Is it normal for a photography contract to have a clause stating that the photographer has the right to hire someone else if he becomes unavailable?This photographer has amazing pictures & comes highly recommended by 2 friends. All his work is great and we are very comfortable with them. But this paragraph in the contract bothers me. He said it's there in case of emergencies. Is this normal wording? And if it's not, how would you go about asking for it to be changed?
