Thanks for your response Charles. The designers do not have exclusive rights nor did I transfer the copyright. Builder will use the phots for promotional purposes: his website, Houzz site, Instagram, print ads, etc. for unlimited time period. No editorial submissions. The other part of this equation is that we only shot half of the House due to the homeowners time constraints. We will go back for another shoot to do the rest of the rooms. The designer is hiring me for this, but the builder will also be interested in these additional shots. Should I continue as I am for the first half of the shoot charging the designer my regular fee and the builder per photo for usage? Or work out some other deal up front before the next shoot for some kind of shared fee? Thanks for any advice as I’ve never had to deal with this situation before. As a side note, I’ve worked with the builder before on his other homes so he is familiar with my regular shoot fees.
