If used as a regular 400 ISO black & white film, there is nothing special about it. However, it is one of very few infrared light sensitive film stocks out there and it makes it quite special! With an IR filter, it's great for dramatic landscapes or Giedi Prime-like eerie portraits. The caveat is that Washi Z is similarly priced to a roll of Rollei Infrared and it's only 24 exposures while Rollei is a regular 36-exposures film. It's definitely worth giving it a go but I'm not sure if I'd use it for regular work.

Attached photos are:
1. Shot with Washi Z with no IR filter, exposed at box speed.
2. The same shot taken with a 720nm IR filter, added 5 stops compared to box speed.

I shot this film with a red filter using a Nikon FM with 55mm micro lens. I photographed dead trees that have fallen due to cliff erosion on a beach.

What a mixture! Infrared and nature photography together. I quite liked the results. Might do it again.

Interesting company. I mostly shot this with red filter, to get "the look". Pictures are nice, especially paired with nature photography. Manual cameras only.

Took this film to Knoydart in the highlands of Scotland, UK. Many shades of green lent themselves well to this film.
