    Snow day project

    I got inspired by JE Piper's article on and made a lens addition to an old pinhole camera. 90mm focal length and 90mm in diameter means its an f-1. Plan to do in-camera cyanotypes like these,

    Snow Day Camera Results

    This is the cyanotype negative and inverted positive shot in my 90mm, f-1, 4x5 camera. I coated Somerset paper with Ware's cyanotype and exposed at sunset on my roof. Still need to adjust the focus a little but this test shows it works. Negative scanned directly after shooting from the printed out image.

    You are already close to those examples you pointed to in the other thread! Well done! I was wondering how your lens would do, but it looks very promising! That's something of a "black sun" solarization, right?

    Wonderful! I love the look of the positive image, and the idea of a cyanotype negative is ingenious, offering yet one more alternative against the day when commercially made silver gelatin media might disappear.

    What was your exposure time with this fast lens?

    I got home late after running an errend but since it was still light out I went to my roof deck and left the camera out for an hour even though the sun was setting. I probably only got 5 minutes of sunlight until the sun went down. The negative was a bit thin, thats why I didn't bother processing it and just scanned the printed out image. I adjusted the lens and think I'll have a slightly sharper focus for tomorrows test.
