An anonymous contributor to Hackaday has devised a new analogue film format called the RA-4 cartridge, made from a 3D-printed cartridge system that fits into the back of standard 5 x 4 inch cameras, and holds a long roll of RA-4 colour print paper.
Developed in conjunction with a modular developing machine, the RA-4 cartridge can deliver more than 100 shots per roll.
The developer intends to release files to the public as sales milestones are reached, rather than charging a premium for the innovative design, which represents an exciting development in analogue photography.
Such creativity in camera use and development demonstrates that there is still fun to be had with analogue film, as well as useful techniques such as reversal development of RA-4.
