I recently finished up shooting various interiors at a large commercial office building park. The architectural firm that hired me will include my fee with theirs. One of the other partners in the project, a development firm, will want usage rights to all the shots, and the architects want that fee included in my invoice. I've rarely had another party want to purchase rights; just a flooring/tile company in one case. Is there a standard rate or percentage in the industry for downstream usage such as this? There are 45 shots, and the rights would be non-transferable.
Thanks,
Merrill
