I took photos at hundreds of courses back when I was traveling around to get my education. A handful of clubs (Ekwanok, SFGC) asked me to sign a release saying I would never sell the images, so I've contacted those clubs anytime someone wanted something.
For the most part, I don't worry about posting these pictures or even selling them. For example, many other photographers have taken pictures of Cypress Point and are in the public domain, so if GOLF Magazine thought my image of the course was better, why would the club care which one they used?
BUT, I was never going to sell my photos to make postcards or calendars or playing cards or anything else which would generate a large sum of money. How would you feel if you were Mike Keiser, and you saw a deck of Bandon Dunes playing cards, with poor quality photographs of the golf course, which were unauthorized and for which you weren't making one dime?
I'm much more careful about that now, because as we all know once a photo makes the Internet, anyone can use it for anything.
