suppose there were other uses of a matrix film — what might they be/ have been. Would they provide enough users for an emulsion run.

— this question was one raised in earlt 1990s, then again in 2K.

The question remains open.

pathways to panchromatic matrix film:
-- orthomatrix resensitized to tricolor set
-- factory sensitized tricolor set, as if they were pigment tissues
-- 

this is a shorthand post… another open question post is: why can’t a group gather resources enough to build products.

I don’t know that I have the correct answer, but I do have an answer .
