A print release is a document that allows the client to make other prints, including on various material(s) of the images they have received from Anthony Kearney Photography, the photographer. However, one key thing to keep in mind is that a print release is specifically geared to personal usage. This means that the images can be used on social media, on canvases and prints and to a certain extent be shared with family.
The client does not have permission to edit the image, make a derivative of the image, claim the work as their own, and most importantly cannot use the image for commercial gain! In order to do any of these things, a print release is not enough, the client must get copyright permission.
