Forgive me if this has been answered before but I’ve searched for an answer and haven’t found one. After developing my photo, the paper sticks to the back of the camera, and If I’m developing while out and about, I’m not sure how to get it out of the camera without mangling it.
I’ve mostly been developing at home and find that running the developed print under water unsticks it from the back of the camera, but this doesn’t work away from a faucet.
I’m really enjoying my camera!
A Little late here, but I use a guitar plectrum that's nice and firm but soft texture, like a Tortex one, that I had heated up and popped a bend into the end section to allow me to lift while there is some water in the 'tray' still.
As others have mentioned, I normally flood the camera with water under a running tap until bubbles get underneath and lift the print. This is less helpful in the field, but fine if you're in your bathroom doing the processing! On some other systems (Paterson Orbital, for example), people sometimes roughen the surface with a dremel tool to break the surface tension beneath the print/film and make it less likely to stick in the first place. I haven't tried this on the Pinsta, though.
How to remove the paper/film? Carefully!
Joking aside, sometimes you do get a print that is really difficult to remove even with the removal tool. As the emulsion surface itself can be easily damaged, if the print doesn't come out easily I add more water back into the tray to try and break the suction effect. You can use the tool to try and slide the print back and forth a few millimetres, whilst lifting, again adding more water if needed.
If you don't have the removal tool, or a last resort, I might use a knife blade, other people have said they use a tooth pick (probably a safer option), to try and lift the edge. In either case there's a risk of slipping and scratching the surface. I did see someone, I forget who, place a thin strip of plastic under the print when loading it, to use as lift tabs - that's quite an interesting idea, as long as you remember to leave the tabs out, and not laying over the print!
You can use a toothpick or similar narrow 'tool' to get under the edge of the wet photo and lift it out enough to get ahold of it.
Or ... Some pinstra kits/cameras come with a small tool that's got a suction tip for just this purpose. And ... I usually place my photos developed in-camera into a small tray of water (even in the field) to rinse them more. I will sometimes just turn the camera back over and shake enough for the paper to fall out or move it enough so I can grab the edge.
