I'm starting to get confused about who actually owns copyright privileges to the images that are posted on the MLS. Our local area Real Estate Association seems to think that they do once they are on MLS. They even put their Association logo on the images posted to MLS. Do real estate photographers lose their copyright privileges once they're put on MLS and the internet?
Yes, I can see how you are confused. There is a lot of craziness out there about copyright. We have followed this problem here on the PFRE blog for many years and you'll find many posts and discussions on this subject. Here is a short summary of some of the answers to your question:
Over the past several years, we have been lucky enough to have attorney Joel Rothman as a PFRE reader. Joel is involved in litigating MLS copyright issues. Joel has helped us sort out all the copyright craziness from the perspective of photographers. This is a post from about 4 years ago that summarizes some of Joel's advice.
