Exposure & Focusing, getting it right!

In order to get the best possible results from your camera and the infra-red images you take, you will need to shoot everything in RAW (NEF), this is not an option, but a necessity. Why? because you have better control over the final exposure and complete control of your white balance settings, which, when shooting in infra-red is vitally important, as you will see later in this section. I preferred to let Nikon's 3D-Matrix II metering system take care of my exposure, it's not that often it gets fooled. Your main consideration, when shooting infra-red images with a non-modified camera should be that of camera shake! always use a good study tripod, again this is a necessity, not an option!

Because our camera lenses are designed to work best under normal lighting conditions and not under infra-red radiation, there is a slight point of focus shift. Some older lenses will have a red infra-red focusing dot, newer ones may not. To compensate for this focus discrepancy it is best to stop your lens down to a small aperture (f22) thereby maximising your depth of field. By focusing on the most important element within your composition, out of focus images have never been a problem for me using the above equipment and working practise.
