David Dubnitskiy - Renault Driver with EXTRAS

No, haven't seen NUDE with David Bellemere, but have found it in Vimdeo, so will give it a watch. If you have a close working relationship with a model with establiahed trust, you have already established boundaries and what is OK, or at least there should be. But that longterm trust relationship might not come across in a video, so it needs to be spelt out for the camera, and probably onscreen behavior modified, so as not to give bad examples or impressions of how to work. I don;t know if that's the case here.
Matt Granger has covered this issue in detail in his tutorials, there was a great discussion in on of his more recent ones in Hong Kong where he's based atm. A professional hands-off approach protects not just the model, but the photographer. You cannot assume consent, nor that the model will say anything about being made uncomfortable, esp in a well-paying job with a respected photographer.
