Hey, I just upgraded from a d40 to D300s. Big step, a lot of things to learn. For some reason in all of the modes manual, A, P mode, while taking the same shot over and over, it decreases the shutter speed each time. In S mode it adjusts the exposure. I initially thought this was my Active D lighting, but I turned that off. This just adds way too much exposure to my pictures. I know it is something funky in my settings Can someone please help?
