You don't study photography, you just do it.
Most photographers work best alone, myself included.
I am a professional photographer by trade and an amateur photographer by vocation.
I'm not a serious photographer like many of my contemporaries. That is to say, I am serious about not being serious.
Color is descriptive. Black and white is interpretive.
You must have a visual sense if you want to be a photographer. It is a very subtle thing, this visual business.
