Camera and lens techniques

This is the technical heart of photography: how the camera and lens are controlled to make a deliberate image. It teaches the exposure triangle - aperture, shutter speed and ISO - and the creative side-effect each carries; the aperture and its counter-intuitive f-stop scale; depth of field and how aperture controls front-to-back sharpness; shutter speed and the rendering of motion; lenses and focal length, and how a converging lens forms the image on the sensor; and lighting, filters and viewpoint at the moment of capture. Mastering these controls is what turns leaving the camera on automatic into deliberate, expressive photography.

Camera and lens techniques

The camera and the exposure triangle#

StandardAQA 7206 Photography (camera and exposure)Ofqual GCE Art and Design subject content

The exposure triangle

Fig. 1The exposure triangle: aperture, shutter speed and ISO each control light and carry a creative side-effect (depth of field, motion, grain), balanced in stops to expose correctly while realising an intention.

Controlling the camera begins with exposure - the amount of light reaching the film or sensor. If too little light reaches it, the image is underexposed (too dark); if too much, overexposed (too bright); the aim is a correctly exposed image with detail across the tones you want. Exposure is governed by three interlinked controls known as the exposure triangle: aperture (the size of the lens opening), shutter speed (how long the shutter stays open) and ISO (the sensitivity of the film or sensor). Together they determine how much light is captured, and learning to balance them is the foundation of deliberate photography.

The crucial insight is that each of the three controls does two jobs. As well as contributing to exposure, each carries a creative side-effect on the look of the image: aperture controls depth of field (how much is in sharp focus front to back); shutter speed controls how motion is rendered (frozen or blurred); and ISO controls image cleanness (a clean image or one with visible grain/noise). This means setting the triangle is never just about brightness - it is about choosing the depth of field, the motion and the grain you want, and then balancing the three so the exposure still comes out right.

Because the three are interlinked, exposure is a balancing act. The controls are calibrated in 'stops', where one stop is a doubling or halving of the light. Opening the aperture one stop, slowing the shutter one stop, or raising the ISO one stop each doubles the light; closing, speeding up or lowering each halves it. So if you open the aperture one stop (letting in more light for shallow focus), you can keep the same exposure by speeding the shutter one stop, or lowering the ISO one stop - trading light between the three. This reciprocal relationship is what lets you choose creative effects while holding the exposure constant.

This is why understanding the triangle separates controlled photography from leaving the camera on automatic. On automatic, the camera picks a combination that gives a correct exposure but takes no account of what YOU want the image to look like - it might choose a small aperture (deep focus) when you wanted a blurred background, or a slow shutter (blur) when you wanted a frozen action. Shooting on manual, or a semi-automatic mode (aperture-priority or shutter-priority), lets you fix the creative variable that matters most and let the camera balance the rest, so the exposure serves your intention.

In practice, you decide which creative effect matters most for a given image and set that control first. Want a blurred background for a portrait? Set a wide aperture, then balance shutter and ISO. Want to freeze a splash? Set a fast shutter, then balance aperture and ISO. Shooting in dim light? You may have to raise the ISO and accept some grain. Reading a scene and setting the triangle to realise your creative intention - not just to expose correctly - is the core camera skill of the discipline, and everything else in this topic builds on it.

Worked example

Balancing the triangle with the reciprocal rule

A correctly exposed shot is f/8, 1/125, ISO 200. You want a blurred background, so you open the aperture two stops to f/4. How do you keep the exposure correct?

Count the light gained
Opening from f/8 to f/4 is two stops wider (f/8 to f/5.6 is one stop, f/5.6 to f/4 is another), so the aperture now lets in four times (two stops) more light.
Decide where to compensate
To hold the exposure, remove two stops of light elsewhere - either by speeding the shutter two stops or lowering the ISO two stops (or one each).
Speed the shutter two stops
From 1/125, two stops faster is 1/250 then 1/500 - so 1/500 removes exactly the two stops the wider aperture added, keeping ISO at 200.
State the new settings
The new exposure f/4, 1/500, ISO 200 lets in the same total light as f/8, 1/125, ISO 200 - but now with the shallow depth of field you wanted.

Result: Opening two stops for shallow focus is balanced by speeding the shutter two stops (1/125 to 1/500), holding the exposure while achieving the creative effect - the reciprocal logic of the triangle.

Typical mistakes

Leaving the camera on automatic, so exposure is correct but the creative effects of aperture, shutter and ISO are not controlled.
Thinking exposure is only about brightness, forgetting that each control also carries a creative side-effect.

Active revision

Photograph one subject three ways using aperture-priority, then shutter-priority, then a raised ISO in dim light; note for each which creative effect you controlled and how the camera balanced the rest.

Aperture and f-stops#

StandardAQA 7206 Photography (aperture)Ofqual GCE Art and Design subject content

The aperture (f-stop) scale

Fig. 2The standard f-stops: each step is one stop (a halving of the light). Small f-numbers are wide openings (more light, shallow depth of field); large f-numbers are narrow openings (less light, deep depth of field).

Aperture is the size of the adjustable opening inside the lens through which light passes. A wide opening lets in a lot of light; a narrow opening lets in little. Aperture is measured in f-numbers, or f-stops - f/1.4, f/2, f/2.8, f/4, f/5.6, f/8, f/11, f/16, f/22 - and the most important thing to fix in your mind is that the scale is counter-intuitive: a SMALL f-number means a WIDE opening (more light), and a LARGE f-number means a NARROW opening (less light). This is because the f-number is a ratio (the focal length divided by the opening's diameter), so a bigger number describes a smaller fraction of the lens. Confusing this is one of the commonest beginner errors.

The standard f-stops form a stop sequence: each full stop along the scale halves (or doubles) the light. Going from f/2.8 to f/4 halves the light; from f/4 to f/2.8 doubles it. The odd-looking numbers (1.4, 2, 2.8, 4, 5.6, 8, 11, 16, 22) are not random - they are (approximately) successive multiples of the square root of two, because halving the AREA of a circular opening means multiplying its diameter by that factor. You do not need the maths to use them, but you do need to know that each step is one stop, so aperture trades in stops exactly like shutter speed and ISO, which is what makes the reciprocal balance of the triangle work.

Aperture's creative side-effect is depth of field, covered fully in the next section: a wide aperture (small f-number) gives a shallow depth of field with a blurred background, while a narrow aperture (large f-number) gives a deep depth of field with everything sharp. This is why aperture is often the control a photographer sets first: they choose the depth of field they want (blurred background for a portrait, everything sharp for a landscape), which fixes the aperture, and then balance shutter and ISO around it. Aperture-priority mode exists precisely to support this way of working.

Aperture also affects a lens's practical qualities. Most lenses are sharpest a stop or two down from their widest opening (often around f/5.6-f/8) and lose a little sharpness at the very smallest apertures (f/16-f/22) due to an optical effect called diffraction - so the extreme small apertures buy deep focus at a slight cost in overall sharpness. The widest aperture a lens offers (its 'maximum aperture', for example f/1.8 or f/2.8) is a key spec: a 'fast' lens with a wide maximum aperture lets you shoot in low light and achieve very shallow focus, which is why such lenses are prized.

For your practice, get fluent with the f-stop scale until it is second nature: small number, wide opening, more light, shallow focus; large number, narrow opening, less light, deep focus. Practise choosing the aperture first for the depth of field you want, and reading how many stops apart two settings are. Because aperture links light and focus depth so directly, controlling it deliberately is one of the most powerful creative moves available at the moment of capture, and mastering the scale is the gateway to it.

Worked example

Reading the f-stop scale for a blurred background

A student wants the softest possible blurred background for a portrait and has a lens with apertures from f/1.8 to f/22. Which aperture, and why?

Recall what gives blur
A blurred background comes from a shallow depth of field, which comes from a WIDE aperture - and a wide aperture is a SMALL f-number.
Find the widest available
On this lens the smallest f-number, and so the widest opening, is f/1.8 - the maximum aperture.
Choose f/1.8
Setting f/1.8 gives the widest opening, the shallowest depth of field and the softest background blur the lens can produce, with the subject's eyes kept in sharp focus.
Note the trade-off
At f/1.8 the depth of field is so shallow that focusing must be precise (a nose might be sharp while the eyes are soft), and the lens may be slightly less sharp wide open - trade-offs of the effect.

Result: f/1.8, the smallest f-number and widest opening, gives the shallowest depth of field and softest background - correctly reading the counter-intuitive scale to achieve the creative intention.

Typical mistakes

Reversing the f-number logic (thinking a big number means a big opening) - the single commonest aperture error.
Forgetting that each f-stop is a doubling/halving of light, so miscounting stops when balancing the triangle.

Active revision

Photograph the same scene at f/2.8, f/5.6 and f/16 (adjusting shutter/ISO to keep exposure); lay the three side by side and note how the background sharpness and the light change with the aperture.

Depth of field#

AdvancedAQA 7206 Photography (depth of field)Ofqual GCE Art and Design subject content

Depth of field: shallow versus deep

Fig. 3Aperture controls depth of field: a wide aperture (f/2.8) makes only a thin zone around the subject sharp (shallow); a narrow aperture (f/16) keeps foreground to background sharp (deep).

Depth of field is the zone of a scene that appears acceptably sharp, from the nearest sharp point to the farthest. A shallow depth of field means only a thin slice of the scene (say, the subject's face) is sharp, and everything nearer and farther falls into blur; a deep (or large) depth of field means everything from the foreground to the distant background is sharp. Depth of field is one of the photographer's most powerful expressive tools, because it directs the viewer's attention: a shallow field isolates a subject against a soft background, while a deep field presents a whole scene in equal sharpness.

The primary control of depth of field is aperture. A wide aperture (small f-number, such as f/2.8) gives a shallow depth of field; a narrow aperture (large f-number, such as f/16) gives a deep depth of field. This is why portrait photographers, wanting a subject sharp against a blurred background, use wide apertures, and landscape photographers, wanting front-to-back sharpness, use small apertures. Setting the aperture is therefore setting the depth of field, and it is the first decision many photographers make - which is why aperture-priority mode is so widely used.

Two other factors also affect depth of field, and knowing them gives finer control. The first is the distance to the subject: the closer you focus, the shallower the depth of field, so a close-up throws the background out of focus dramatically even at a moderate aperture, while a distant subject keeps more depth. The second is the focal length of the lens: longer (telephoto) lenses give a shallower depth of field than shorter (wide-angle) lenses at the same aperture and framing. So the strongest background blur comes from combining a wide aperture, a long lens and a close subject; the deepest sharpness from a small aperture, a wide lens and a distant subject.

Depth of field is always a creative decision tied to your intention, not just a technical setting. A shallow field says 'look here, and let the rest dissolve' - intimate, selective, atmospheric; it suits portraits, details and isolating a subject from clutter. A deep field says 'everything matters, see it all sharp' - descriptive, expansive, objective; it suits landscapes, documentary scenes and images where the relationship between near and far is the point. Choosing the depth of field is choosing how the viewer reads the space of the image, so it should follow from what the photograph is about.

Because depth of field is so central, it repays deliberate practice: shoot the same subject at a range of apertures and see exactly how the sharp zone grows and shrinks; try focusing close versus far; try a wide lens versus a long one. Learn to previsualise the depth of field a given combination will give, so you can set it to isolate or to describe as your intention demands. Controlling depth of field is one of the clearest examples of a technical control (aperture, distance, focal length) serving an expressive purpose - the essence of AO2.

Worked example

Choosing depth of field for a landscape and a portrait

A student shoots a mountain landscape and a close portrait on the same trip. What depth of field for each, and how do they set it?

The landscape intention
For the landscape they want the foreground rocks AND the distant peaks sharp - a deep depth of field so the whole space is described.
Set the landscape
They choose a narrow aperture (say f/16), a wide-angle lens and focus into the scene, maximising the sharp zone front to back; a tripod handles the resulting slow shutter.
The portrait intention
For the portrait they want the face sharp against a soft, non-distracting background - a shallow depth of field that isolates the subject.
Set the portrait
They choose a wide aperture (say f/2.8), a longer lens and stand fairly close, minimising the sharp zone so the background melts away while the eyes stay sharp.

Result: Deep field (f/16, wide lens, distant focus) describes the whole landscape; shallow field (f/2.8, long lens, close subject) isolates the portrait - depth of field set from the intention using aperture, lens and distance together.

Typical mistakes

Confusing which aperture gives shallow versus deep field (wide aperture/small f-number = SHALLOW; narrow aperture/large f-number = DEEP).
Treating depth of field as a technical accident rather than a deliberate choice about where the viewer's attention goes.

Active revision

Set up a subject with objects at different distances; photograph it at f/2.8 and f/16, then again focusing very close and then far; compare how the sharp zone changes with aperture and distance.

Shutter speed and motion#

StandardAQA 7206 Photography (shutter speed)Ofqual GCE Art and Design subject content

The shutter-speed scale

Fig. 4Shutter speeds in stops: fast speeds (left) freeze motion and can be hand-held; slow speeds (right) blur motion to convey movement but need a tripod to avoid camera shake.

Shutter speed is the length of time the shutter stays open to admit light, measured in fractions of a second (and, for long exposures, in whole seconds): 1/1000, 1/500, 1/250, 1/125, 1/60, 1/30, 1/15, and so on down to 1 second or longer. Like aperture, it works in stops - each step doubles or halves the time, and so the light. A fast shutter speed (a short time, such as 1/1000) admits little light; a slow shutter speed (a long time, such as 1/15 or 1 second) admits much more. So shutter speed is the second way of controlling exposure, trading in stops against aperture and ISO.

Shutter speed's creative side-effect is how motion is rendered. A fast shutter speed freezes movement, capturing a sharp instant - a fast shutter can freeze a sprinter mid-stride, a splash of water or a bird in flight. A slow shutter speed lets anything moving blur across the frame during the exposure, conveying motion, energy or the passage of time - a slow shutter turns flowing water silky, car headlights into streaks of light, or a moving crowd into a ghostly blur. Neither is 'correct'; the choice depends on whether you want to arrest the moment or express the movement.

The other consequence of a slow shutter is camera shake. When the shutter is open for a long time, any movement of the camera itself - including the tiny tremor of your hands - blurs the whole image, not just the moving subject. A rough rule of thumb is that you can hand-hold down to about one over the focal length (so a 50mm lens down to about 1/50 second) before shake shows; below that you need to steady the camera, most often on a tripod. So slow-shutter effects (silky water, light trails, low-light shots) almost always require a tripod, while fast shutters can be hand-held freely.

Shutter speed also interacts with the light available. In bright light, a fast shutter is easy; but a slow shutter in bright light may let in too much light and overexpose even at the smallest aperture and lowest ISO - which is where a neutral-density (ND) filter comes in, cutting the light so you can use a slow shutter in daylight (for silky water at midday, say). In dim light, the opposite problem arises: to keep the shutter fast enough to avoid shake, you may have to open the aperture wide and raise the ISO. Reading the light and choosing the shutter speed accordingly is part of the balancing act.

For your practice, decide what you want motion to do and set the shutter first when it matters. Freezing a decisive action? Choose a fast shutter (1/500 or faster) and balance aperture and ISO. Expressing movement - flowing water, a blurred crowd, light trails? Choose a slow shutter, mount a tripod, and balance with a small aperture, low ISO or an ND filter. Shutter-priority mode supports this. Because shutter speed controls both light and the depiction of time, using it deliberately is how photographers turn motion into meaning.

Worked example

Choosing a shutter speed for silky water at midday

A student wants a silky, blurred waterfall but it is a bright, sunny day. What do they set, and what problem must they solve?

Choose the effect and speed
Silky water needs a slow shutter - say 1 second or longer - so the moving water blurs into a smooth veil during the exposure.
Mount a tripod
At 1 second, hand-holding would blur the whole image from camera shake, so the camera must go on a tripod to keep the still parts sharp.
Spot the exposure problem
In bright sun, a 1-second exposure lets in far too much light even at the smallest aperture (f/22) and lowest ISO - the image would be badly overexposed.
Solve with an ND filter
Fit a neutral-density filter to cut several stops of light, allowing the 1-second exposure to be correctly exposed in daylight - the standard solution for slow shutters in bright light.

Result: A slow shutter (1 s) on a tripod gives the silky water; a neutral-density filter solves the overexposure of using a slow shutter in bright light - shutter speed set for the motion effect and the light balanced around it.

Typical mistakes

Using a slow shutter hand-held and getting whole-image blur from camera shake, mistaking it for subject motion blur.
Forgetting shutter speed is a stop scale that trades against aperture and ISO in the exposure balance.

Active revision

Photograph moving water or traffic at 1/500, 1/60 and 1 second (on a tripod for the slow ones); compare how the motion is rendered from frozen to fully blurred, and note where camera shake would appear hand-held.

Lenses, focal length and the light path#

AdvancedAQA 7206 Photography (lenses and focal length)Ofqual GCE Art and Design subject content

A converging lens forms the image

Fig. 5The camera lens is a converging lens: rays from the object are bent to converge into a real, inverted image at the sensor plane - the optical basis of every photograph.

The lens is what forms the image, and understanding a little of how it works illuminates every camera choice. A camera lens is (in effect) a converging lens: it bends the rays of light coming from the scene so that they converge to form a real, focused image on the film or sensor at the back of the camera. Because the rays cross as they converge, this image is inverted (upside down and left-right reversed) - which is why the image on a large-format camera's focusing screen appears upside down. Focusing the lens moves it slightly so that the sharp image falls exactly on the sensor plane for a subject at a given distance.

The key property of a lens is its focal length, measured in millimetres (for example 24mm, 50mm, 200mm), which determines the angle of view and the magnification. A short focal length (a wide-angle lens, e.g. 24mm) takes in a wide angle of view, fitting a lot into the frame and making near things loom large relative to far ones (exaggerating depth and space). A long focal length (a telephoto lens, e.g. 200mm) takes in a narrow angle, magnifying distant subjects and compressing the apparent distance between near and far. A standard lens (around 50mm on a full-frame camera) roughly matches the perspective of human vision, looking natural.

Focal length is therefore a compositional and expressive tool, not just a way of getting closer. A wide-angle lens, used close, gives sweeping, dramatic, deep-space images and is used for landscapes, interiors and immersive scenes - but it can distort faces unflatteringly if used close for portraits. A telephoto lens flattens perspective, isolates a subject, and gives a shallower depth of field, which is why longer lenses (around 85-135mm) are favoured for flattering portraits with soft backgrounds. Choosing the focal length changes the whole feel of the image - the angle of view, the sense of space, the magnification and the depth of field.

Lenses come as fixed focal length (prime) lenses or zoom lenses that cover a range. Prime lenses (a single focal length, e.g. a 50mm) are often sharper and offer wider maximum apertures (for low light and shallow focus), and they encourage you to compose by moving; zoom lenses (e.g. 24-70mm) are versatile, letting you frame without moving, at some cost in maximum aperture and sometimes sharpness. Special lenses - a macro lens for extreme close-ups, a very wide fisheye, a very long telephoto - extend the range further. The lens you choose shapes what images are possible.

Understanding the lens as the image-forming element ties the topic together. The converging lens forms the image; the aperture inside it controls how much light passes and the depth of field; the focal length sets the angle of view, magnification and perspective; and focusing places the sharp image on the sensor. Together with shutter speed and ISO, these are the controls that turn a scene into a deliberate photograph. Knowing what each does - and that they interact - is what lets you previsualise an image and set the camera to make it, rather than accepting whatever automatic gives you.

Worked example

Choosing a focal length for a flattering portrait

A student's portraits taken on a wide-angle lens up close look distorted - big noses, bulging faces. Explain and fix it with focal length.

Diagnose the cause
A wide-angle lens used very close exaggerates near-to-far size differences, so the nearest feature (the nose) looms large relative to the ears - the unflattering distortion.
Recall telephoto perspective
A longer (telephoto) focal length compresses perspective, so features sit in more natural proportion, and it lets you stand further back while still filling the frame.
Switch to a portrait lens
Use a lens around 85-135mm and step back; the face renders with natural proportions and the compression flatters the features.
Note the bonus
The longer lens also gives a shallower depth of field at the same aperture, softening the background to isolate the subject - a further portrait benefit of focal length.

Result: The distortion is wide-angle-close perspective; switching to an 85-135mm lens and stepping back gives natural proportions and a softer background - focal length chosen for its perspective, not just its reach.

Typical mistakes

Thinking a telephoto lens just 'zooms in' rather than also compressing perspective and reducing depth of field.
Using a wide-angle lens close for portraits and getting unflattering facial distortion.

Active revision

Photograph one person from the same framing with a wide-angle and a telephoto setting (moving closer for the wide, further for the tele); compare how the face, the background size and the sense of space change with focal length.

Lighting, filters and viewpoint#

StandardAQA 7206 Photography (lighting, filters, viewpoint)Ofqual GCE Art and Design subject content

Beyond exposure and focus, the photographer controls light, filters and viewpoint at the moment of capture, and these are where technical control becomes visibly creative. Light is the very substance of photography, and its quality, direction and colour transform a subject. The quality ranges from hard (direct, undiffused light, giving sharp-edged shadows and high contrast - dramatic but harsh) to soft (diffused light, as on an overcast day, through a window or through a diffuser, giving gentle gradations - flattering). Learning to see, choose and shape light - whether natural daylight or artificial studio light - is one of the deepest photographic skills, developed further in the genre topics.

The direction of light dramatically changes how a subject reads. Front lighting (from behind the camera) is flat and even, revealing detail but little form; side lighting rakes across the subject, revealing texture and three-dimensional form through the shadows it casts (excellent for showing surface and shape); backlighting (from behind the subject) can create silhouettes, glowing rim-light around edges, or luminous translucency. Top, under and three-quarter lighting each have characteristic effects. Because direction sculpts form and mood, choosing where the light comes from - by moving the subject, the light or yourself - is a central creative decision.

Filters are optical accessories that modify the light entering the lens, and a few are worth knowing. A neutral-density (ND) filter cuts the amount of light without changing its colour, allowing slow shutter speeds or wide apertures in bright conditions (for silky water or shallow focus in daylight). A polarising filter cuts reflections and glare from non-metallic surfaces (water, glass, foliage) and deepens blue skies, saturating colour. In black-and-white photography, coloured filters alter how colours translate into grey tones (a red filter darkens a blue sky dramatically). Filters give control at the point of capture that is hard or impossible to replicate afterwards.

Viewpoint - where you place the camera - is one of the photographer's most distinctive tools, because the camera is mobile even when the subject is not. The same subject photographed from a low angle (looking up, which tends to empower or monumentalise), a high angle (looking down, which tends to diminish or give an overview), close up (intimate) or far off (contextual), from the front or an oblique angle, reads quite differently. Choosing the viewpoint deliberately - moving around a subject to find the most telling angle rather than shooting from wherever you happen to stand - is a fundamental compositional decision explored further in the visual-language topic.

Together, light, filters and viewpoint are the creative controls that sit alongside exposure and focus at the moment of capture. A technically perfect exposure of a badly lit subject from a thoughtless viewpoint is a poor photograph; the considered control of light (its quality and direction), the purposeful use of filters, and the deliberate choice of viewpoint are what make a photograph, as much as the exposure triangle does. Practise seeing light and choosing viewpoint constantly - they develop the photographic eye that the rest of the course builds on.

Worked example

Using light direction and viewpoint to characterise a subject

A student wants a weathered old fisherman to look dignified and full of character. Advise on light direction and viewpoint.

Choose the light direction
Side (or three-quarter) lighting rakes across his face, throwing the lines and texture of weathered skin into relief - revealing the character that flat front light would smooth away.
Choose the light quality
A fairly hard or directional soft light preserves the texture (very soft, flat light would lose it), so the surface and form read strongly.
Choose the viewpoint
A slightly low angle, looking a little up at him, lends dignity and stature, presenting him as monumental rather than diminished.
Combine for meaning
Side light for character and texture, a low viewpoint for dignity, and a close framing for intimacy together construct the dignified, characterful portrait intended - before any processing.

Result: Side lighting reveals character and texture while a low viewpoint lends dignity - light direction and viewpoint chosen deliberately to construct the intended reading of the subject.

Typical mistakes

Ignoring the quality and direction of light, or shooting in flat front light that hides form and texture.
Shooting from wherever you happen to stand instead of choosing the viewpoint that best serves the subject.

Active revision

Photograph one object in hard side light, soft window light and backlight, and from a low angle, eye level and a high angle; compare how the light and viewpoint change its form, texture and mood.
