When looking at Photography as a possible profession, you have to ask yourself, "What's my angle?" In other words, what do you want to photograph? Al eluded to this when he talked about finding outlets like specialty magazines for submitting your work to. You have to get out there and find that one angle that you not only love to shoot, but that tickles you to edit, review, fame and look at again and again.
Are you a formal portraits photographer? What about wildlife? Babies, or could it be events? When you know what your point of view is, you will be able to get out and market yourself in the appropriate circles and start making your dreams come true!
