I just assumed that there the revival in direct positive paper, espcially by Ilford, was because of their involvement with The Impossible Project- but having thought about it, I guess that the technology might just be a bit too different to compare. . .
Btw, has anyone ever used the direct positives to enlarge slides? It would be amazing to be able to have both a slide and a traditional fine art print of the same scene without having to make an internegative!
