A black and white X-ray cine film originally developed for the diagnosis of lung diseases.
As it has no antihalation layer, it offers an interesting diffusion effect and a beautiful fine grain.
According to Wash, it is essentially comparable in development to FP-4+.
Orthochromatic Washi film has a sensitivity of 100 ISO when processed in Tetenal Eukobrom positive developer at 1:1 dilution.
Washi materials are sensitive to the blue end of the light spectrum. However, they are also insensitive to the red end - which means you can develop Washi films under red light (> 545nm). Further, you process them as conventional black and white films.
The special Washi films are not produced by hand, as is usual with Washi materials, but in classic industrial conditions. However, they were not developed for conventional photography, but for use e.g. in photo machines, as röngen films or were designed for military purposes.
It was only later that Washi adapted these films into standard formats for use in conventional cameras.
