I've often wondered about this. I have decent Disney vacation photos, but yeah, anyone and everyone photos Disney, lol. However, I've been told by very credible sources in the sporting world that my photos are phenomenal (they've been around this sport for well over 25+ years and have seen it all) and that I should submit stuff to magazines and such.
I honestly have no clue where to start, nor did I ever expect anything to come of me just taking pictures, lol. That said, I have no idea as to the submission side of things and where the compensation enters the picture (haha no pun intended).
