Last Fall, I ordered a new custom-made pinhole 6x6 camera (RealitySoSubtle 6x6) and a 10-pack of Washi 120 film (an orthochromatic emulsion on very thin washi rice paper, ISO 12-25 or so). I've not had a chance to use either until this weekend when I was off to an annual event with friends up on the Mendocino coast.
Of course, I had no experience using the camera or processing the film.
I exposed at ISO 10 to get a baseline, estimating that based on an f/16 setting on the meter I'd need about 75x more exposure time for the pinhole's f/137. It's an ultra-ultra wide FoV ... about equivalent to 20mm on a 6x6 frame.
Open tray development is recommended for the film ... but I have no facilities for that. It's too thin and fragile for a standard spiral-reel tank. So I bought an old Kodacraft 120 roll-film tank with the apron style separator. Some interesting developers are also recommended for the film, none of which I have either. So I just mixed up my standard soup of HC-110 at 49:1 and used my standard 8 min @ 70°F to see what I'd get. Here are four images out of the 11 exposures I made:
I am pleased that I managed to get four images out of the playing around I did...
The camera worked very nicely.
The film was very underexposed off the highlights, and most of the highlights were blown out. I think the solution there is more exposure plus longer development time at the same dilution. I'll be doing some more experiments ...
enjoy!
