CREATE A NATURAL-LIGHT STILL LIFE SHOT
Control lighting without a studio by altering shutter speed, f-stop and ISO to produce a focused light effect
Natural light may be harder to control than studio lighting, but there’s still a way to shape the light and control where it spreads within the frame. Find out how in this shooting tutorial
One of the advantages of shooting in a studio is that the photographer has full control over the intensity, direction and spread of light, allowing easy management of background detail. Furthermore, in a studio setting, seamless backgrounds can be used to produce a clean, distraction-free environment, ideal for portraits or still life subjects. There are great benefits of natural light however – it is soft, directional and freely available. It therefore pays to be able to bring studio-like effects
1
PICK A SUBJECT First you need to select a specimen that is well lit by natural daylight. Ideally the background will be more shaded, so that there is already contrast – for example, patches of light in woodland are perfect for this style of shooting.

SWITCH TO MANUAL MODE Set your camera to Manual and dial in the settings calculated in step 3. This will guarantee you have full control over the brightness of your shot and that exposure won’t change unexpectedly as you compose. outside. The technique discussed here is a simple method of shaping light, by controlling where it spreads within the frame. This is done by shooting in direct sunlight (slightly diffused by cloud cover where feasible) and using exposure controls to eliminate ambient light as much as possible. This generates a high-contrast, underexposed look, which approximates the appearance produced using strobe lights and a black background. Direct sunlight is best as the intensity will widen the exposure differences between the illuminated

SELECT APERTURE AND ISO Choose an appropriate initial aperture for your subject, starting around f11. Ensure that you use the lowest ISO setting available to minimise ambient light capture, generating increased background contrast.

INCREASE SHUTTER SPEED Next shorten your exposure by around one stop to underexpose the background and render it solid black – if your metered exposure was 1/125sec, increase this to 1/250sec etc. Leave f-stop and ISO fixed for now. and shaded areas of the scene. Try shooting in the mid-afternoon as this will place the sun high in the sky, but with some direction in the lighting. Precise metering will ensure that no highlight detail is lost and that the subject itself does not seem underexposed – only shaded areas will be noticeably darkened.

METER FROM THE HIGHLIGHTS Use Spot metering mode and place your AF point over the brightest part of your subject, to calculate exposure from the highlights. Take note of the exposure settings that any of the P, A or S modes suggest.

CUSTOMISE SETTINGS Shoot and review your image. If you need a darker background, increase exposure further in halfstop increments until you have a seamless background effect or alternatively, select a higher f-number.
