Well, by my calculations, if the volume of "dichro" was so much greater
than the paint (a few "squirts"), say about 10 times as much (?), that
means in effect you had a 20% solution -- wouldn't you say????
And if so, it doesn't count as 2%...
However, you don't say how far from the light source that 15 minutes
exposure was... Also a factor in actual exposure...
