Here's a shot of a little camera I was trying to sell. It was purchased in the early 2000s for $60, and I was lucky to sell it for $30. It's sad how value depreciates as technology improves.
Anyway, I thought I should try to prove in my product photos that the camera, or at least the electronics, still work. It took took a few failed attempts before I managed to get a proper exposure, and sync the shutter on my DSLR with the flash of the little film camera.
