All you photographers out there; you may want to get in on this. The Red Bull Illume is an international photography competition focusing on extreme sports. It’s not about shooting someone going the biggest, it’s about shooting a beautiful photograph of something sport related.
Even though It doesn’t have fixed gears or track bikes as a category, I’m sure you can find another sport to pick!
More information can be found here. There’s also some amazing shots in the Gallery section.
Edit: Nick from Redbull commented that there is a category where fixed gear shots could be entered, so shoot away!
