Sigma SD1 and SD15 for Digital Infrared Photography » Step 1 Bracket shots
Metering in infrared can best be described as guess work. But Auto Exposure Bracketing helps to quickly fine-tune the exposures. I look for good rich shadow tones, and an overall red-tinted image. If it’s mostly pink, or there’s areas of yellows and whites on the LCD screen, the exposure was too long. In this series of images bracket at 2.7 EV intervals, the far left image has the best exposure.
