Found Image #1
This Kodak Brownie Reflex 20 was $15 on Craigslist. The price seemed high, but upon inspection, the camera already had a roll of exposed film in it. So I thought, what the heck, film doesn't come any cheaper than that!
The film is 620 Kodak Verichrome Pan exposed (most likely) sometime in the early 1960s; developed in Diafine for five minutes each for both solution A and solution B; scanned myself on an Epson v700. (Some adjustment of to get it to scan well, but no other correction or post-production.)
My current hypothesis is a child owned the camera, shot the roll on a vacation out west, and never got to the next step.
Final budget tally for these images:
Processing (DIY): $4
Scanning (DIY): $1
