Image Analysis
Deconstructing
- or picking images apart through the use of fine detail - is an essential
part of studying the media. Media texts are largely constructed of images,
and we take our visual literacy - our ability to read and understand
these images - largely for granted. However, in Media Studies we need
to be able to explain that decoding process, and describe the steps
taken which allow us to derive meaning A from text B.
However,
deconstruction is only the first part of the process - never forget
the purpose of a text, and that your image analysis should include
a consideration of ideology, audience,
representation and genre.
Basic Deconstruction
Two processes
used during deconstruction are denotation and connotation,
key words for Media Studes, and ones that should appear in every piece
of textual analysis you write.
| Denotation
or
first
level of signification |
Identification
and definition of elements of a text on a basic, dictionary
level - this thing is red, it is a bicycle.
Denotational
readings will be common to a large number of people - the audience
of a text will all identify the object as a red bicycle (if
they know what a bicycle is...)
|
| Connotation
or
second
level of signification |
Connotation
begins when you link an object with other signs and meanings
- the bicycle might belong to a teenager and therefore suggest
adolescence. It is red, therefore it is bright and eyecatching
and might therefore connote that its owner is an extrovert.
If you once fell off a bicycle yourself and smashed your leg
up then you may associate this bicycle with negativity and pain.
Connotations
are numerous, and vary from reader to reader.

When analysing
an image, whether moving or still, we examine how the different elements,
arranged and framed in the way that they are, combine to form meaning.
Mise En Scène
This term
(which loosely means 'putting things in the picture' or 'arranging the
frame') concerns the design and arrangement of the image. Every element
of an image contributes to its meaning, and much time and thought is
devoted to mise en scène by the creators of an image. Although
an audience's attention may be focused on characters in the foreground,
they will also be looking at the background for additional clues to
meaning. For example, two characters having an argument in a softly
lit bedroom, with many pillows, pastel colours, throw rugs, and Martha
Stewart style room accessories are not seen to be as dangerously conflicting
as two characters arguing in a deserted warehouse, under a naked lightbulb,
surrounded by the jagged angles of torn-apart packing crates, with concrete,
not deep-pile carpet under their feet.
Mise-en-scène
includes costumes, props, lighting, characters (as represented by actors
or models), special effects, sound effects and anything else which is
"put into the frame". The level of a image's realism
relies heavily on mise en scène.
In film,
the term mise en scène refers to a stylistic technique, where
long takes and the continuous movement of the camera which focus on
the details of a scene are used to create meaning. This is the opposite
of montage, where meaning is created through constant cutting.
You may also encounter the term mise en shot which refers to
the movement of the camera and the size of the shot, plus additional
technical considerations such as lens type. Mise-en-scène is
the domain of the director and the designer, mise en shot is controlled
by the photographer or cinematographer.
Organisation
As well
as scrutinising the components of an image, it is vital that the whole
organisation of the shot is considered. Whenever anyone points a camera,
or lays out a page, they make gatekeeping decisions about exactly what
their audience see or don't see. In representing an idea through imagery,
they choose to highlight certain elements and play down others. The
simplest form of this process is to look through a camera viewfinder
and decide where to point it before taking your picture. The two things
that you consider, even if only for a split second, are framing
and composition.

The Scene
Composition
The composition
of an image is simply what it is made up of. An image will display a
series of objects or people, and when referring to its compostion we
look at their arrangement within the picture. Often we infer meaning
through two objects relationship with each other. Is one depicted as
larger? More central? Better lit? How much space is there surrounding
the objects?
Images
are usually composed around the 'rule of thirds'.
Apart from
arranging objects within the picture, another decision that is made
in composition is focus, or depth of field. This dictates the
depth into the picture in which objects are in clear focus. You may
becide to blur out the background, in order to place more emphasis on
central or foreground objects. or you may decide to have everything
in your picture in equal focus, for instance in a landscape shot, or
a group photo.
Framing
Framing
deciding where an image begins and ends is as vital to
the meaning of an image as composition. There are a whole variety of
camera angles which can be selected to frame a shot (see left button
bar), and often what is left out is as important as what is included.
What is beyond the picture, for instance, what could a model be looking
at, is the source of much ambiguity and enigma. We infer meaning from
the relationship between the camera and subject (a close up is intimate,
a long shot implies emotional distance or major status difference).
By framing
two objects together in the same image, we imply a connection between
them, especially if there is a physical link, perhaps through a graphic
or colour, between them. If the connection is unusual (juxtaposition),
we are forced to consider it more carefully and this may alter our reading
of the image.
By isolating
an object within the frame - for instance showing a swimmer against
an expanse of nothing but sea - we can make them seem insignificant
and lonely. Are characters surrounded by others (trapped? loved?) or
do they have space (power? insecurity?). Are they where they need to
be (centred?), or do they have a space into which they are headed?
Technical Codes:
Lighting
Lighting
is part of the mise-en-scene, and is one of the deliberate choices made
by any producer of an image. The choice is very basic:
Natural
light
or
Artificial
Light
Most photographs
you see that make part of print ads or magazine illustrations use artifical
light. Moving images commonly use artifical light too - traditionally
film stock was not sensitive enough to respond to any but the brightest
of daylight (FACT FANS: this is why Los Angeles became a centre for
film production back in the 1900s - they have approximately nine months
of sunshine in a year). However, with new digital technologies, natural
lighting is increasingly used by film-makers, although most mainstream
producers still prefer the control that artificial lighting techniques
give them.
When examining
any lighting set up, you need to consider the following:
Where is
the light coming from (front, sides or back)?
How intense
is the light, and what time of day might it be said to represent?
Most commonly,
three point lighting is used: there is a filter in PhotoShop that will
let you play around with the different effects of this. You will hear
(or read) three types of lighting referred to.
| Key |
The
main source of light on the subject, usually coming from around
45° above and either to the left or the right of the camera
|
| Fill |
This
is a soft light, which, as it name suggests, fills in the shadows,
to avoid sharp areas of contrast caused by the main light. |
| Back |
This
comes from, obviously, behind the subject, and makes it stand
out agains the background |
The important
thing to remember about lighting is that shadow is just as important.
We see patterns of light and dark - that is how our eyes create images,
and we read both light and its absence as equally significant. The whole
meaning of an image can be changed if you alter the shadows.

Things You Should Know About Lighting

Colour
Colour
is an important part of mise-en-scene in that it creates mood and atmosphere.
Whilst still photographers have always spent time connecting subject
to background through the use of colour, film-makers are increasingly
using some very stylised techniques. Peter Greenaway's The
Cook, The Thief, His Wife and Her Lover
(1989) makes gorgeous use of colour, in both the sumptuous settings
and the Gaultier-designed costumes, and the French thriller, Dobermann
(1997) presents its actors against carefully colour-co-ordinated
backgrounds for an impressively stylish nouveau noir feel.
Colour
can be created by the objects themselves being a certain colour, or
the set being "washed" in a certain colour thorugh the use
of coloured lighting, or a coloured filter on a lens.
Colours
are powerful and complex codes, and we read them according to our culture.
They can be technical or symbolic.
