The same person in the same light, placed differently in the frame, gives two different photographs. Composition is the easiest part to learn and the most often skipped.

The rule of thirds, and when to ignore it

Divide the frame into three equal parts horizontally and vertically, then place the subject along one of those lines rather than dead centre. It is the most quoted rule in composition, and it works because it creates controlled imbalance, which keeps the viewer’s eye moving instead of parking it in the middle.

For portraits, the part that matters most is placing the eyes about a third of the way down. The eyes are where a viewer looks first in any photograph containing a person, so their position matters more than the position of the whole body.

Ignore the rule when symmetry is the point: someone centred in a doorway, in a corridor, or in a reflection on water. Perfect symmetry has its own force, but only when it is genuinely perfect — slightly off reads as a mistake rather than a choice.

The background is half the photograph

Beginners look at the subject; experienced photographers look at everything else in the frame. That is the largest difference between the two, and it requires no skill beyond habit.

The eye filters out irrelevant things when looking directly, but a camera records all of it at equal clarity. A pole growing out of the top of a head, lettering on signage, a bin, a stranger crossing behind — none of it registered at the time, and all of it dominates on review.

The habit to build is simple: before pressing the shutter, sweep your eye around all four edges of the frame looking only at the background. Most problems are solved by moving half a step sideways or lowering the camera slightly.

Headroom

The commonest compositional fault in photographs of people is too much empty space above the head. It happens because the photographer centres the face in the frame, leaving the top half as sky or ceiling while the feet are cut off.

For a half-length shot, the top of the head should sit close to the upper edge with only a small margin. For a full-length shot, there should be less space above the head than below the feet. The general principle: empty space belongs on the side the subject is facing, not above them.

If the person is looking left, leave more room on the left. A gaze creates direction, and space in that direction balances the composition; space against it makes the frame feel cramped.

Leading lines and depth

A photograph is a flat surface, so depth has to be implied rather than captured. The most effective way is with lines converging into the distance: a road, a row of columns, a railing, a line of trees, road markings. They carry the eye from the foreground into the picture.

Place the subject somewhere along the line rather than beside it. A road running away with a person standing on the verge means the line leads the eye past them and out of the frame; the same road with the person standing in it means the line ends exactly where it should.

The second way to build depth is layering: something close to the lens thrown out of focus, the subject in the middle, the background behind. A single branch or the corner of a wall in the foreground gives a photograph three planes instead of one.

Camera height changes more than you expect

Most photographs are taken at exactly the height of the person holding the camera, because that is where their hands are. It is a default rather than a decision, and changing it is the fastest way to make a picture look different.

Below eye level makes the subject taller, lengthens the legs, and puts more sky in the background — usually a cleaner background than the ground. Above eye level compresses the figure, makes the eyes read larger, and gives a softer feeling.

For children or animals, dropping to their eye level almost always beats shooting down at them. It is the simplest rule in composition and the most frequently ignored.

Never crop at a joint

When cropping a photograph of a person, avoid cutting exactly at a joint: wrist, elbow, knee, ankle. Cropping at a joint makes the limb look amputated, because the eye expects a joint to be a connection rather than an ending.

Cropping mid-segment reads far more naturally: mid-thigh, mid-forearm, mid-calf. There the eye understands that the rest continues outside the frame.

The exceptions worth remembering are the neck and the feet: cutting through the neck is never acceptable, and cutting through the feet should always be avoided in a full-length shot — missing feet leave the whole photograph feeling unfinished, even when everything else is right.
