I'd just like to know how 'you' feel about a model bringing an escort. The good, the bad, plusses, minuses, etc. I've had some models bring one, and others not. Again, I'm not shooting nudes, or implied nudes, so it may be a bit different when shooting that type of scene.
1) I won't let another one in a studio type setting, especially when there's another photog. in house. I've seen too many of the shots where the model is looking away from the camera, even when I tell her to make contact with the camera, because her friend/other model is trying to change, or talking with the other photog. etc. So, no more!
2) On location...first time meeting me...yeah, I'll allow it. Second time, if I work with the same model...and I felt that the escort wasn't a bother, I 'might' let her bring the same person.
3) Boyfriends...no. That is just too big of a hassle...and can get out of hand 'way' too fast...and I assume moreso with nude/implied nude types of shoots. I had one guy walking around the area...and kept getting in the shot, despite my asking him to sit still in one farkin' place. But no...he just had to get up, walk around, stretch...bah. Done with that.
