Hello everyone! I am a newbie who needs some help. I have been asked to enter into an agreement where I would "joinly and severally" own the copyright to my photos with another person. The other party promises this means I retain all the rights to the photos, but I'm doubtful. I can't find any information on this type of arrangement. Also, what should I charge for this? I ask because it is a very large number of photos (just over 4,000). They are digital pictures of the Middle East taken with a D50.
