So I am having some sever exposure issues with my Nikon and I am trying to figure out what is going on. I had my aperture at 5.3, a shutter speed of 1/40 and ISO of 800 and it is still coming out underexposed, it was not a low light situation either. This has been happening all day. I checked the exposure compensation and it's set at 0, but even if I change it one way or the other it still doesn't help the exposure. Not sure what is going on but I really want the proper exposure on my pics!!!!
