Was surfing the net and came across this interesting contest that will be held in Denmark: Gammelgaard Monochrome 2011.
You have the chance to exhibit your works and to donate prints for a charity organization teaching photography to children living in India slums. Besides, first prize winner will get 7000 euros, second price 2000 and third 1000!
I checked out their rules and they seem ok, not stealing your rights.
Check it out here. Good luck!
