Noticing the "made in the czech republic" mark on the Orca 110 box, I went out and shot with the 20-40mm lens on my Pentax Auto 110
I processed the film exactly to the instructions in the Foma Reversal Kit, with no deviation besides using a hardening fixer for the final step
Here are scans, and then 100% crops, because I was really impressed at the resolving power of the zoom, and the film!
The results are so nice, I almost prefer it to the negative results I've gotten, seeing such tiny reversal film is magical.
Try it out for yourself!
