence. The ire of the public especially those were directly affected, who had their kith and kin and loved ones unaccounted for is understandable. Here it is commendable that the dissemination of information expected from governmental agencies is actually being done by the media, no matter how sketchy at times. This is an important aspect of the outcome of this scenario which hopefully the government will review seriously. After an ordeal of 40 hours, hanging about in the hope of some news, nay any news of the ones trapped inside; unfortunately the only lists to come out were for the consumption of the foreign consulates in Mumbai. This preferential treatment speaks ill of the attitude of the governmental institutions for their own citizens. The government will have plenty to think about in the future about how to coordinate activities of various counter-insurgency, counter-terrorist, intelligence agencies and how they should work in tandem and in a coordinated fashion. Who will coordinate all these dime a dozen federal and state bodies, further how should these bodies be administered without getting caught in a quagmire of red-tapism? Maybe, the government will also want to work out its logistics as well… there are questions that come to fore… why did it take such a long time to deploy the NSG? Why were the NSG units bundled in to public buses to be ferried across the city and not deployed with the help of choppers? Are the anti-terrorist security agencies not well equipped to fight the changing face of war on terror with a change in the rules of the game? Why were no remote controlled devices used to survey the interiors of the hotel before committing the commandos to the hostile situation?
The broadcast media in the country should take a long and hard look at how they covered this situation. I feel most of the failures stemmed from the news desks and it was the editorial and research teams at the studio end which mucked up! The senior correspondents and editors could have guided reporters from falling into the trap of generalisations and sensationalisations and not project their own confusions on to the scene/scenario that was being covered. It is time that the Indian media pressurises the governmental agencies to hold regular press briefings (like the ones held in the United States and in England) through a single platform especially when multi-governmental agencies are involved. Finally, the reporters, senior and junior alike, should acquire some sort of proficiency in the language that they want to use when broadcasting. Plus these broadcast agencies and institutions should develop a style book which they can follow when in the field!

What is Gestalt psychology?
- Wilhelm Wundt is best known for establishing the first psychology lab in Liepzig, Germany, generally considered the official beginning of psychology as a field of science separate from philosophy and physiology. In addition to this accomplishment, Wundt also established the psychology journal Philosophical Studies. Structuralism was the first school of psychology and focused on breaking down mental processes into the most basic components. Researchers tried to understand the basic elements of consciousness using a method known as introspection. By today’s scientific standards, the experimental methods used to study the structures of the mind were too subjective—the use of introspection led to a lack of reliability in results.
- Other critics argue that structuralism was too concerned with internal behaviour, which is not directly observable and cannot be accurately measured.
"The fundamental "formula" of Gestalt theory might be expressed in this way,” Max Wertheimer wrote in 1924. “There are wholes, the behaviour of which is not determined by that of their individual elements, but where the part-processes are themselves determined by the intrinsic nature of the whole. It is the hope of Gestalt theory to determine the nature of such wholes.”
Have you ever noticed how a series of flashing lights often appears to be moving, such as neon signs or strands of Christmas lights? According to Gestalt psychology, this apparent movement happens because our minds fill in missing information. This belief that the whole is greater than the sum of the individual parts led to the discovery of several different phenomena that occur during perception. Based upon this belief, Gestalt psychologists developed a set of principles to explain perceptual organization, or how smaller objects are grouped to form larger ones. These principles are often referred to as the “laws of perceptual organization.”
Prägnanz (German. n. conciseness, concision, quality of being brief and comprehensive, succinctness) is the fundamental principle of gestalt perception, also referred to as the law of prägnanz, which says that we tend to order our experience in a manner that is regular, orderly, symmetric, and simple. According to Robert Sternberg (See Cognitive Psychology, 3rd Ed., Thomson Wadsworth© 2003), Gestalt psychologists attempt to discover refinements of the law of prägnanz, and this involves writing down laws which hypothetically allow us to predict the interpretation of sensation, what are often called “gestalt laws.” However, it is important to note that while Gestalt psychologists call these phenomena “laws,” a more accurate term would be “principles of perceptual organization.” These principles are much like heuristics, which are mental shortcuts for solving problems. You will find below some of the different ‘Gestalt laws’ of perceptual organization, with the law of Prägnanz being the most general law.
Law of Prägnanz
The law of Pragnanz is sometimes referred to as the law of good figure or the law of simplicity. This law holds that objects in the environment are seen in a way that makes as simple as possible. According to the law, we are innately driven to experience things in as good a gestalt as possible. “Good” can mean many things here, such a regular, orderly, simplicity, symmetry, and so on, which then refer to specific gestalt laws. For example, a set of dots outlining the shape of a star is likely to be perceived as a star, not as a set of dots. We tend to complete the figure, make it the way it “should” be, finish it. Like we somehow manage to see this as a "B"...
One very important aspect of Prägnanz is figure – ground relationship. This aspect is often elaborated as an extension of general law of Prägnanz or the law of similarity. Camouflage has a direct bearing on figure-ground relationship.
However, it was Edgar Rubin, a Danish psychologist, who was the first to systematically investigate the figure-ground phenomenon. The phenomenon captures the idea that in perceiving a visual field, some objects take a prominent role (the figures) while others recede into the background (the ground). The visual field is thus divided into these two basic parts. This effect is often used by smart logo makers, as in the three figures suggest: The logo of visitnorway.com (see figure left-above) can be viewed as both three separate elements of blue, green and navy colour. It may, however, also be viewed as a person stretching his/her arms into the air. Similarly, the logo of the Gnome Desktop Environment (see figure on the right) can be viewed as both a "G" and a footprint. Lastly, the Macintosh logo (see figure below)be viewed as a regular happy face and a happy face in profile (looking at a computer screen).
Common to these logos is that you can focus on only one "interpretation" at a time; you cannot observe both the figure and ground at the same time, as ground will become figure when shifting the focus.
It should be noted that the figure-ground is most often exemplified using the Rubin Face/Vase Illusion, named after Edgar Rubin.
According to the law of closure, things are grouped together if they seem to complete some entity. Our minds often ignore contradictory information and fills in gaps in information. In other words, the mind may experience elements it does not perceive through sensation, in order to complete a regular figure (that is, to increase regularity) i.e. the law of closure says that, if something is missing in an otherwise complete figure, we will tend to add it. A triangle, for example, with a small part of its edge missing, will still be seen as a triangle. We will “close” the gap.
In other words, the law of closure posits that we perceptually close up, or complete, objects that are not, in fact, complete. In the figure on the left the letters 'I', 'B', and 'M' although the shapes we see, in fact, are only lines of white space of differing length hovering above each other.
Similarly, we see the figure on Paul Thagard's book (see figure on the left) as forming a three-dimensional box although all we see, in fact, is 24 dissimilar red shapes (count for yourself!) on a dark red background. The figure above is the typical textbook example of the law of closure; we perceive a circle and not 8 individual circles.
The Gestalt approach can be said to be a "bottom-up" theory as it starts from the bottom (the aspects of the stimuli that influence perception) and work its way up to higher-order cognitive processes. An example of another bottom-up theory (of perception) that is well-known in the HCI community is James Gibson's theory of "direct perception" (see affordances and perception).
Law of Similarity
The law of similarity holds that things which are similar in some way appear to be grouped together. Grouping can occur in both visual and auditory stimuli. In other words, the mind groups similar elements into collective entities or totalities. This similarity might depend on relationships of form, color, size, or brightness. According to the law, we will tend to group similar items together, to see them as forming a gestalt, within a larger form. Here is a simple typographic example:
OXXXXXXXXX
XOXXXXXXXX
XXOXXXXXXX
XXXOXXXXXX
XXXXOXXXXX
XXXXXOXXXX
XXXXXXOXXX
XXXXXXXOXX
XXXXXXXXOX
XXXXXXXXXO
It is just natural for us to see the o’s as a line within a field of x’s.
According to the law of proximity, things that are near each other seem to be grouped together. In other words, spatial or temporal proximity of elements may induce the mind to perceive a collective or totality i.e., things that are close together as seen as belonging together. For example:
**************
**************
**************
You are much more likely to see three lines of close-together *’s than 14 vertical collections of 3 *’s each.
Figure, see on the right, is taken from Kazaa Media Desktop, where the law of proximity is used in designing the user interface of the popular peer-to-peer (P2P) software. As shown by the screen dump, the user can choose between P2P and web search. The group of radio buttons underneath are only associated with the P2P search and not the web search. To signal this association to the user, the vertical row of radio buttons are placed comparatively closer to the P2P-search radio button. Figure below is a typical textbook example, exemplifying how the law of proximity groups the items into 3 groups as opposed to 8 individual items.
Law of Symmetry
In the figure on the left, CSC Finland's logo is perceived as an integral whole although the two constituent geometrical shapes seem to be pointing in different directions and have differing colours.
A typical textbook example of the law of symmetry (see figure on the right-below), consists of a configuration of a number of brackets. When perceiving the configuration, we see three pairs of symmetrical brackets as opposed to 6 individual brackets, or two pairs and two singles. This happens despite what is suggested by some of the brackets immediate proximity to each other. Despite the pressure of proximity to group the brackets nearest each other together, symmetry overwhelms our perception and makes us see them as pairs of symmetrical brackets.
The law of continuity holds that points that are connected by straight or curving lines are seen in a way that follows the smoothest path. Rather than seeing separate lines and angles, lines are seen as belonging together. That is to say that the mind continues visual, auditory, and kinetic patterns.
When we can see a line, for example (as in figure on the left), as continuing through another line, rather than stopping and starting, we will do so, as in this example, which we see as composed of two lines, not as a combination of two angles.
According to this law, elements with the same moving direction are perceived as a collective or unit. The law of common fate states that when objects move in the same direction, we tend to see them as a unit. In the other words, the law of common fate is a Gestalt principle of organization holding that aspects of perceptual field that move or function in a similar manner will be perceived as a unit.
Gestalt’s law of common fate is a pretty simple concept. It is basically referring to visual directional lines within a design or layout. In a photograph, if two or more people are moving in the same direction, they have created a directional line known as the law of common fate. Together, they have a common fate or destiny. Another example of the law of common fate could include similar shapes aimed in the same direction. You might wonder why the law of common fate is of importance to artists. First of all, when two objects (whether it be shapes or organic forms) are pointed in the same direction in a layout, the directional lines become dominant in a design. So, if two or more powerful shapes are aimed at or moving in a certain direction, an artist knows to put the message at the point of destination.
Directional lines push our eyes around a page. This can be a problem every bit as much as bonus. For instance, visual collisions frustrate the viewing audience. It can cause too much tension and cause anxiety for the reader which in turn, makes the layout uninviting and too intense.
If a candid photograph of a moving car is heading to the right, the law of common fate dictates that the directional line is pointing to the right. Then again, if a candid photograph of a car is aimed towards the left and the image is part of a design, the directional line is now aimed towards the left. Therefore, if a car is headed towards the right (on an image), the image of the car should be placed towards the left-hand side of a layout, because our eyes read from left to right. This is why the law of common fate is so important. The law of common fate should not be ignored in graphic designs and advertisements. Understanding the law of common fate and how directional lines work on layouts can make all the difference in how information is read and understood.

Visual Analysis of Mediated Images
Though a visual may be analysed in many ways, of late a convention has been established to study under Six major schools of thought.
- The personal perspective deals with an emotional subjective opinion. ‘What do I think of the picture’. It’s the first response or first thought that crosses your mind on viewing the picture. It bears personal bias and prejudices.
- The historical perspective helps to determine the importance of the work based on the time period that it was created in. ‘When was this created? What was the social setup at that period of time?
- The technical perspective tries to draw a relation b/w the medium and the message. ‘What medium has been used to create the message? How has the creator expressed himself through the medium chosen.
- The ethical perspective looks at the moral and ethical responsibilities of the artist. ‘What are the moral responsibilities of the creator? Is his portrayal of the image ethical?
- The cultural perspective relates the symbols used in the image to the society. ‘What symbols has the creator used? What is the message conveyed by them?
- The critical perspective is a rational conclusion that the viewer draws from the image. It is a personal reaction though free of bias and prejudice. ‘What have I concluded after critically analyzing the picture? How different was my first opinion from the second?
Aim of Critical analysis: A producer of messages must have an understanding of the culture of the audience and use symbols that are comprehensible by them. It helps a viewer understand, interpret and appreciate art.

•The girls dark complexion.
•The light shades worn suggests summer season.
•The dark shades suggests old and shanty town.
Form
The triangle shape of the girls is a dynamic shape. its base gives a sense of stability. They are also in a group and seem like a whole unit.
'Eight' depth Cues
In trying to depict depth, there are several restrictions on the techniques that an artist can use. First, most visual texts, like paintings, drawings, illustrations, and photographs, are two-dimensional. There is no actual depth in the artwork so one must understand, at least intuitively, what information is in the environment that allow us to perceive depth. These sources of information are commonly called depth or distance cues.
The artist, in trying to paint or draw, is, therefore, limited to depth cues that (a) need no more than one eye to work, and (b) do not require a moving world. Fortunately there are a collection of such depth cues, a subset of monocular cues called pictorial cues by some authors (Goldstein, 1989).
- Interposition
- Space
- Size
- Colour
- Lighting
- Textural gradient
- Time
- Perspective
The first depth cue to be discussed here is interposition which is the partial blocking of a more distant object by a nearer object. Note how the the building is blocked by the girls. In fact, if you notice the kid behind the girls on your right is partially blocking the building too. But, it is the girls who land up blocking him too. Thus creating an illusion as to what is in the background and what is in the front. It is the interposition, overlap, that causes the sense of depth to arise. Usually the impression of depth caused by interposition alone is not very strong.
2. Space
Space is the frame in which an image is located. With a natural scene, the space depends on how close you are to the subject. Standing in an open field gives the feeling of a large amount of space and enhances the feeling of depth. If an object is close to the eyes, depth perception is limited.
Distance is related to space and helps in our perception of depth.
There is a lot of space behind the girls suggesting they are far from the buildings. The water is in the background and the wet girls suggest they had been in the water previously.
3. Size
Size can help create the illusion of the depth perception if the viewer is aware of the object’s actual size. A jumbo jet seen from a distance is a small bird sized object. If someone has no idea what the jumbo jets are, then the viewer does not react to this depth cue. Likewise, in this photograph we can guess average size (both height and size) and average size of two storied building in the backdrop we become aware of the depth (both in terms of space and distance) between the girls (foreground) and the building (background).
Size, consequently, is closely related to our ability to determine an object’s distance. Distance is related to space and helps in our perception of depth.
Size also is related to scale and mental attention. Without knowing an object’s size, we have to view it next to an object of known size in order to determine its size.
4. Colour
Correct interpretation of colour, and especially lighting cues, allows the beholder to determine the shape of objects, and thus their arrangement in space.
High contrast pictures with great differences between light and dark tones seem closer than objects with more neutral tones colour.
The exact shape and description of the shadows changes depending on the direction of the light. There are certain general rules about shadows.
Second, for a solid object sticking up the side of the object in shadow is the side away from the light but for a hole in the ground, the shadow is on the side near the light.
Shadow can play a broader role in defining depth between objects since objects that are in shadow must be farther from the light than objects that are not in shadow.
Differences in light intensities can communicate depth. Carefully crafted lighting design provides subject’s separation from background. If brightness level of the back light is slightly higher than the lights in front then this separation is more distinct. However, no backlight has been used in this photograph. Yet, the prevalence of shadows (largely in mid-space of the picture plane and the shows of the subject indicate subject’s volume and provides the viewer with reasonable illusion of depth perspective.
6.Textural gradient
Related in a sense to relative size but a depth cue in its own right is what has been termed texture gradient. Most surfaces, such as walls and roads and a field of flowers in bloom, have a texture. As the surface gets farther away from us this texture gets finer and appears smoother (Gibson, 1950).
A surface or field that recedes in depth has a texture that gets finer. That is very different from a wall where the surface is approximately the same distance from a person at all points. For example, imagine yourself standing and staring at a brick wall which, instead of receding in depth like a cobblestone road, rises up in front of you. Here the texture, in this case the brick alternating with the mortar, will have about the same roughness all over the surface and provide a clue that the surface does not recede in depth. In addition, texture may play a role in helping us determine the size of an object. Regardless of how far an object is away from us, it covers roughly the same amount of surface, and thus texture, which can help us determine the actual size of an object (Gibson, 1950).
7. Time
8. Perspective
It is a complex depth perception cue due to cultural factor which comes into play each time we try to interpret depth. However, Perspective, in the context of vision and visual perception, is the way in which objects appear to the eye based on their spatial attributes, or their dimensions and the position of the eye relative to the objects.
As objects become more distant, they appear smaller, because their angular diameter (visual angle) decreases. Perspective is also seen in the way the parallel lines of how railway tracks appear to be meeting at a distant point (the vanishing point) on the horizon. When used in this sense, the 'horizon' is always at the level of the viewer's eye. Because the Earth is round, the true horizon (the line dividing the surface and the sky) is lower than this level. The difference is imperceptibly small when standing on the surface, but noticeable from great height (a person standing on a mountain can see further than someone at ground level).
According to Evelyn Hatcher, there are three major forms of perspective which she details in her book Visual Metaphors: A Methodological Study in Visual Communication. These are as follows:
Illusionary Perspective: An illusionary perspective can be achieved through size, colour, lighting, interposition, and linear perspective. When you stand on a railroad track and look down the ties, the steel rails seem to converge into a single area, or vanishing point, in the distance. This trait of parallel lines when seen at a distance is called linear perspective. This aspect of illusionary perspective that provides the illusion of three dimensional depth in a painting or a photograph is what artists were trying to duplicate with the aid of Leonardo box and camera obscura.
Geometrical Perspective: In geometrical perspective the artist shows near figures in the lower portion of the picture and objects farther away higher in the frame on a vertical line above the near object. This type of perspective is common among traditional Japanese and Mayan artwork. Children often exhibit this type of perspective in their drawings.
Conceptual Perspective: Conceptual perspective is compositional trait that relies on a more symbolic definition of depth perception than the other types of perspective. It can be divided into two types: multi-view and social. With the multi-view perspective, a viewer can see many different sides of an object at the same time. The picture is often an X-ray, or transparent, view of the object. Near objects overlap far objects only by the outside edges or lines that make up their shapes. Pablo Picasso liked to use this type of perspective. In social perspective the most important person in a group picture, a government or corporate leader, is larger in size than other, less important people. A viewer often assumes power relationships because of social perspective. In a picture of a couple the man’s dominance over the woman often is signified by the man being nearer and larger in the frame with his hand resting on or arm wrapped around the woman’s shoulder. Over the past three decades, the feminist movement has made advertisers and others more sensitive to nonverbal negative stereotypes such as these.

Many representational visual texts give a very strong feeling of depth despite the fact that they are painted on flat surfaces that lack any depth.
In trying to depict depth, there are several restrictions on the techniques that an artist can use. First, most visual texts, like paintings, drawings, illustrations, and photographs, are two-dimensional. There is no actual depth in the artwork so one must understand, at least intuitively, what information is in the environment that allow us to perceive depth. These sources of information are commonly called depth or distance cues.
A consequence of the two-dimensional nature of painting and pictures is that we lose all the depth information that comes from the fact that we have two eyes. These binocular, or two-eye, depth cues require true depth and thus we will not discuss them in context with conventional visual texts. For example, there is the binocular depth cue called disparity. Disparity arises from the fact that our two eyes have a slightly different view of the world. To allow you to see disparity requires either real depth or two images developed as if from different positions like our eyes.
The artist, in trying to paint or draw, is, therefore, limited to depth cues that (a) need no more than one eye to work, and (b) do not require a moving world. Fortunately there are a collection of such depth cues, a subset of monocular cues called pictorial cues by some authors (Goldstein, 1989).
The first depth cue to be discussed here is interposition which is the partial blocking of a more distant object by a nearer object. Note how the the building is blocked by the girls. Infact, if you notice the kid behind the girls on your right is partially blocking the building too. But, it is the girls who land up blocking him too. Thus creating an illusion as to what is in the background and what is in the front. It is the interposition, overlap, that causes the sense of depth to arise. Usually the impression of depth caused by interposition alone is not very strong.
Notice the foreground figures of two girls with partially blocked figures of other two taking a piggy ride, which are all that are important for our present purposes. Here relative size and even relative height play little role in giving the depth order of the various figures (all the figures are roughly the same level and same size). Shadowing plays an important role in giving each of the figures their sense of three-dimensionality, but to tell who is in what position relative to another, the principle cue is interposition.
There is a lot of space behind the girls suggesting they are far from the buildings. The water is in the background and the wet girls suggest they had been in the water previously.
Movement
•The girls have moved fro near the water to the position they are in now.
Where was the picture made? What do u think was its purpose?
- The picture seems to be clicked in some Afro-American suburb.
- It could have been taken to accompany a feature article on the summer heat.
Personal Perspective
- What do I think of the visual?
- Omniphasism “All in Balance”
- Rick Williams philosopher, photographer & educator at the University of Oregon
- Theory that combines the rational and intuitive aspects of the mind.
Omniphasism was thought of by Rick Williams, a philosopher, photographer, and educator at the University of Oregon develop the theory Omniphasism. It’s a theory that attempts to combine the rational and intuitive aspects of the mind into a balanced whole. William uses 8 steps for analyzing a visual message, using his Omniphasism tech called a “personal Impact Assessment”
What is my first emotional response to the visual? Do I like it? Dislike it? How do I feel about the image?
Its a picture of teenage girls who have just played in
water. It’s pleasant to look at.
Personal Impact Assessment
“Part of the idea of going from primary words to associative words to significant words is to move away from Literal interpretation of the photo to a symbolic understanding of it." ~ Rich Williams
Personal Impact Assessment
8 Steps:
1. Take time with the image
2. List Primary Words
3. List associative words
4. Select the most important associative words
5. Pair primary and associative words
6. Relate each pair to yourself
7. Review your inner symbolism
8. Write a story
- Does the story Stimulate or Alienate?
Its an isolated moment that rests on composition.
- What is the story or message?
Some girls played in the water to beat the heat.
List Primary Words
- Visual Cues
- Objects
- Feelings
Primary words
- Group of 4 girls
- Water
- Sun
- Old buildings

Select the most important associative words
Among the associative words one word would be closest to its primary word underline or select that word. This is the most important associative word.
Choose one word out of the associative words for each primary
word.
Pair Primary and Associative words
Write the primary and most important associative word together.
- Group of 4 girls : Afro American

to mankind
Write a story
Add up all your thoughts and write a summary or a story. What is the story in the image?

summer heat by playing with some water from a fire hydrant.
Historical Perspective
- When do you think was the image made?
In the 1980’s or after.
- Is there a specific style that the image imitates?
The historical perspective helps to understand current trends in terms of their roots in technology and philosophies of the past. Where did the image come from? What was the setup at that time? What is the background of the image? these questions help us to infer meanings.
Technical Perspective
One can evaluate the production techniques. Has the producer used the technology at hand to its best in generating the message? Has it aided in delivering the message as intended effectively.
- What medium has been used?
film
- What techniques were employed?
A street shot clicked without the subject noticing it
been taken
- How was it produced?
With an SLR camera
- Is it of good quality?
yes (look at grain size, gama, composition, content, shutter speed etc.)
Ethical Perspective
This is the moral and ethical analysis of the visual. It applies to both the viewer and the producer of the visual.
Categorical Imperative
- Immanuel Kant, German philosopher from the east principality of KÖnisberg 18th Century
- Categorical (unconditional / without exception)
- “Right is Right”
- Do your duty
The right thing must be done under even the most extreme conditions. Once a rule is established for a proposed action or idea, behavior and actions must be consistently applied and always in accordance with it. One does his/ her duty.
In the ethics of the 18th-century German philosopher Immanuel Kant, founder of critical philosophy, a moral law that is unconditional or absolute for all agents, the validity or claim of which does not depend on any ulterior motive or end. “Thou shalt not steal,” for example, is categorical as distinct from the hypothetical imperatives associated with desire, such as “Do not steal if you want to be popular.” For Kant there was only one such categorical imperative, which he formulated in various ways. “Act only according to that maxim by which you can at the same time will that it should become a universal law” is a purely formal or logical statement and expresses the condition of the rationality of conduct rather than that of its morality, which is expressed in another Kantian formula: “So act as to treat humanity, whether in your own person or in another, always as an end, and never as only a means.”
Utilitarianism
- Jeremy Bentham & John Stuart Mill (British Philosophers)
- Belief: “The greatest good for the greatest number of people”
- Analysis of the consequence : Outcome must do good to most people
In ethics, a tradition stemming from the late 18th- and 19th-century English philosophers and economists Jeremy Bentham and John Stuart Mill that an action is right if it tends to promote happiness and wrong if it tends to produce the reverse of happiness—not just the happiness of the performer of the action but also that of everyone affected by it. Utilitarianism is an effort to provide an answer to the practical question “What ought a man to do?” Its answer is that he ought to act so as to produce the best consequences possible. Eg: A gruesome image must be published or printed only if it would evoke a positive reaction in maximum of the viewers.
Hedonism
Hedonism is the philosophy that pleasure is of ultimate importance, the most important pursuit. The name derives from the Greek word for "delight".
- A student of Socrates, Aristippus founded this ethical philosophy on the basis of pleasure.
- Aristippus believed that people should “act to maximize pleasure” now and not worry about the future.
- He referred to intellectual pleasure not physical.
- Pleasures of the mind
- “I Possess I am not Possessed”
- Aesthetic pleasure that we get out of a picture
Golden Mean (Finding a compromise b/w the two extreme points of an action or view.
In philosophy, especially that of Aristotle, the golden mean is the desirable middle between two extremes, one of excess and the other of deficiency.
To the Greek mentality, it was an attribute of beauty. Both ancients and moderns realized that "there is a close association in mathematics between beauty and truth". The poet John Keats, in his Ode on a Grecian Urn, put it this way:
Beauty is truth, truth beauty, that is all
Ye know on earth, and all ye need
to know.
The Greeks believed there to be three concomitants of beauty: symmetry, proportion, and harmony. This triad of principles infused their life. They were very much attuned to beauty as an object of love and something that was to be imitated and reproduced in their lives, architecture, Paideia and politics. They judged life by this mentality.
Golden Rule
- “Love your neighbor as yourself”
- Be humane do not harm others by your actions
The Golden Rule which stems from ethic of reciprocity is a fundamental moral value which "refers to the balance in an interactive system such that each party has both rights and duties, and the subordinate norm of complementarity states that one's rights are the other's obligation." In essence, it is an ethical code that states one has a right to just treatment, and a responsibility to ensure justice for others. Reciprocity is arguably the most essential basis for the modern concept of human rights, though it is not without its critics.
Many assign the imperative commandment of Golden Rule as instruction for a positive only form of reciprocity. A key element of the golden rule is that a person attempting to live by this rule treats all people, not just members of his or her in-group with consideration. The golden rule, with roots in a wide range of world cultures, is well suited to be a standard to which different cultures could appeal in resolving conflicts. Principal philosophers and religious figures have stated it in different ways.
Veil of Ignorance
John Rawls (1971) “Put the shoe on the other foot.
- All people are equal
- Eliminating all prejudice and discrimination
The original position is a hypothetical situation developed by American philosopher John Rawls as a thought experiment to replace the imagery of a savage state of nature of prior political philosophers like Thomas Hobbes. In social contract theory, persons in the state of nature agree to the provisions of a contract that defines the basic rights and duties of citizens in a civil society. In Rawls's theory, Justice as Fairness, the original position plays the role that the state of nature does in the classical social contract tradition of Thomas Hobbes, Jean-Jacques Rousseau, and John Locke.
The original position figures prominently in his book, A Theory of Justice, and it is one of the most influential ideas in twentieth-century philosophy. It has influenced a variety of thinkers from a broad spectrum of philosophical orientations. As a thought experiment, the original position is a hypothetical designed to accurately reflect what principles of justice would be manifest in a society premised on free and fair cooperation between citizens, including respect for liberty, and an interest in reciprocity.
Questions to be asked while analysing a visual from Ethical / Moral Perspective... as per Dr Demi Elliot Poynter Jamison, chair, Media Ethics & Press Policy at the University of South Florida at St. Petersberg.
1. Does the taking and displaying of the picture fit the social responsibility of the professional involved?
2. Has any ones rights been violated in taking and displaying the picture?
3. Does the display of the image meet the needs of the viewer?
4. Is the picture aesthetically appealing?
5. Does the picture choice reflect moderation?
6. Does the professional choice reflect empathy for the subjects experience?
7. Could a professional justify the choice if he/she didn’t know which of the parties (subject, shooter or viewer) he/ she would turn out to be?
8. Does the visual Image cause unjustified harm
Cultural Perspective
- Identify the Symbols used, and
- Determine their Meaning for the society as a whole.
- What is the story and the symbolism involved with the elements in the visual message?
- What do they say about current cultural values?
(It is related to the semiotic process) The story revolves around the Afro-American people in the United States of America. Historically, the country has been dominated by a settler society of religiously and ethnically diverse Whites. The heaviest burdens of racism in the country have fallen upon Native Americans, Asian Americans, African Americans, Latin Americans and some other immigrant groups and their descendants.
Major racially structured institutions include slavery, Indian reservations, segregation, residential schools (for Native Americans), and internment camps. Racial stratification has occurred in employment, housing, education and government. Formal racial discrimination was largely banned in the mid-20th century, and it came to be perceived as socially unacceptable and/or morally repugnant as well, yet racial politics remain a major phenomenon as witnessed during the 44th Presidential Elections.
Racist attitudes, or prejudice, are still held by moderate portions of the U.S population. Members of every American ethnic group have perceived racism in their dealings with other groups.
Critical Perspective
An analysis of a visual to arrive at a 'Rational', 'Objective' and 'Thoughtful' Conclusion.

How does my current view differ from the previous?
Conclusion
“Analysis is ego-driven. The main thing is that it always reveals the person making the analysis -- not really the piece itself˝ ~ David Lodge
It’s a cyclic process.
