What qualifications do you use in regards to quality?
I'm still working on how to distinguish "quality" photographs. I don't believe there to be such a thing as a "professional cosplay photographer", really. It's very subjective. If you would like to share your thoughts, I would like to know.
Some ideas I had in mind are, non snapshot, properly exposed, or enhanced, aesthetically pleasing, preferably shot with an SLR of some sort. Caliber of professionalism is not what's important, but I will develop a group of people who will decide what submissions will be processed.
I've seen first hand what happens when any photo is allowed - there is a massive flood of every possible shot from a point and click camera. But please feel free to submit anything you would like. As stated previously, this is still in development. ^_^
