'm not so sure that I agree with MetroGlamour on this one, although his been around longer than i. I would think that if the photographer has been compensated and you have a signed release in hand giving you permission and rights to those pictures, I wouldn't think that SG would compensate him again.
I suggest you submit that question to Rambo: she is the photographer and model coordinator and should be able to get you an accurate answer. I presume that this photographer is not a Photographer Hopeful on this site ... ( Hopefuls are not allowed to charge for SG sets, unless I was mis-informed).
This photographer is not a hopeful but he agreed to the SG terms when he said he would do my photos. if you read my previous blogs you will see. I will message Rambo. Thank you guys!
