[QUOTE="Mike D90, post: 230513, member: 17556"] I am not making a direct connection between aperture and grainy. The connection I am attempting to make is between aperture and shutter speed and/or ISO changes. Aperture controls the flow of light through the lens like water through a hose. If I stop down, shutter speed will have to slow down or ISO will have to go higher. Since I try to keep shutter speed above 1/1000th it will only bump my ISO up. That is where the grainy/softness seems to happen. I do understand that smaller aperture will increase overall sharpness due to a better DOF. However, it affects exposure too. [/QUOTE]
