The copyright owner has the right to allow others to copy, edit, distribute etc., but the copyright still remains with them. re-cropping and minor edits wont change that.
However, if the editing was so extreme that it could be considered transformative then it might be different. If you took 8 photos and chopped them up and made a collage, that could be considered an original creative work and subject to copyright protection. That still wouldn't alter the fact that the photographer owned the copyright on the original photo.
