Photos that I shoot for hobby are mine, and I will not give up copyright to them. But when I want to enter competition that requires me to give over copyright, i will go out to shoot that photo for the sole purpose of entering this competition, and be prepared to give them the copyrights. I will not choose a photo from my personal collection and give to them.
I want to enter competiton, so LL have to abid by their rules, if i cannot accept their rules, I won't enter.
