So if I want lighting around 400nm on the light spectrum, can I combine lights that have peaks at, for example, 380nm and 420nm and get something "in between"? The lights are addiditive, right?
THe reason I'm asking is because I've discovered a powerful UV light source for collodion that has a narrow peak at 360nm, while collodion's sensitivity is 380-420nm, so I want to combine my UV light with some blue light to get an "inbetween" nm. Or at least I'm thinking about it.
