My guess would be that if available they'd be quite expensive, meaning an
outlay for a process you're not entirely sure would work. But theatrical
lighting gels in very similar colors would (I believe) be much cheaper.
The companies put out sample books, you might borrow a tripack for color
sep from someone & find the closest by comparison.
It's also possible that you could simply BRACE the camera. That is, fasten
it into position so it wouldn't move.... or at least try that for
starters.... especially since you can register the seps by eye... noodle
them in case there's been a bit of wiggle in the position of slide holder.
