GCSE Art & Design: Photography Skills Revision Guide

Composition

Good composition guides the viewer's eye and strengthens the message of a photograph. The rule of thirds suggests placing key elements along imaginary lines dividing the frame into a 3x3 grid rather than dead centre. Leading lines use roads, fences or shadows to draw attention toward the subject, while framing uses elements such as doorways or branches to enclose it. Negative space — large areas of plain background or sky — can isolate a subject and create a calmer, more graphic image. Experimenting with viewpoint, such as shooting from very high or very low angles, also changes the impact of an image significantly.

Camera controls

Three settings work together to control exposure: aperture, shutter speed and ISO, sometimes called the exposure triangle. Aperture (measured in f-numbers) controls how much light enters through the lens and also affects depth of field — a wide aperture (low f-number) gives a shallow depth of field, blurring the background, while a narrow aperture (high f-number) keeps more of the scene in focus. Shutter speed controls how long the sensor is exposed to light; fast speeds freeze motion, while slow speeds create blur that can suggest movement. ISO controls the sensor's sensitivity to light, with higher ISO useful in low light but at the cost of more visual noise or grain.

Lighting

Lighting direction dramatically changes mood. Front lighting evenly illuminates a subject but can look flat, side lighting emphasises texture and form through shadow, and backlighting can create silhouettes or a glowing rim of light around a subject. Natural light changes throughout the day, and photographers often favour the soft, warm light found shortly after sunrise or before sunset, sometimes called the golden hour.

Digital editing

Editing software allows adjustments such as cropping to improve composition, correcting exposure and contrast, adjusting white balance to fix colour casts, and converting images to black and white to emphasise tone and shape over colour. Edits should be purposeful and linked to your intentions rather than applied randomly — be ready to explain why you made each change.

Photographers and contextual research

Studying photographers helps you develop your own ideas. For example, Ansel Adams is known for dramatic black and white landscapes using controlled tonal range, while portrait and documentary photographers can inform how you approach people and place. Annotate how a photographer's approach to composition, lighting or subject matter has influenced your own shoots.

Common mistakes

• Taking lots of photographs without reviewing and selecting the strongest ones critically.
• Applying heavy filters that hide weak composition rather than improving the shot itself.
• Forgetting to record camera settings and decisions, making annotation difficult later.
