Self taught from age 12 to 17. Then I majored in photography in college and ended up with a BA. Mostly I knew the technical end of things before college.
The degree was geared for working photographers with heavy emphasis on business skills. From there were 25 years of weddings and commercial work. All while holding down a full time career as a commercial printer for 30+ years. I was able to retire at age 54 with a very nice pension and benefits. Now all of my photography is for my own edification.
