Stemming from a topic in a different sub-forum, I was wondering how people feel about taking photographs for free. I understand the reasons for both, mainly; many people live off their photo revenue and doing jobs for free can cheapen it for the rest of photographers. Then there are those that feel since it's "only a hobby" or however they'd like to word it, then working for free is no skin off their back and it's fine. When do you cross the line? Should hobbyist start to charge, and if so; when can you tell if you're good enough to charge, and how much? (although the latter part of the question is dependent upon the former.) This isn't a discussion about whether or not it's right or wrong to work for free, but rather; when do you begin to charge?
