I had trouble loading the FP-100C film into the RB67 instant back. There are no instructions. I didn’t realise that the paper tabs you pull are not meant to go through the rollers. But there’s only one possible way to load the film pack: simple but counter intuitive.
So I pulled the paper tab which peaks out from the closed door, thinking it would tear and I would lose the entire pack, and out pops the bloody great big polaroid from the slot on the side. Unlike Instax film these photos are shielded with paper during the development phase and you can peel the photo away safely once enough time has passed (which depends on the temperature).
Very satisfying. Looking forward to getting some B&W instant film. :-)
