I have a Nikon D5500, and I made the mistake of changing some settings in Movie mode to see what they would do. Now I can't get it out of the movie mode. When I switch to Manual mode, I can't adjust the shutter speed below 1/60 second. If I try, the video camera icon and 1/60th of a second lights up under it, and it refuses to let me adjust it any slower. And all the icons around the perimeter of the monitor pertain to movies, not photos. There has to be a way to return it to photo mode, but I can't find anything about it in the manual, nor online.
If you know, please inform me. This is very frustrating.
