Arrow keys change LCD brightness even when LCD sensor is not covered
Created originally on Bitbucket by Anonymous
I did a photo shoot with a couple of models last night and found it extremely difficult to review photos as the Up/Down arrow keys kept changing the screen brightness instead of panning.
I was in a well lit room with several spot lights and ambient light (to give you an idea of how bright it was, I was using ISO200, f3.5, 1/125sec with flash -2EV).
Intermittently I could pan up and down but I couldn't find a consistent way to make it work, it was really frustrating!
