When you decide to use a certain camera, focal length, flash vs natural light, black and white versus color, etc — think about the added meaning you want to give to your photographs. For example, if you use a 28mm lens (rather than a 50mm lens) consider why you are trying to do that. Instead of just making more distortion for the sake of it — perhaps you should use it to create a more sense of immediacy and intimacy with your subject. When shooting in black and white – are you trying to document something sad and depressing or want to focus on forms and shapes? If working in color- what about the color adds meaning to your photographs?
Experiment freely with your photography, but don’t get carried away for trying something new for the sake of trying something new and trying to be different. Think about the meaning you will add to your images.
