Depth

Updated: Jun 10, 2023

Photography is a two dimensional visual medium. Whilst this fact may seem obvious, it has a profound impact on the art and craft of the photographer. The camera renders the world onto a two dimensional plane with a clearly defined boundary. By contrast, people perceive the world in multiple dimensions: the brain reconstructs a three dimensional view of the world through our eyes, our other senses add reams of additional information (in particular touch, sound, smell, taste and temperature) and we can move our point of view (we are not fixed in what we look at by the boundary of a frame).

Consequently, before one has even started to make an image there is a gap to overcome between the image and the photographer’s perception of reality. The moment the finger presses the shutter, the picture is stripped of most of the emotional and physical input the photographer is experiencing and one of the main tasks of an artist working in a two dimensional medium is to create in the mind of the viewer the impression of more dimensionality than is actually present - in short to create depth. This article examines some of the ideas and techniques to construct depth into pictures.

‘A significant part of the journey I have been on is the elusive search for depth in my photography ’


Compositional patterns

A significant part of the journey I have been on is the elusive search for depth in my photography – depth in terms of creating the impression of three dimensions on two, depth in terms of creating and stimulating an emotional response in the viewer and depth in terms of seeing into the subject further. Compositional techniques to achieve depth are relatively well known: adjusting the relationship between objects in the foreground, the mid ground and the background and using certain compositional patterns can help to create the impression of depth.

For example one of the reasons the upright 5x4 frame using a semi wide angle lens works so well in landscape photography is that it allows the photographer plenty of real estate to organise the elements to emphasise and connect the foreground, mid ground and background. There are also a wide range of compositional patterns that achieve this with a 5x4 shape and add the characteristics of dynamic balance I mentioned in part I. The use of technical camera movements to adjust the relative proportions between front and back is often key to achieving this result (e.g. the so called looming foreground effect) as is the ability to achieve front to back sharpness through the use of tilt.

Compositional techniques can contribute to achieving depth

As an aside, although no longer using a 5x4 large format film camera I personally remain addicted to the upright 5x4 shape. I have always found a longer upright image frame such as 3:2 or taller very odd. The more traditional landscape or horizontal image shape can work but it restricts the opportunity to create depth because there is simply less real estate in the picture to organise the front to back elements and still retain picture balance. The wider the horizontal frame (such as 16x9) the smaller the number of compositional patterns that seem to work. For example 16x9 portfolios often only have one or two compositional patterns repeated - typically a v shaped movement from front left to mid right to rear left (or a similar pattern inverted).

Light

Light is the paint that a photographer applies to the canvas. What is sometimes less well understood is the role that light plays in creating depth. Firstly, the right quality of light has the ability to transform a subject, to help create an emotional response from the viewer that might otherwise not be achieved. A grey rock in shade under a blue sky, the last rays of light striking the landscape, reflecting light in ice or water, the wonderful diffused light that can bring out strong colours in a subject - all of these things are able to transform a subject and enhance the perception of depth.

Tonal relationship between darker and lighter areas of the image can help create depth

Secondly, the tonal relationship between darker and lighter areas of the image, when used well, will create a subconscious feeling of depth. Layering the image from dark to light, dark to light makes the eye move into the image slowly. It creates depth.

Deduction and exposition

Another technique the photographer can use to create depth is to pose questions and leave some aspects of the meaning of the photograph open to the interpretation of the viewer through the use of mystery, deduction or intrigue. The text or title that accompanies the can also be used to communicate the various levels of meanings that might exist in the picture. For example a cryptic title can hint at multiple levels of meaning. I will discuss seeing further into the subject in a later article.


Eliciting a response in the viewer

One definition of art is exactly that: ‘the process or product of deliberately arranging elements in a way to affect the senses or the emotions.’ The act of making art is, by this definition, to go beyond the representational - it is to

generate enough depth to tap into the emotions of a viewer and elicit a response. The techniques one develops to express oneself through art can be seen as a form of communication. It is an oft repeated adage that a picture is worth a thousand words. Developing the skills of constructing a photograph can be likened to learning a new language, or rather a new way of communicating.

Prior to the 20th century, the definition of art was subtly different -

a term used to refer to any skill, mastery or craft. I like this idea of a combined meaning in the word art; that it is both a demonstration of craft and skill and yet it is also an attempt to get the viewer to respond emotionally to a subject, to hold their attention, to say something to them that you want to say,

about a subject that might be interesting to you and potentially to them.

One definition of art is exactly that: ‘the process or product of deliberately arranging elements in a way to affect the senses or the emotions.’

As an aside, one of the big questions the artist has therefore to ask her or himself is what response to the subject and to the image do I want to create in the mind of the viewer and why? There has been a trend in art in recent years to focus on the original idea or on shocking and negative emotions as the only approach worthy of artistic appreciation. Landscape photography has suffered greatly, criticised for grand over idealised views of the world. I sometimes wonder if this expectation is just in the minds of the few who place a higher value on these ways of seeing. As a landscape photographer, I could focus on the damage being done to our environment and landscape from the hand of man, of say power stations, wind farms, pollution, litter, ugly buildings, global warming. There are plenty of examples close to me. If I made images of such subjects, if I documented this damage in ways that made people aware and angry about such things, would my art be of greater quality, value or worth than it currently is? Personally I like to celebrate how wonderful our fragile planet is, especially those places I know well, in the hope that this encourages people to take more care of them. I remain resolutely positive.


I love the British landscape and I am motivated to be there, to enjoy it and

hopefully through my representational work to stimulate a similar love for it in the viewer. Others will, no doubt, have different motivations. The point I am making is that a skilled photographer can consciously seek to influence the emotional response of the viewer. It is perhaps not a coincidence that some of the best landscape photographers I know started out or have made a living in advertising photography.

Depth is also about seeing further into the subject


Conclusion

To come back to the main point, depth is a key goal of my photography - striving to create images with more dimensionality, more meaning and more insight. Developing an understanding of how to use quality of light well in an image plays a crucial role in both the visualisation and realisation of successful images helping to accentuate the viewer’s perception of depth. Depth can also be constructed through careful composition and arrangement of the elements in the photograph. But ultimately depth is about investing time to see further into the subject and the landscape. I will discuss seeing deeper into the subject in a later series of articles.
