Perhaps I didn't ask my question properly. I understand the difference bewteen physical ownership and usage rights. I strongly suspect, however, that the model in question does not. Before I speak to her about it, I need to know how her usage would be classified in this particular context.
I hold the copyright to the image. I have a model release from her. There is absolutely nothing in the release that explicitly provides for any rights for her to use the image. The image in question was used in a calendar. As a curtesy to her, I gave her a copy of the final image as printed.
If she had framed it and stuck it on the piano in her living room, that would unarguably be considered personal usage and I doubt that any sane photographer would have a single ill word to say on the matter. On the other extreme, if she used the image in an ad campaign, that would be commercial usage, and since she has no commercial rights to the image it would be a definite infringement.
Commercial usage aside, models do collect tear sheets. She could grab a copy of the calendar, tear out her page, stick it in her portfolio, and show it to anyone that might want to book her for a shoot. So the first part of my resubmitted question is: Are there generally any issues related to models showing tear sheets? Can they ever be restricted? Do they need explicit rights, or is there anything implicit?
Second, would posting the image, along with others of her done by other photographers, on her MySpace page, along with words to the effect of "I'm a model, please hire me" qualify as the on-line equivalent of a tear sheet, i.e., self-promotion, or is it commercial use?
Thanks again for your time.
