Any way to reduce the noise in my pics at full resolution (2272 x 1704)? I get it at ISO50, which is what the example pic I'm going to post is. Camera was set to ISO50, SuperFine Large Resolution, no flash. Here is the pic cropped, and resized in photoshop. Notice the noise in the sky? Here is the Full Size, unedited pic...loaded with noise. Full Size Is this just the Canon A80 or are my settings off? How can I reduce the noise?
