How to Use Shape in Photography Composition
By Joe Lenton
When we think about composition, we often concentrate on where the subject sits within the frame. But composition is about much more than positioning a person, building or object. The shapes, lines, tones and proportions within the image all influence how we see it.
One useful way to explore this is to take colour away.
A monochrome photograph removes hue and saturation from the equation, leaving us much more dependent on luminosity, contrast, shape and form. This can reveal aspects of composition that might have been hidden by colour.
It also gives us a useful lesson for colour photography: good composition isn’t dependent on colour alone.
Look for shapes before you look for detail
When colour disappears, shapes and forms often become more obvious.
A dark figure against a bright background becomes a simple shape. A doorway can become a rectangle. A road can form a leading line through the frame. A group of people can become a collection of overlapping forms.
This is one reason monochrome photography can be so effective. By removing some of the visual information, we can concentrate on the underlying structure of the image.
Try looking at one of your photographs and deliberately ignoring what the subject actually is.
Instead, ask:
- What are the main shapes?
- Where are the largest areas of light and dark?
- Which lines lead the eye?
- Are the shapes balanced within the frame?
- Is there one shape that dominates?
- Do the shapes help tell the story?
You may find that you start seeing your photographs differently.
Contrast can make shapes stronger
Contrast is particularly important when working with shape.
A bright subject against a dark background will immediately attract attention. The reverse can also work, depending on the subject and the surrounding tones.
A photograph containing a narrow range of similar mid-tones may feel soft or even slightly flat. Introducing deeper blacks and brighter highlights can make the underlying shapes much more apparent.
This doesn’t mean every monochrome photograph needs extreme contrast. The important thing is to consider what the contrast is doing.
If your main subject is supposed to attract attention, the tonal structure should help rather than fight against it.
When processing a monochrome image, this can sometimes mean being more adventurous with contrast, clarity or texture than you might be with a colour photograph. But the adjustments should still serve the photograph rather than becoming an effect for its own sake.
Think about shape when you shoot
One of the easiest mistakes with black and white photography is to photograph normally and simply decide afterwards that an image would look good in monochrome.
Sometimes it will.
But if you know before pressing the shutter that you want a monochrome result, you can look for different things.
Colour may no longer be available to separate subjects or guide the eye, so you need to pay more attention to:
- Light and shadow
- Silhouettes
- Strong tonal differences
- Lines
- Repeated shapes
- Negative space
- Texture
- The relationship between foreground and background
This is particularly important with portraits.
If you’re photographing a portrait specifically for monochrome, think about how the lighting will describe the face and body rather than relying on colour or styling to provide separation.
Hollywood film noir is a useful source of inspiration here. Study how cinematographers used light, shadow and contrast to create atmosphere and direct attention through a scene.
You don’t need to recreate a film-noir portrait. Simply studying how those images are constructed can improve your understanding of monochrome composition.
Try reducing a photograph to simple shapes
Here’s a useful exercise.
Take a photograph and imagine that you have to redraw it using only a few simple shapes.
Perhaps there is a person standing on a cliff, with water below and something threatening waiting in the distance.
How would you represent the scene using only circles, rectangles and triangles?
The exercise might sound rather strange, but it forces you to think about the structure of an image rather than its subject.
You might decide that a person is a narrow vertical rectangle, the cliff is a diagonal triangle and the water is a large horizontal shape.
Suddenly you are thinking about composition at a much more fundamental level.
Simple shapes can carry meaning
Shapes can also suggest particular feelings or ideas.
A triangle can suggest direction, tension or instability. A circle can feel softer or more complete. A rectangle might suggest something solid, formal or manufactured.
These associations aren’t fixed rules, but they can influence how we respond to an image.
Think about the way artists have used shape throughout art history. Picasso’s Guernica, for example, contains numerous sharp, angular forms that contribute to the sense of movement, conflict and distress.
The point isn’t to copy another artist’s style. It is to become more aware that shapes can contribute to the emotional meaning of an image.
Don’t forget the shape of the frame
There is another type of shape that affects composition: the shape of the photograph itself.
A camera’s native aspect ratio is only one possible format. The same photograph can feel completely different when presented as a wide rectangle, a square or a more vertical frame.
This matters particularly when photographs have a specific final use.
A website banner might require a wide, letterbox-style crop. A social media post might use a square or vertical format. A printed advertisement may require another proportion altogether.
If you know the intended use before taking the photograph, you can compose for it.
Shoot for the final crop
This is particularly important for commercial photography.
If a client tells you that an image needs to work as a wide website header, don’t simply photograph normally and hope that a crop will work later.
Think about the space the final image needs.
Where will the subject sit?
How much empty space will be available?
Will there need to be room for text?
What happens if the image has to be cropped considerably?
The same applies to portraits, advertising, editorial photography and social media.
A photograph can be technically excellent but become much less effective when an important part of the composition is removed by an unexpected crop.
If you know the final format, shoot with that format in mind.
You can leave enough space around the subject to allow for the final crop, or use an in-camera crop where appropriate. Either way, you’re making a compositional decision at the time of capture rather than leaving it entirely to somebody else later.
The crop is part of the composition
Cropping isn’t simply a technical step at the end of the workflow.
Changing the aspect ratio changes the composition.
A wide crop can emphasise horizontal movement or give a subject room to move into. A vertical crop can make a person or building feel more dominant. A square frame can create a very different sense of balance.
This is why an editor or client cropping an image without understanding the original intention can sometimes produce a weaker result.
The photographer has usually made a series of decisions about where the subject sits, what is included and what is deliberately excluded.
Changing the proportions can change all of those decisions.
Think about negative space
The final aspect ratio also affects negative space.
Suppose you photograph a person looking towards the right-hand side of the frame. A wide crop may give them plenty of space to look into.
Crop that image tightly and the relationship changes.
The subject might suddenly feel cramped.
Neither version is necessarily right or wrong. The important thing is that the space around the subject contributes to the composition and should be considered deliberately.
Composition doesn’t necessarily finish when you press the shutter
There is one more stage to consider: presentation.
A photograph isn’t always viewed in isolation. It might eventually appear on a page, inside a frame, on a wall or surrounded by a mount.
The space around an image can influence how we perceive it.
A dark photograph with deep blacks, for example, can look quite different when surrounded by a black mount compared with a white one. A warm-toned photograph may feel different when presented against a warm off-white than when surrounded by a cooler white.
This is related to the wider principle of colour interaction explored by Josef Albers in Interaction of Color: our perception of a colour can change depending on the colours surrounding it.
The same general principle applies to contrast and visual relationships.
So, particularly when producing a physical print, don’t necessarily consider the job finished when the image leaves Lightroom or Photoshop.
The paper, mount, frame and surrounding space can all become part of the final presentation.
Train yourself to see composition without the subject
One of the best ways to improve composition is to stop thinking about what you are photographing for a moment.
Look at the photograph as a collection of:
- Shapes
- Lines
- Light areas
- Dark areas
- Textures
- Empty spaces
- Repeated patterns
- Contrasting forms
Ask yourself whether those elements work together.
This can be especially useful when photographing architecture, landscapes, street scenes and abstract subjects, but it can also transform the way you approach portraits and commercial photography.
Try this exercise
The next time you’re out with your camera, deliberately look for photographs that could work as simple black-and-white shapes.
Don’t worry about whether the subject is interesting.
Instead, look for:
- A strong shape against a contrasting background.
- A line that leads through the frame.
- Repeated shapes or patterns.
- A subject surrounded by useful negative space.
- A combination of light and dark shapes that creates balance.
- A scene that would still make sense if all the colour disappeared.
Then take the photograph.
Later, convert it to monochrome and see whether the composition still works.
You may discover that the photographs you thought were about colour were actually about shape all along.
Composition is more than where you put the subject
The more we study composition, the more we realise that it isn’t one single technique.
Colour can guide the eye. Lines can create movement. Contrast can establish hierarchy. Shapes can create structure. Aspect ratio can change the balance of the frame. Even the paper and mount can influence how the final image is perceived.
Monochrome photography is particularly useful for learning this because it removes one of our most powerful visual tools.
When colour disappears, we are forced to pay more attention to what remains.
And that is perhaps the most useful lesson of all: don’t just look at what you are photographing. Look at the shapes, spaces, tones and relationships that make up the photograph.
