Re: [Frameworks] 16mm in the classroom - projector noise!

NSCAD uses a similar plywood box with a window in front of the lens.
The difference with theirs is that instead of leaving one side open to
access the projector, they have a door on hinges... so you can open it
to load the projector and close it once things are running smoothly.
It does a pretty good job and reducing noise. They painted it black
so it looks a bit less sketchy.

You could also line the inside with a layer of foam, followed by
another layer of a solid material (even something as simple as
cardstock) to reduce foam bits from flaking onto film and to increase
noise reduction. the addition of those two inner layers (bumpy foam
and smooth surfac) would improve noise reduction immensely.
