[Frameworks] black mask on colour print film

[Bernd Luetzeler]

Dear Jeff, dear Scott,

thanks for your ideas!
The problem sounds so simple, but since the mask is changing from left to right between cuts, it’s quite a tricky thing…
So masking the projector wouldn’t really work, but the fogging idea might do the job, let’s see…

cheers

Bernd

These are commonly used to mask the image to 1.66 or 1.85.  Of course this is easier if you are only screening at one venue, since projectors will vary, and also the aperture plates are often custom-filed to deal with any angular displacement of the film and screen (I am blanking out on the word here — it’s not parallax but it’s like that.)

Perhaps there’s an ink or paint but getting a good clean line (if that’s what you want) will be difficult, and it will flake off in use.  Then again that may be desirable in your case.
