You do not have to work in a Black Room. A Cheap (~$200) generation 1 IR manacle takes a bit of adjustment. But I use one all the time. Worst part is- distorted depth perception.
Denise- Not to be cynical, but "almost there" can be much longer than "halfway there". You and I are working with different systems. But I hope that, once you get "There" you will publish info on TLF.
Ian, If you know the dye system of IR imagesetter, just add some erythrosine and you have a panchro emulsion. No?
