In the 1970s, American inventor Edwin Land pioneered the instant camera, andPolaroid’s “pack film” cameras became incredibly popular.
These used a positive print process in which a negative was made in the usual way, but the unexposed silver halide was transferred to the photographic paper to make the final image.
This process still fascinates camera enthusiasts and hackers, and reader Jenny List has taken it a step further, delving into the patent archives to find out how it works, and what might be possible to re-create today using 3D printing and DIY hacking, as well as exploring whether it would be possible to load modern instant film sheets into a vintage pack film camera.
