140 degrees of usable image with flat film pinhole camera
Well, I've made it. Mainly, because there were people demanding some kind of proof.
I've posted results (cropped positive, not cropped negative - clean and with some comments) on my (non-profit) blog:
I've commented there as much things as I could.
I've made solarigraphy. 23 mm focal length, over 18 cm of image diameter, within 12,8 cm diameter image was quite good (slight vignetting).
Paper was taped flat in thin box.
This gives 140-150 degrees camera with flat film.
The materials were cheap, the construction was fast, the camera in fact is a failure. But it works.
