The owner of a local organization that puts on sports races has left me a message saying that I am infringing on his business by selling photos on my photography website, to racers in the event, that I have taken of sports events organized by his business. These races are in the public view. I want to know where I stand before I return his call. This organization hires a photographer to sell photos on their website as well and that I am infringing on his business. Thank you for your input. I might add that some of my photos show the start and finish line banner which has the name and business logo of the orgnanizer. I also have megatags and SEOs that have the title of the race and the organizations name in them. So am I infringing by selling photos of the races at all or by having the name of the organization and logos in the photos that I am selling? Otherwise my photos are of cycling or running racers running through the mountain side.
