Quick use of the search facility doesn't pull up any results for trichrome images. By that I mean colour images made from 3 B&W negatives each taken with one of Red/Green/Blue filters. Anyone tried it? It's a bit of a marmite subject I think but if anyone is interested I can share some of my trichromes. Mainly 6x7 with the RB but I have done 4x5 pinhole and a couple of 7x17" ULF.
