This is my last roll shooted for the subject of Photographic Technique, into the first year for the HNC of Photography in the EASD Pablo Picasso. We just used a slide film to test the crossprocess results. Unfortunately we could not find not expired chemicals and we had to ask to a local lab for the developing. I had some problems to focussing with my Jupiter 37A, it is only useful for portraits. I used as well many times one of my old Helios 44-2. Developed in Foto Artús and scanned by Magenta: magentaonline.es/ I have to admit that only a pair of pics are worth... You know.
