I was wondering when something like this will pop up. An app that not only shares information about photography, but also tells you how to shoot. Camera51 is just that. An app that tells you how to shoot to get better photos.
I am really not sure what I think about this kind of technology, on one hand smartphone photographers do sometimes spray and pray, but on the other, I am not sure I am comfortable with the idea of letting an app telling me how to shoot.
