By the way, beware of the main National Geographic reader photo contests... read the terms carefully to understand what rights you may be giving away. They seem to allow people to download the winning images, which pretty much kills any commercial value that the image might have had for you in the future. In fact, by giving National Geographic a steady stream of free photographs, user submissions contribute to the death of a viable market for nature photographers. National Geographic used to be the one everyone always used to want to work for, now their practices may help put emerging professional nature photographers out of business?
