I'll be 56 in about a month. I didn't begin to photograph well, either technically or aesthetically, until I was 53.
This had nothing to do with my age. I ran into mentors in 2002 who "turned on the lights". This could just as well have happened at 22 as at 52. In fact, a photographer I know who was 22 at the time took the same workshop I did. He seems to have acquired the same gnosis I did even though we differ in age by some 30 years.
I've come to believe that it's never too late to do anything you care about.
