Trying trichromes with my iphone and my great granddad's old Kodak filters
I have Wratten filters A, B, and C5. The first one is the raw image that I mixed up in GIMP, and the second is color graded to match roughly what my eye sees. I took three photos with the filters and lined them up as best I could, and then converted those to monochrome and recolored them as their respective channels.
