ok... my digital camera has a mechanical shutter, and settings to change the shutterspeed and aperture size...
that makes sense, but why does a digital camera have a range of iso settings? :? isn't iso all about chemical stuff? what changes do different iso settings affect in the making of a photograph in a digital camera?
i know about graininess and exposure, thats not what i'm asking
i understand how to work it, i'm just curious about how it works
