To be a good photographer you need to know the basics, that you'll learn by studying or practising a lot. Your first photos will be awful, but would we be without them? (although you should never be perfect, that'd be too boring!) Remember that what really matters in photography are technique and emotions, but sometimes technique can be set aside to stress the emotional side. Photography is like a ballerina, you can make mistakes on the steps but if you convey real emotions no one will notice. As I said before, I'm not a photographer (who knows, maybe one day) but I find the power of photography is amazing: you turn on your camera and all worries disappear when you look into the viewfinder.
