Sounds like something from Playskool! But it was actually my Dad's Kodak Retina I, a little Stuttgart-made 35mm folder with a decent Schneider lens.
Along with a 1948 GE light meter, a gift from my friend Roger Wesalo, I was in business. With a camera as basic as this one, I had to learn all the basics. I even had to get good at estimating distances (in meters) because there was no rangefinder - just scale focusing. So that lead me quickly to understand depth-of-field.
My college friend Ed Hollingshead took this in NYC in Central Park sometime in the fall of 1967, our freshman year at Stevens Tech in Hoboken. I used to poke fun of Ed because of his left-handed, East German Exacta SLR. Little did I realize then that years later, I'd be a collector of Commie Cameras!
