Sounds like something that requires cream. Maybe Poli-ana? Anyway, little experiment I've been working on, needs some adjustment. Ripped apart a Stellar (Diana clone) and attached it to a Polaroid back.
Main issue so far is shutter speed...seems to be too fast. Underexposed ID-UV, which I believe is 100 speed film. Not sure how to fix that, as I can't change the shutter speed on a Diana.
This was exposed for about half a second.
Now this is 667, which is 3000 speed film. It is slightly overexposed, but I could reduce the aperture maybe.
The goop side shows a bit more detail.
So I've taken it apart again. First thing I want to fix is the dark circle. I figure I can correct that by removing 15mm from the barrel and making the body 15mm longer. I'll be posting updates and a more complete 'story' when I get the thing working to my satisfaction.
