Washi F B&W Negative Film 135-24 (35mm)

Washi Film F is an ISO 100/21° ISO black and white X-ray film originally developed for the diagnosis of lung diseases.
It combines the aesthetic quality of X-ray film with the physical quality of classic camera film, making it possible to convert it into 35mm film.

Since this film does not have an anti-halation layer, it offers interesting blooming effects.

According to Washi, it is essentially comparable to the FP-4+ in terms of development.
