What this dot point is asking
Photography is, literally, drawing with light, and Higher rewards photographers who understand and control it. This dot point covers exposure and light: how the camera measures exposure with its light meter, and how the quality, direction and colour of light - from natural and artificial sources - shape both the technical correctness and the mood of an image. White balance, which corrects for the colour of the light, sits here too.
This knowledge is tested in the question paper (both the multiple-choice section on technical knowledge and the analysis section, where lighting is a key thing to comment on) and is central to the project, where deliberate handling of light separates strong images from snapshots.
The answer
A camera measures exposure with its light meter, which reads the brightness of the scene and indicates whether the chosen aperture, shutter speed and ISO will give a correct exposure (neither too dark and underexposed, nor too bright and overexposed). The photographer reads the meter and balances the controls to expose correctly, or chooses to deviate deliberately for effect.
Beyond correct exposure, light has quality, direction and colour, and controlling these is what gives an image its mood. Quality is whether light is hard (a small or direct source, giving sharp shadows and high contrast) or soft (a large or diffused source, giving gentle shadows and low contrast). Direction - front, side, back or top - decides how form, texture and shadow are revealed. Colour is described by white balance: light sources have different colour temperatures (warm tungsten, cool shade, neutral daylight), and white balance tells the camera to render whites neutrally rather than tinted. Photographers work with natural light (the sun, sky and weather, which change through the day) and artificial light (flash, studio lights, lamps), choosing and shaping the source to suit the subject and mood.
Light metering and correct exposure
The light meter is the photographer's guide to exposure. It measures the light and shows, on a scale, whether the image will be correctly exposed for the current settings. A correctly exposed image holds detail in both the bright areas (highlights) and the dark areas (shadows). Underexposure loses shadow detail and looks muddy; overexposure "blows out" highlights to pure white with no detail. Photographers also use exposure deliberately: slight underexposure can deepen mood, and high-key (bright) or low-key (dark) exposure is a creative choice, not a fault.
The quality and direction of light
Hard light from a small or direct source (the midday sun, a bare flash) produces sharp-edged shadows and strong contrast, which can feel dramatic or harsh. Soft light from a large or diffused source (an overcast sky, a softbox, window light through net curtains) produces gentle, gradual shadows and lower contrast, which feels calm and flattering. Direction shapes the subject: front light reveals detail evenly but flattens form; side light rakes across to reveal texture and three-dimensional form; backlight creates silhouettes or a rim of light. Choosing quality and direction together is how a photographer builds mood.
Natural, artificial light and white balance
Natural light changes constantly: the warm, low, directional light of early morning and the "golden hour" differs from flat midday sun or the soft, even light of an overcast day. Artificial light - flash, continuous studio lamps, household bulbs - can be positioned and shaped at will, giving control regardless of conditions. Different sources have different colour temperatures, so white balance matters: set it to match the light (daylight, cloudy, tungsten, fluorescent presets, or a custom value) so colours render naturally, or use automatic white balance and adjust if a cast appears.
Examples in context
A landscape photographer waits for the golden hour, when low, warm, directional sunlight rakes across the land, revealing texture in the foreground and casting long, soft-edged shadows. The light meter guides the exposure to hold detail in both the bright sky and the shaded ground, perhaps with a slight underexposure to keep the warm mood. White balance is set to daylight to preserve the warm colour rather than neutralise it.
A studio portrait uses a single softbox placed to the side of the subject. The large, diffused source gives soft light that models the face gently while a touch of side direction reveals form. A reflector on the opposite side lifts the shadows so they are not too deep. White balance is set to match the studio lights, and the meter confirms a correct exposure. Every element of the light is chosen, not accepted.

Q1. What is the difference between hard light and soft light, and what causes it? [2 marks]
- What the marker wants. Hard light from a small or direct source gives sharp, high-contrast shadows; soft light from a large or diffused source gives gentle, low-contrast shadows. The size and diffusion of the source, not its brightness, determine hardness.
Q2. What does white balance do, and when does a photographer need to change it? [2 marks]
- What the marker wants. White balance corrects for the colour temperature of the light so whites appear neutral. It is changed when the light source has a colour cast (for example, warm tungsten) so colours do not come out tinted.
Q3. What is the difference between an underexposed and an overexposed image? [2 marks]
- What the marker wants. An underexposed image is too dark and loses detail in the shadows; an overexposed image is too bright and blows out the highlights to featureless white.

SQA Higher specimen2 marksA photographer shoots a portrait under indoor tungsten lighting but the image comes out with an orange colour cast. Which camera setting should they adjust, and why? (2 marks)Show worked answer →
This is a white balance question, the kind tested in the multiple-choice section and applied throughout the project. The setting to adjust is white balance. White balance tells the camera what colour temperature the light source is, so that whites appear neutral rather than tinted.
A full answer explains the cause and the fix. Tungsten (household) lighting is warm, with a low colour temperature, so under an unsuitable white balance setting it gives images an orange cast. Setting the white balance to the tungsten preset (or a custom value matched to the light) tells the camera to compensate for the warm light, restoring neutral colour. Using automatic white balance often works, but a deliberate preset gives more reliable, predictable colour.
The discriminator is naming white balance and explaining that it corrects for the colour temperature of the light source, not just "fixing the colour".
SQA Higher 20223 marksExplain how the direction and quality of light affect the mood of a photograph, with reference to hard and soft light. (3 marks)Show worked answer →
Light has direction and quality, and both shape mood. The quality of light is whether it is hard or soft. Hard light comes from a small or distant source (direct sun, a bare flash); it produces strong, sharp-edged shadows and high contrast, which can feel dramatic, harsh or tense. Soft light comes from a large or diffused source (an overcast sky, light through a curtain, a softbox); it produces gentle, gradual shadows and low contrast, which feels calm, flattering and even.
Direction matters too. Front lighting flattens and reveals detail evenly; side lighting rakes across the subject to reveal texture and form through shadow; backlighting puts the subject in silhouette or rims it with light. A full answer links a lighting choice to its effect: for example, soft side light models a face gently while showing form, whereas hard side light carves it with deep, dramatic shadow.
Three marks reward defining hard and soft light, describing the shadows and contrast each produces, and explaining the effect on mood, ideally with direction included.
