So my friend (guy I work with) is getting married tomorrow. They were scheduled to be married outside but due to the weather, they had to use their backup rain location which is in a dimly lit recital hall. When he told me this, I made sure to explain that he needed to let his photographers know of the change ASAP so they could readjust strategy. (Side note: He paid a professional photographer a lot of money ~ $3500 to come shoot his wedding. This isn't like he asked johnny shutterbug to shoot it for $300). It's a 2 shooter operation (Husband and Wife) So he calls them and tells them about the backup location and that everything is moving inside. Well they took the opportunity to tell him they wouldn't be coming because a relative died and they would be attending the funeral. I understand family death is a serious thing so that isn't the issue but they literally gave him 24 hours notice In the contract, which he read and signed, it said that in the event that they were unable to attend the wedding, that they would assign replacement for their absence. ALSO in the contract is the clause that states that there shall be 2 photographers. They are sending 1 photographer NOT associated with their business but rather someone that they have worked with before. So he asks me over the phone (about 30 minutes ago) if it's a breach of contract for them to send only 1 photographer considering the clause stating there shall be 2 photographers. I told him that without reading the contract myself that I couldn't be 100% sure but it sounded like it to me. Then he asked me if I would come and shoot as a second shooter but that he was worried about stepping on the other photographers toes. I told him that unless there is a clause that says he CANNOT hire another photographer, that I could come and shoot it. So I'm shooting his wedding tomorrow as a lone gunman. I understand that he has a contract with this other photographer but they're screwing him out of 1 photographer and I would consider that grounds to change the game plan. Usually I wouldn't impose on another photographers territory but I feel like he deserves to have what he expected to have in the first place. Did I instruct him correctly? Also what would you do in this situation?
