"Booming" sun photos should not have noise!. Seeing as how it happens on manual and not on program, it may be that you are choosing a high ISO or underexposing or both!. Try it again, outside in bright sunlight at mid day, with the ISO as low as possible (100 ISO or below) Use the sunny 16 rule!. Aperture at f/16, shutter speed at 1/100 (at ISO 100) There should not be any noise to speak of!. If there is, I might then think the camera has a problem rather than the operator!.Www@QuestionHome@Com
