Professionally, hmmmm. In the early 1960's, as a kid, I was playing around with a Polaroid, Can't remember the model, it was a hard white body. I sold one picture from that camera at a motorcycle rally. Happened to grab a picture of a guy on a motorcycle who was in the air sideways braking his arm when he landed. He bought my photo for a few dollars.
A year or two later, took and sold pictures at the school prom using a film 35mm of my dad's.
My first owned dslr film camera was a Konica I bought second hand from a fellow airman in the Air Force. This would have been about 1966. I like that camera a lot but had it stolen.
Went to Nikon film cameras starting with nikkormats. Did some semi-professional work, weddings, studio portraits, etc...This was in the 70's & 80's.
Kind of got out of photography until a year or two ago with my first DSLR, a Canon XSI. Not shooting professionally, just hobby for now.
