I shoot with a nikon D600 usually on an auto setting and when I take pics of people against the sky or water that part of the picture is washed out like it has bad exposure. I shoot in the shade or cloudy days when I can and with no flash. Is there a setting I set to fix this on auto or do I need to change to P, A, S or M? Any suggestions. I tried the scene setting on landscape and portrait and I got the same thing.
