So bowl, if I understand correctly;
Legally, it's not rape. Because she didn't know, as in had never met, the man she had sex with. The fact she had a photograph is not classed as knowing or having a relationship of any sort with either the person in the photograph or the person claiming to be the person in the photograph.
Therefore, legally, the photograph is irrelevant, and the case is treated as if she met a stranger, allowed herself to be blindfolded without seeing him, and consented to sex.
If he had sent the young model to meet her and blindfold her, then swapped and had sex with her, then that, legally, is rape.
