Another self taught guy here but I did get a good break. I walked into a studio one day and told the photographer/manager that I wanted to be a professional photographer. This particular studio only shot female studio sessions. I had known about the place for awhile because my wife had had some shots done there a few months prior.
Anyhoo, the manager was getting ready to leave the position (she was preggers) and because of my business resume, I was qualified to "run" the studio end. I met with the owner (who I immediately saw his personality - a true middle aged pervert (who consequently never shot in his own studio)) and we talked "photography" (he and I shared a trait: we would get old fashion mags and rip out interesting poses, lighting, facial expressions, hand placements etc. and keep those tear-outs in a file that we would study and study and study. Mine were things like Cosmo and Vogue, his were Penthouse and "wack-mags".).
They took a chance on me in the studio... there were 2 identical setups and I was the 4th shooter (soon to be the 3rd when Camille left). The other photog's and I learned from each other and I am very grateful for the shot.
I ended up leaving there when my first daughter was around 2 months old for basic family reasons. The job paid well but I didn't think [being a new father and husband] that I needed to continue shooting in the style I was. That studio was known for boudoir and nude photography. I was shooting 4 or 5, 2-hour sessions a day and towards the end, most of my clients were wide open by the end of the first session.
It was the most technical work I have ever done. I think I can shoot with the best of them in the studio but, it wasn't worth the risk of getting tempted.
