As a long time photographer with an interest in Fetish and Bondage, I have incorporated my photo skills with enjoyment of this activity. I think this is something anyone with a camera can do. Of course your subject must be willing to be photographed and you must agree ahead of time where and how the photos will be used. I think it would be very easy to get in trouble with this if you posted someone’s photo without their approval especially on a public site where they can be easily recognized.I found that I can take a lot of photos without showing the person’s face, thus concealing their identity.
Of course the person you take photos of may really enjoy having his or her photos shown to the public and they most certainly will want prints for themselves. I do this stuff at no charge, but I am sure you could earn a little spare change doing this if you wanted.
If you use a tripod and self timer, you can even be part of the subject matter in some of your photos. No use missing out on some fun just because you want to take photos. Of course if you get into the fun enough, you may forget totally about taking any more pictures.
