I have access to a really nice Canon EOS (not mine unfortunately, but I get to play with it). I was wondering if folks had a sense of the best general setting for manual photos of a tank?
To date, my attempts have been to set the ISO to 800 or 1000, set the aperture as narrow as possible to improve my depth of focus, pray the fish pauses as I VLH (that's "vary like hell") the shutter speed until I get a somewhat acceptable image. I also use a tripod. Then I try to correct the best shots using Photoshop. Plants, easy! Overall tank, no sweat. Fish seem darn near impossible!
Not being a photographer, does the higher ISO on a digital camera result in blurring (graininess) like you'd get on high ISO 35mm film? Should I use a larger aperture and a faster shutter speed?
Any general suggestions based on experience are welcomed!
