DetailsWashi Film is a black and white photographic film developed from traditional paper, Washi. Made for centuries in Japan, this paper combines just the right physical properties with a unique aesthetic: strong, flexible and transparent, Washi is the ideal medium for creating a hand-crafted photographic film.
Washi film has a basic sensitivity of 25 iso when process in Tetenal Eukobrom at 1+1 dilution (you can reuse the solution for several rolls or sheet-film).
This Film is orthochromatic: sensitive to the blue end of the spectrum while being relatively insensitive to the red. This means that Washi Film can be handled under a red safelight (> 545nm).
Easy to handle and develop, Washi Film is available in conventional photographic formats: 120 and 4x5. It is processed in normal black and white paper developer. As an handmade product, Washi Film must be carefully clean with cold clean water to ensure optimal conservation of the negative. The negative can then either be scanned or printed by contact or with an enlarger. Only traditional prints or transparency scan can reveal the full potential of Washi negative. Simple scan would give an overexposed veil over the picture.
Washi must be processed under safelight in open trays:
1. unroll the film and then separate it from its protective paper
2. fix a flat clamp at each end of the film to handle it safely
3.dip completely the film in clear water to give it a flat shape
4 immerse it in the developer until complete stabilization of the negative
5. rinse the film in a tray of clear water, do not use stop bath
6.gradually immerse the film in an ordinary bath fixer
7.once the film soaked with fixer,hang it for 3-5 minutes
8.rinse several times the film in a tray of clear water for at least 5-10 minutes.
9.suspend the film and leave it to dry.
10.Once completely dry the film tends to curl, cut it into equal strips that you can place under a weight in order to flatten it.
