I've never attempted to get any of my photos published, and I've never entered a photo contest. And although I doubt that my stuff is likely to beat out the kind of amazing photos I see posted here on Wetpixel, I sometimes find myself looking at dive magazines and thinking, "Geez, I've got better shots than THAT!"
I assume I'm not alone in the above sentiments, but I really have no idea how to get started. Is there a "Photo submission for dummies" type article anywhere that not only lists publishers/contests to whom photos might be submitted, but explains some of the do's and don'ts (e.g., protecting your copyright, when/how much to charge, etc.)?
