Let's say, hypothetically that I am illustrating the photograph of an iconic person and have obtained permission to use material from one of their descendants of some musician to use material from them in a design, but the photo is owned by some else. I'm not using the photograph, but drawing a vectorised image from it. Do I need to obtain copyright permission from the copyright holder of the photograph then, or not, or is it a grey area?
