I have had my D5100 for about three years, but never really delved into using it to its full extent. I have tried using manual mode, and have set the ISO, f-stop, and shutter speeds on it to what I want, but I have barely used it because my settings would change on their own after taking a picture. I was under the impression that manual means I set the settings and the camera doesn't touch them.
I have found it very frustrating. Why is the camera doing this, and how do I stop it? I want my settings to stay until I change them. :)
