I'm what I might call a semi-serious amateur, I have some pro kit (lighting, tents etc) but not such a pro camera (Fuji S9600). In addition to personal photography, I also do product photography for my own design work - catalogues, brochures, web sites etc. A problem that I appear to notice increasingly, is that shooting indoors under studio lights tends to give me 'furry' images whereas shooting the same products outdoors gives me nice sharp images. I always shoot at the lowest ISO I can (80) and use auto focus. Invariably, the indoor shots always tend to turn out slightly dark but can this 'darkness' throw off the auto-focus or affect the sharpness of the shot? I do have a light meter, but the values it tells me to dial into my camera tend to be outside of the range of the camera, so I tend to use a trial and error method by taking repeated shots and looking at the histogram and blinkies to ensure nothing's burning out. Any suggestions?
