I have an issue with sharpness; at first I thought it was a camera focus issue but after so checking I'm not certain - which leaves me looking for answers. Here is the background: I have three digital cameras - Nikon D3100, D7000 and a cheapie Kodak P&S. I use iPhoto and Apple Aperture for storage and photo editing. Photos imported from all three cameras appear fuzzy, soft or generally out of focus. I have to increase the sharpness "radius" feature and "definition" to get tack sharp pictures. Since it happens with all three cameras I'm left with the conclusion it is either the software, my iMac, or my old eyes. I would be interested in opinions or suggestions? Thanks...
