The sensors in digital cameras don't " see" the light in the same way as film, ie I.S.O. on a digital sensor isn't necessarily the same speed as I.S.O. 100 on film even using a separate hand held meter , and before you shoot me down I base this assertion on an article I read in the British version of Professional Photography Magazine a couple of years ago in which they extensively tested this matter, and came to this conclusion, which I still have.
