I shoot photos at dog shows of my favorite breed. I know all the owners and typically share my photos with them for their personal enjoyment and mine. I was contacted by a dog owner who wants to use one of my photos in an advertisement of her dog handled by a third party. I really want to be compensated if my photo is used in advertising.
The third party is clearly identified as is the judge. Is a release required by the handler and judge if I sell a photo they are in? Thanks.
