If someone tells you that he has never taken a bad shot, he's flat out lying. All photographers, from the greats like Ansel Adams down to a kid playing with a camera, have taken tons of bad photos. We're giving them their chance to shine here!
Lomography can sometimes be very unpredictable, especially if you use techniques like shooting from the hip. You can never really tell what your images are going to look like until you get them back from the lab. I often look through my newly developed photos and put aside particular shots that I am not quite happy with. I will then work on these shots, manipulate and experiment with them until I have created something that I love.
