Open Content Photography Program
The "Open Content Photography Program" was created to help people learn professional photography. It is not a book about photography it is a book about learning photography. Open Content means anyone can, not just read it, but to improve it.
I think the term professional photography is misused here. Professional photographers are those who make their living from photography. Very few people with little or no prior knowledge will make it as a 'pro' without formal training and work experience in a field as competitive as photography. Maybe the word professional should be dropped and replaced with 'professional techniques of photography'.
