I had issues loading my film again in the C3. The back didn’t close properly and the counter reset itself after only two images. I thought I had figured out how far to turn the crank per image, but it turns out I was way off.
I took notes for six images, but in reality, only got two frames. One at the midpoint of the film strip and the second right at the end – clipping a third of the image. Live and learn.
