I just found this forum, and am hoping you guys can help me out on this. My husband and I, along with our 10-year-old twin boys, will be riding bicycles from Alaska to Argentina leaving in June. My husband and I are both teachers, so we have decided to partner up with Reach the World to have an interactive website and other things to teach kids in inner city schools about the world. We are VERY excited the journey and about the possibilities of bringing the world to the kids. Reach the World (RTW) is a good organization, but for some reason they are insisting in holding the copyright for all materials we post on their site. We don't mind giving them the copyright of our written stuff - we can always rewrite in the future if we want to. But we are hesitant to give up our photos - we can't retake them at a later date. So - it looks like our options are limited, and we want to make sure we make an educated decision here. We could just give them our crappy photos (of which there will be plenty!) or we could try to take two of the best ones. Generally, we will know when we are taking a great photo - and we could try to take two. We could send one to RTW, and keep the other for us. But that's where we aren't sure about the legality of it all. At what point are they completely different photos? Obviously, if we take one looking west and another of the same thing looking east, they are different. But what about slight differences? We've taken some photos before that we had a VERY difficult time telling the two apart. Obviously there are slight differences, but not much. So I guess my question is: how close is too close? At what point would it become a copyright violation if we used the duplicates for ourselves?
