Got a roll of film developed, from a camera I'd never used before. Everything turned out black. None of the pictures can even be seen. I had it done at WalMart, probably not a great move, but no studio in town to have it done by. The film had been sitting out, not in a case, for five or six years at least. I did shoot probably half the roll at the wrong ASA, 100 as opposed to 200, but that shouldn't completely black out everything, should it?
