I shoot for an architect who, along with the contractor, has a concern about the photos (which I took) being used without permission. Basically, two contractors were involved in the project. The first contractor, Contractor A, was replaced by Contractor B who eventually completed the project. (I'm not familiar with all the details but I understand there was "mis-information" with Contractor A so he had to go.) The concern is, if Contractor A finds the photos on the architect's website, there's no stopping Contractor A from using and showing the photos to his prospective clients and claiming the project is his. Or is there? I mentioned watermarking to the architect but I thought I'd ask here to see if anyone has encountered a similar situation and what precaution, if any, was taken. Thanks a lot.
