I got engaged to my wife when I was 23 years old. At the time her brother was doing wedding photography as a side job. I started helping him in the darkroom. He would bring 5-7 films from the wedding on Sat night that we had to develop and make the contact prints so the customer can order on Sun. We would start the work on prints in the darkroom (his kitchen:)) on Sun evening and finish around 3-4 AM Monday morning.
At 6:30AM we would go to work like nothing happened.
I was doing the second hand paying attention to the process until one day I got my first camera (a cheap plasticky Smena 4) and took my first nice family picture. I still have that framed on my wall today. That hooked me for life.
