Wondering if someone can help me.
I have 81-12 polaroid processor with 81-09 tray, unfortunately the film holder is an 81-05 which doesn't appear to be compatible.
Is there a way around this to process my polaroid film (impossible project of course)? Or do I need to buy an 81-06 film holder?
You can use the 81-05 holder in that processor. Just don't use the tray. The 81-05 is a little more finicky (which is why they invented the tray and the 81-06), but I get perfectly good results with it.
The impossible project 8x10 film is actually packaged very much like the old Polaroid film. There is a negative in a black sleeve, and a separate positive, or receiver sheet. The only difference is that the positive sheet is transparent, not opaque white like the old Polaroid.
Load the negative in the film holder and expose it just as it says in the instructions for the 81-05. Sliding the positive into the film holder afterward is a little tricky because it is not as stiff as the old Polaroid positive sheet. It's frustrating at first, but it can be done and after a few shots you get the hang of it.
Clean your rollers after every shot, the impossible film is pretty sloppy.
