Re: Questions- Need help!
Benji,
My understanding is that, depending on the camera, center of the histogram is not 18% gray.
Lee Varis published a method in his book Skin and in a Magazine article referenced somewhere else on this forum, on how he calibrates.
On important point, is if you are going to use a flat card as the starting point to make sure the angle of the card to the light and lens doesn't allow extra or remove light during the capture. This is the angle of incidence equals angle of reflection relationship all over again. That is why a 3-D target is preferred, especially one that mirrors your primaary subject matter.
