I have learned something after so many years of taking pictures. I don't think I really understood it until recently, however. For me, taking pictures is an exercise in patience and perseverance. For every ten pictures I take I find one or two that I'm happy with. I have come to really enjoy the process from taking sometimes hundreds of shots to sorting and tweaking them afterwards. I would love to earn a living with my photography but it is ultimately the process from which I get the most pleasure.
I never really thought about getting a formal education in photography. Honestly that would probably dramatically improve how i understand the camera as a tool, and give me more tools to take better shots...but on the other hand, learning on my own is also a lot of the fun.
