Abstract Art Abstract art flourished particularly in the period between WW1 and WW2. The subject matter was irrelevant. It was the patterns and the interplay of colours that affected the viewer. Many artists still pursue this kind of imagery. Piet Mondrian, Kandinsky, Klee

Abstract Photography I would define this as photography in which the principal subject is unclear or obscured, or is photographed in such as way as to be unidentifiable, or where the subject is of no relevance to the image. It can include m any areas of macro photography, bizarre angles, use of reflections, movement blur etc. My Examples

Aesthetics The study of what art is all about - the study perhaps of what is beauty, when a painting, a sculpture, etc is defined as beautiful. To be aesthetically interesting the object must stimulate the mind, the feelings and produce a feeling of pleasure.
Noone has yet produce a generally acceptable definition of art or beauty etc.
Quote: "The term 'aesthetics' concerns our senses and our responses to an object. If something is aesthetically pleasing to you, it is 'pleasurable' and you like it. If it is aesthetically displeasing to you, it is 'displeasurable' and you don't like it. Aesthetics involves all of your senses - vision, hearing, touch, taste, and smell - and your emotions."

Analysis Examining a photograph for its obvious content and hidden meaning. You must describe a photograph in some detail, before trying to interpret it! Often the significance of an image is peculiar to you, and there is nothing wrong with that. Please read my separate page on how to criticize a photograph. Analysis
Art Art (or the creative arts) commonly refers to the act and process of making material works which, from concept to creation, hold a fidelity to the creative impulse —ie. 'art' is work distinct from creative work that is driven by necessity ie. vocation) or by any undisciplined pursuit of recreation.
As such, the term 'art' may be taken to include forms as diverse as prose writing, poetry, dance, acting, music (both performance and creation), sculpture and painting.
In common parlance, 'art' is most commonly used to refer to the visual arts —in particular painting, drawing, and sculpting. Art is a broad term, which may be interpreted in different ways, often relating to creativity, aesthetics and generation of emotion.

Notice that photography is excluded from this definition! Many critics of art feel that photography is too mechanical and now technological a process, unlike the delicate manual skills need to paint or sculpt. However the near universal appeal of photography casts doubt on this. People respond to photographs powerfully although in different ways to paintings which are often less accessible intellectually or emotionally.

Wikipedia
Art Photography A form of photography that lived in the 1850s to 1870s, led by photographers such as H.P. Robinson Oscar Rejlander and Julia M. Cameron. In their efforts to be called artists they tried to make photographs as a painter might paint - they worked in studios, to carefully planned compositions, using multiple printing techniques from several negatives to achieve their end. However, the results were rarely satisfactory! HP Robinson etc 
  Examples

 

Avant-garde Refers to those artists who are at the fore front of changes, usually seen as very advanced compared to current ways of doing things.  Work is usually very experimental, and often difficult to understand. It pushes the boundaries of what is normally accepted. Unfortunately know who are currently the avant-garde is rather difficult as their work is rarely well-known. Once it is well known, it becomes main stream! DuChamp, calling himself R Mutt, was definitely ahead of the field with his toilet photo! Marcel DuChamp
Balance Where the photography has tried to maintain equilibrium in his or her image by having similar tonal weights on either side of the photograph.  Kodak's Notes
Banal Ordinary, uninteresting, boring Most personal photos!
Beauty The study of beauty is part of Aesthetics. Some argue that there are two kinds of beauty, natural beauty and poetic beauty: the former being found in the contemplation of nature, the latter in man's conscious, creative intervention into nature through for example painting, photography, writing, music etc..
Objects proportioned according to the golden mean seem to be more attractive. Some modern research seems to confirm this, in that people whose facial features are symmetric and proportioned according the golden ratio are consistently ranked as more attractive than those whose faces are not.
However I believe that Photography is not entirely concerned with the expression of beauty and form, but also with communication of the human situation to other humans. hence the power of documentary photography and photojournalism.
Wikipedia  
Bourgeois French word for the middle class. However it is now rather rude, meaning people with steady jobs, some money who are blind to everything but their own satisfactory lifes Wikipedia
Candid Normally meaning straight, honest, in photography it means an un-posed photograph, often taken without the subjects knowledge or agreement. Richard Bram is a member of in-public.com Richard Bram

Capitalism Capitalism is a political theory of the importance of private ownership of the means of production (industry) in ensuring wealth and success for all people, with the minimum involvement of the state in controlling industry commerce and society. Money interchanges by means of profit, and wages for labour. 
Opposition to Capitalism has often led to violence from both the factory owners as well, with many strikers being murdered.
Unfortunately there will therefore always be losers and so opposition to the concept. It is in direct opposition to communism as defined by Marxism, in which the state controls everything, ostensibly on behalf of the citizen.

Wikipedia

Chiaroscuro It is defined as a bold contrast between light and dark parts of the picture. Frequently used by portrait artists who worked with their models in studio flats at the top of a building, their models were bathed in pools of light while the surroundings were virtually totally dark. Wikipedia Rembrandt self portrait
Child Pornography Probably the most difficult area to discuss. Modern concerns about paedophiles have led to highly emotional and irrational arguments about the nature of this, to the effect that the most innocuous of photographs can be thus interpreted. You should always be careful when photographing out and about. Any children present? Then ask the parents for permission to photograph them, even if they are not to be the main subject. And never attach any identifiable information to the picture.  Sally Mann, David Hamilton, Jock Sturges (I am NOT implying that their photographs are child pornography but there has been much argument over them.).
Cliché Something has been done so often that it has no interest or value. Like the group graduation photograph...yawn! Example
Codes All communication systems work through what are called codes. For it to work the codes must be commonly understood. However different societies have different codes; a thumbs up may mean "great" for us, but something totally different to another society group.
Photographs are particularly enriched with codes, though many of them are obscure and interpretation of them is very much an individual process. For semiotics, codes can represent the values of the society.
Wikipedia
Communism A political approach to society, in which all of society (i.e. the state) controls the means of production. The communists believe that the middle-class (bourgeoisie) who own the means of production exploit the working class (proletariat) by paying them mere pittance for wages. It also seeks to establish a "classless society".
Unfortunately the formation of communist states in the 1910s and afterwards, led to the formation of dictatorships, in which power was held solely by own person, and who would happily see millions of unwanted citizens (i.e. reactionaries who opposed the state, on other words the dictator) slaughtered.
Wikipedia
Composition The structure of the photography. The analysis of the photograph will reveal the use ofd such techniques such as "rule of thirds", framing, diagonals, triangles, balance of tones, S-bends to control the eye, reading from left to right, moving into open spaces, positive and negative space, etc. Some examples  Apogee Magazine
Conceptual Art Conceptual art or idea art, is art in which the ideas embodied by a piece are more central to the work than the means used to create it. It was described by the artist Sol LeWitt thus:
In conceptual art the idea or concept is the most important aspect of the work. When an artist uses a conceptual form of art, it means that all of the planning and decisions are made beforehand and the execution is a perfunctory affair. The idea becomes a machine that makes the art.
Does that mean the art can be atrocious, as long as the idea is good? Perhaps then we're all artists at heart.
Photography and Painting etc. are both in fact very much conceptual arts. You cannot  create without having an idea. 
Wikipedia 
Connotation The term 'connotation' is all the meanings beyond beyond the literal description, i.e.  is used to refer to the social, cultural and 'personal' associations (ideological, emotional etc.) of the sign. These are typically related to the interpreter's class, age, gender, ethnicity and so on. Signs are more open to interpretation in their connotations than their denotations. Connotation in other words is very personal indeed and can thus vary enormously from person to person. However the concepts of denotation and connotation are very interwoven. Very intense discussion
Construction Where the image is actually built to meet specific criteria. The content and lay-out may appear natural but isn't. Still life is an obvious example. Another is any portrait, where the subject is fully involved in the taking, or a posed group photograph. In fact any photograph can be described as "constructed" since the taker has acted deliberately, and will have taken a deliberate decision to select an image for printing. Sam Taylor-Wood
Consumerism The demand for goods is called consumerism. It is this which drives the manufacturer and retailer to continually bring out new and therefore "better" goods. Witness the massive rate of replacement of computers, now slowing down as the technology advances are insufficient to drive people to spend increasingly larger amounts of money for some mythical improvement in quality and performance. Currently the same powerful surge can be seen in the sale of digital cameras: a new model consumer digicam lasts roughly 6 months. Likewise rarity or sole possession also can drive the market to rapid price increases - owning a genuine Picasso  painting, or a Ansel Adams original print - where the ownership of a famous name brings implicit fame and hence envy.
Vital for the progress of Capitalism.

Continuous Tone When a photographer uses the full range of tone (as opposed to "hue" - colour") across the image.   Comment
Copyright The Law of copyright is very difficult. Generally all creative work is copyright UNLESS someone states otherwise. For students reproducing other people's work in an academic study for exam purposes only is legally acceptable, as long as full acknowledgement is made. Otherwise be very careful!
Any photograph you take you own the copyright. Full stop. If a newspaper wants to publish it you can charge them for that act. If they do it without permission then you can sue them.
Comment
Culture Photography is an important part in establishing an identity and hence a culture. How a photograph is taken gives much information away on that aspect. Photographs are used to establish status, cultural identity, social standing etc. 
Edward Curtis's photographs of North American Indians is a case in point as is Augustus Sanders in Germany|.

Cutting Edge Very similar to Avant-Garde, cutting edge artists are at the forefront of the latest approaches to art. Unfortunately many photographers and artists regard themselves as cutting edge - try a search on Google! - when they are not. Also disturbing or provocative images are not necessarily "cutting edge" either! This is Venture (Portrait studio)
Denotation 'Denotation' tends to be described as the definitional, 'literal', 'obvious' or 'commonsense' meaning of a sign. There are in theory no overtones or hidden meanings in it. However since everyone has a different background - age, gender, education, ethnicity, social class, experience, etc. - not everyone will read the same meaning into the sign! So denotation must imply some degree of connotation... Very intense discussion
Decisive moment Henri Cartier-Bresson, the celebrated French photographer, defined this as the point in which all the elements of the photograph came into perfect cohesion - i.e. the perfect composition. It is not necessarily the peak of a movement. Jump
Deconstruction  This is simply the picking apart of the various parts of a photograph or other image. In doing so you reject those parts which are unhelpful and then concentrate on those which give clues as to the hidden meaning within an image. The idea was introduced by Jacques Derrida in 1967. An important part of deconstruction is the contrast of opposites e.g. Spontaneous/constructed or Original/copy. It attacks the ideas that signs and symbols are neutral by looking at the hidden meanings behind them...
As a result you can argue that you can never know the real meaning behind anything! 
New York Times  Aberystwyth University
Derivative An image which is someone's near copy of a well-known photographer's image, or where the style is deliberately copied. generally there is not much additional creativity in it. Comments(U.S.)
Diagonals  A compositional elements, the use of obvious diagonals or diagonals linking obvious focal points in the image give a strong sense of action or energy to the image.
 Example of diagonals
Document A photograph can be regarded as a document to some critics because it contains information. Because of this a photographic document can inform the viewer. It can also therefore be used to misled the viewer and be used as propaganda. Unfortunately, photographs can also be misleading, in that vital evidence is cropped out that reveals a different meaning. Very common in Russian photography in the 1920s and 30s V&A Victorian Trains
Documentary  An area of photography in which the worker studies in depth some specific aspect of society or way of life. This is a classical use of photography, providing valuable evidence for historians and sociologists, as well as simply informing members of the public. In the 1930s the tradition of photographic newspapers rose to dominance with "The Illustrated London News", "Picture Post" etc.
Famous documentary photographers have included Eugene Smith, Lewis Hine etc

Editorial images A photojournalist could submit many thousands of photographs from a major mission, e.g. Iraq. Only a few will ever be used in a newspaper, and a few more used if published in a book. Selecting the wanted photographs is the editorial process. The act of selection could be seen as an act of censorship or propaganda, in that we are only allowed to see certain images and others may not be desirable for us to see, e.g our soldiers mangled by a bomb. Thus when Prince Charles marriage to Princess Diana was breaking up all the photos of them showed miserable faces and postures... Getty Images
Enigma An enigma is a puzzle, but one that cannot be easily solved. A photograph is in itself an enigma because it catches a fraction of time, has close contact with reality, yet is basically a piece of paper with marks on! The image is interpreted by our own minds, which therefore lays open to question, what are we looking at! Minor White's photos often omit detail that helps to identify place and scale and are enigmatic. Devils Slide 
Equilibrium The balance between dark tones and light tones is rather like a see-saw: many images fail because all the dark (=heavy) tones lie on one side of the picture.  Apogee Magazine
Ethics (ethical) The study of what is good - moral - behaviour and what is evil - immoral behaviour. Ethics plays an important role in photography. If you pay to take a photograph of a tramp, are you exploiting his bad luck? Should you take photographs of people whose lives are dysfunctional? Billingham  Background
Fantasy Closely connected with Science Fiction and Fantasy, fantasy explores impossible worlds and beings. It is rare in photography, and usually exploits digital imagery to modify the photographic content. Fontcuberta - Orogenesis
Ueslmann 
Fine Art Usually regarded as painting and sculpture, fine art is always seen as part of the visual arts scene. There always has been a major argument about whether photography can be viewed as fine art. Disputed by many artists and art critics, but claimed by many photographers, I can't help but think that this is a meaningless question. Intellectual, manual and visual skills are prevalent, in fact prerequisite in both media.
Fine Art photography has no value outside that of its aesthetic content and should be looked upon as stand alone images, created purely for the indulgence of the viewer, and, lest we forget, the photography enthusiast.

Formalism Formalism refers to the style of criticism that focuses on artistic techniques in themselves, in separation from the work's social and historical context, in other words, how it's done is more important than what is in the image.
It is therefore, the concept that a work's artistic value is entirely determined by its form: the way it is made, its purely visual aspects and its medium. Formalism emphasizes compositional elements such as color, line, shape and texture rather than context and content. Formalism dominated modern art from the late 1800s through the 1960s. 
You can therefore argue that Group f64 were Formalist in their approach to and style of photography.
Example (Last year in Marienbad) 
Feminism Feminism largely focuses on limiting or eradicating gender inequality and promoting women's rights, interests, and issues in society. As a result the strength of the photographic image has lent itself particularly strongly to feminist photographers, who own a massive number of websites on that theme.  Barbara Kruger

Frame Refers to the edge of the actual photo. Outside the frame, nothing is known, except in a limited way through related images moving on, or by deduction from the contents. This the picture is a "fragment" its juxtaposition unknown and this leads to the enigma in all photos. Hence photos are themselves "surreal" being abstracted from the present moment, acquiring a primary meaning apart from that moment and being capable of being reproduce ad infinitum. Paul Hill
Framing within the photograph Here the subject is framed e.g. a castle from between the branches of a tree, a face looking out through partially drawn curtains. This is done to focus attention on the main subject. Can become a cliché if overdone, i.e. too many photos in the set contain frames. Photonhead.com

Gaze, The Looking is not indifferent. There can never be any question of 'just looking'.
Victor Burgin (1982c, 188)
When anyone looks at an image there is the question of what exactly does the viewer see - and think. In a simplistic way, a heterosexual man will almost certainly "gaze" at a photograph of a woman in quite a different way to a heterosexual woman. You can ring the changes yourself. Furthermore the nature of the woman in the image will also control the internal often unspoken response of the viewer.
In a similar way you can question the "gaze" of the photographer - what is their motive for taking the photograph in that way? This becomes an important part of the analysis. 
You must also challenge the "gaze" of the model, if human. Why is it directed away from the camera? Why is it directed at camera - and indirectly the viewer? Is it challenging, confrontational, neutral, etc.
The Gaze (Aberystwyth University)

David Chandler (A.U.)

Gender Gender is a major issue for many photographers. Although the word photographer is neutral, it is still assumed that most "professional" photographers will be men, despite women such as Anne Geddes or Annie Lieboviz. Gender issues - feminism, transsexuality, gay and lesbianism - often a major theme in photography normally from people who are themselves actively involved in those scenarios. A difficult website 
Golden Mean This is derived from Mathematics! It works out that the best proportions for something to look attractive are 1:1.6180 (it's actually more complicated than that...)
A simplified version of this is the so-called Rule of Thirds. Divide a photograph into exactly thirds and place your subject on the lines, or even better on the intersections.

High Key The use of predominantly light tones within an image, often to portray innocence, freshness, purity etc, and in more stereotyped images, feminine and baby attributes. See Low Key; David Bailey

Icon An iconic image is one which is taken to represent far more than the image itself. A classic example is the photo of Che Guavera, taken by an unknown Cuban photographer. Guevara became to symbolize revolution at any level or scale, especially amongst students even those who disliked his political significance.
An icon is an image, picture, or representation; it is a sign or likeness that stands for an object by signifying or representing it, or by analogy, as in semiotics; in computers an icon is a symbol on the monitor used to signify a command; by extension, icon is also used, particularly in modern popular culture, in the general sense of symbol — i.e. a name, face, picture or even a person readily recognized as having some well-known significance or embodying certain qualities.

Installation Art Art made for a specific space and exploiting certain qualities of that space, more often indoors than out. The term became widely used in the 1970s and 1980s.

Joiners Invented by David Hockney (who now disowns them!), these are images made by taking many individual ones of small parts of the scene and then pasting them together to a form a representation of the scene. They were intended to follow the movement of the eye as it collects information from the scene and integrates that to form an understanding of that scene. Unlike a single image it is far more time dependent. Wikipedia  Hockney Joiner

Modernism Modernists see photography as an imprint of nature, a tracing of reality, however crafted and shaped. Group f64 thus developed a very highly technical approach to photography to reveal detail in the most "accurate" way possible, using large format negatives, and a very precise exposure technique called the zone system.
This approach is still very popular amongst many Pictorial photographers, aiming at a literal vision of the world, especially Landscape and wild life photographers.

Naked Although nude and naked have the same objective meaning (i.e. not covered by clothing) and a common origin, they have differing subjective connotations, which partly match their differing origins ("nude" originally had a meaning of "plain, bare, unadorned" in a broader sense when introduced into English from Latin "nudus", while "naked" derives from the common early English word for "unclothed" that is has the same meaning as "nudus"). Some consider one term more appropriate than the other. Nude runs from artistic or tasteful absence of clothing by choice at one end or non-erotic, to naked, a non-artistic condition of being without clothes at the other, i.e. deliberately erotic.
Edward Weston took many photographs of nudes, supposedly artistic.
Helmut Newton on the other hand, took photographs of unashamedly naked women!

Objectify To turn someone into an object rather than a human being i.e. to deny their individuality so that they can be used. Frequently photographers are accused of this when photographing women in the nude. Ratajczyk (female photographer)
Panorama A photograph which is significantly longer than its height. Often used to emphasize sweeping landscapes, or very large groups of people, especially children. Special panoramic cameras are obtainable. images/panorama.jpg
Perspective The use of perspective lines leading to or nearly leading a vanishing point. These lead to strong feeling of depth in the image and leading to a 3-dimensional interpretation. The effect is strengthened by the use of wide-angle lenses, and reduced by telephoto lenses. The latter is especially important in photographing people  rather than caricaturizing them.

Pictorialism  Photography has always been a medium for the production of attractive images, especially of landscape or unusual places. Pictorialism has never gone away and never will ,despite the scathing criticism it receives from many critics.

Pornography Is the explicit display of sexual activity purely for profit and gratuitous stimulation. However nudity and sex are legitimate subjects for photography and art. It is the reason for taking such images and the method of showing that may distinguish between legitimate and illegal imagery. 
Many people feel that the reality of photography makes the subject even more immoral than if in paintings. 
One of the big issues is that of feminism and exploitation. At first seemingly clear cut, the subject is becoming blurred as more women are now producing pornography, willingly taking part in it, and watching it for pleasure.

Post-modernism The post-modernists see photography as an ever-shifting product of culture, a representation that depends, as the British critic John Tagg put it, ''on the institutions and agents which define it and set it to work.

For the critic Andy Grundberg, postmodernism is above all a condition, in which reality, authentic experience, originality, and individual artistic vision have become obsolete. As Grundberg puts it, postmodern art tells us "that things have been used up, that we are at the end of the line, that we are all prisoners of what we see."
Postmodern photography, then, is less about representation than about representations of representations, about symbols whose meaning can never truly be deciphered. Images don't reflect who we are and what we know as much as they comment on who we think we are and simultaneously shape how we understand ourselves.

Lee Friedlander  William Eggleston  Garry Winogrand
Post-structuralism Breaks the specific relationship stated between image detail and its significance. It tends to place the emphasis on the activity of the reader in a productive process of engaging with texts (i.e.here images).The subject who does this engaging does not therefore have any kind of stable identity and unified consciousness, but is him/herself structured by language. We can't stand outside language, or, in Derrida's terms, 'there is no outside of the text'. No signifier is ever free of any other signifier, all linked together in infinite semiosis. Thus no signification is ever closed. 
Whatever that means! I interpret that as meaning, we are far too complicated and implicated into our social structures that we are in fact controlled by our use of and need for language. This makes the meaningful interpretation of photographs impossible.
Structuralism and Post-Structuralism
Punctum Roland Barthes, in "Camera Lucida" invented the term as something in an image which pricks, and disturbs the viewer. It is the unexpected punctum which, in his mind, turns the good photograph into the exceptional.  Camera Lucida (Roland Barthes) studium
Realism Ever since its birth photography has always been associated with realism. Its ability to reproduce an instantaneous slice of the real world has deceived most people to regard the camera produced image as that of complete honesty. Although modern digital imagery tricks allow us to alter the "real world" to one of even complete fantasy, those abilities have always been there, they were a simply much more difficult. Assuming the genuineness of an image is therefore a dangerous road, even if the photograph is still regarded as a legitimate trace, even as a primary source of historical evidence. Cottingley Fairies   Jerry Uelsman
Reportage The use of photography in the day-to-day publication of newspapers. It is basically photo-journalism. It overlaps with documentary photography. Andrew Turner  Margaret Bourke-White
Signs A term from Semiotics. In semiotics, a sign is generally defined as, "...something that stands for something else, to someone in some capacity." but is NOT that something. 
Similarly the cross signifies Christ's death on the cross, and in that respect is also iconic. 
Wikipedia
Signified That for which the sign stands. For example Roman Catholicism; the Pope is not Roman Catholicism  - but an image of the pope can signify that Christian belief.
Christ's death on the cross is signified by a necklace with a cross. In the example see if you can work out some of the signifiers and the signified!

Structure and Structuralism Is when the arrangement of the various items within an image, i.e. the structure are more important than the central subject. This closely relates, of course, to Modernism. It assumes that there is a specific relationship between the image detail and its significance, that is, between the signs and the signified. Roland Barthes, Jacques Derrida
Style  Style is the identifying features of an artist's approach to image making. This is difficult in photography, as the very nature of the medium is not very revealing, unlike a painter who may be characterised by his/her brush strokes, desgin and composition, etc. Michael Langford "Achieving Photographic Style"
Studium Studium is similar to denotation, that is, it is the body and identifiable structure of the photograph. However, Barthes considered that although a photograph may have an admirable studium, it is not necessarily more than just good, not outstanding. What turns this good image into outstanding is the prick of the punctum, that makes you stop and think again.  Camera Lucida (Roland Barthes)  punctum
Surrealism Surrealism appeared in the 1920s as a development of Dadaism. It emphasizes the importance of the imaginative sub-conscious - remember how weird dreams can be? So many of the images look like someone's dreams. As such they also often include very strongly sexual and erotic images. The term is often used colloquially to describe unexpected juxtapositions of objects.
The best known surrealist was Salvador Dali.

Surrealism in Photography takes the idea of surrealism into photography, which some believe to be a strongly surreal medium in itself. Fantasy is becoming an important aspect of modifying images. Jerry Uelsman  Man Ray
Symbols In photography, symbols are signs which are easily recognised. For example deliberately showing the use of barb-wire in a landscape photograph is a powerful symbol of "Private - Keep Out". In that sense it is obviously another form of signifier. Wikipedia
Tension Photography is often used to report on tragedy, violence, anger hatred etc. As such the image needs to have a high element of tension in it. This can be achieved in many ways, e.g. putting the main subject too close to the edge, or even being half-cut off by the frame. Any such imbalance, if done deliberately can introduce tension into a photograph. Also using extreme emotional cues in facial expressions can do the same.  Cindy Sherman
Thirds, Rule of A useful guide in some ways, it is inaccurate in artistic terms, being only an approximation to the use of the golden mean. By deliberately avoiding the rule can introduce a distinct feeling of tension into the picture. Silverlight notes

 Trace, The Jacques Derrida introduced this term in his efforts to develop the semiotic theory of Photography. It is a minute moment of time, selected from the ceaseless flow of time by the photographer, thereby inevitably ignoring the rest. Because of the briefness of that slice the photograph often contains details unnoticed by the artist at that time often by virtue of the naturalness of what was seen, but which becomes obvious when looked at on the flat surface of a print.

Triangles   A compositional technique for linking specific elements of a scene together. By using the base as lower in the picture it also gives a significant degree of stability to it. Conversely by putting the peak at the bottom the image becomes highly unstable and hence displays tension. Architectural study
Vantage Point The position from which a photograph is taken. Interchangeable with view point. Eiffel Tower 1
Eiffel Tower 2
View Point Someone's opinion on a photograph (or something else). however it is frequently used to mean vantage point. Geoff Lawrence
