Or am I missing something ?
The "grain" (digital sensor noise, actually) depends on the ISO selected. Basically, the stronger the signal (light), the least important noise will be in the final stored value. I'm not an expert on digital cameras, but that's the way it works if I'm not mistaken. j -- --------------------------------------------------------------------------- Juan J.
