From the Author: Top Five Exposure Tips Author Jeff Wignall 1. Avoid extreme contrast. Try to work early or late in the day, or on slightly overcast days to avoid contrast problems from harsh daylight. Digital-camera sensors can only record a limited contrast range and the gentler the light is, the more accurate your exposures will be. If possible, you can also move your subject to an area of open shade. 2. Shoot in RAW format. Use the RAW format if your camera offers that option. In the RAW format you can alter both exposure and color temperature (white balance) during the editing process. This means you can be off by a few stops in exposure and still correct the exposure in the original file. You can also fine-tune the white balance of the original file. RAW requires a few more steps in editing, but the effort is well rewarded. 3. Meter a middle-tone subject. Try to select a middle tone when you're metering and you'll get much more accurate exposures. Subjects that offer a natural middle town include green grass or foliage, clear blue skies and weathered barn wood. You can also carry an 18% gray card (available at photo stores) and meter from that: just place the card in the same light as your subject, meter it and then use that exposure setting. 4. Use fill-in flash for outdoor portraits. Portraits shot in bright daylight often have distracting shadows under the nose or below eyebrows. By turning on your built-in flash in daylight you can light open those shadows and still keep a natural-light look. Read your manual for tips on using fill-in flash. 5. Use a tripod. Using a tripod enables you to use the full range or reciprocal aperture and shutter-speed combinations. Yes, image-stabilization systems will help keep the camera steady with moderately slower shutter speeds, but won’t help much if you want to make a ten-second exposure of a waterfall or a twilight skyline. Placing your camera on a tripod also slows you down and gives you more time to consider exposure options. From the Author: Example Photos Shot with a 300mm Nikkor lens.
