I am not sure if this was the first or second sheet film pinhole portrait I ever did with the below pinhole camera. The negative came out a little thin, but still made a nice contact print, and also comes out fine when scanned and processed digitally. In addition I made pretty passable Cyanotype contact print from the negative. Because of the the fairly long exposure, portraits will usually come out a bit blurry. Surprisingly that usually does not detract from them.
The film was Kodak 4×5 Tri-X sheet film, and I had it loaded in a film holder. The camera was on a tripod. I think the exposure time was around 20 seconds.
