Doug,

Found this link that explains ISO a bit! From my understanding the higher the ISO the less light is needed BUT more noise can be introduced into the image under certain conditions. DSLR cams are better suited at it than the "PROSUMER" models like my Canon G6. If I goto higher than 200 ISO, the images becomes pretty useless! There are products like noise ninja that can "fix" noise, but again your (D70?) should have no problems with the higher settings! If your using RAW format...this may not be any issue. (I'm not that familiar with RAW!)

L8r!
Joe
