Jeeesh, trying to find these on eBay is a nightmare. Either people want exorbitant amounts for 1 filter or it's a lot with all sorts of random gaps. Not to mention, there's no one way to search for them and find what you're looking for.
Question.... would using CP (color printing) filters for imaging be disastrous? I realize they're aren't meant for this, but rather for changing light sources, but I'm curious how noticable it would be.
Just a thought, and a bump.
Would love to get a lot of these filters from an APUGGer
