I answered "film 35mm SLR" because it was the option closest to the truth. But the truth is that I started in the late 1960s with Rolleiflex cameas—twin-lens reflex cameras.*
Rolleiflex - Wikipedia, the free encyclopedia
I used them because this is what the high school camera club had. In college I continued to use them because the college camera club had them, too. I think they were already past their prime at that time. They were fun to shoot with and may have been good to learn on. They made you think about what you were doing very deliberately—a habit that I managed to lose somewhere in the 1980s and 1990s when I started shooting with a 35mm film SLR that some automatic features. Had to relearn the good habits in this decade when I got into digital.
During that 8 years or so, I also learned to do everything else: roll film, develop negatives and make enlagements. Nearly all my darkroom work was with black and white. I only worked with color a few times before I left the darkroom forever when I left college. I found color to be a big pain in the neck at that time. The pro who worked for the college and with whom I worked somewhat closely (because I was editor of the yearbook and he helped us out a lot) had a MACHINE, I guess an early version of the machines they use now to process film at the drugstore. I was amazed and repelled by it at the same time.
I certainly KNEW about Pentax back in the day. I may have shot with a Pentax camera for a while; the college camera club had lots of cameras. But later on, the film cameras I can remember owning included a Ricoh SLR that was stolen, and the Nikon N65 that I still have.
