There is a thin line with some models as to what is modeling and what is adult services.
If you are appealing to advanced and professional photographers, don't expect to make a lot of money when it comes to glamour, nude, and erotic images. The ratio of aspiring models to good photographers is pretty much stacked against you. We know a lot of models willing to work for little or nothing.
If, on the other hand, you target the escort side of the house and say you will pose for nude photos, those losers will pay out the *ss just to see a woman naked. Don't expect to get good images, though, and bring along an escort '-)
The adult film industry is a totally different animal. If you can hook up with the right people, you can make a lot of money doing porn films. Two or three of the models I have worked with have done very well in that industry. Problem is finding the right people. Unless they have contacts in the distribution side of the house, the films will never go anywhere, no matter how sincere they are at trying, or how well the films were shot.
Model here is Sarah Jade. She can give you a much better insight into the adult industry than I can. I shoot Gothic/Fetish art images, but still run into adult models who want to do more artistic images.
