    I very much agree with Randy & Barry on this Chris, both cameras and images are great.

    I made this camera a couple of months ago out of scraps of White Cypress decking timber that I couldn't see go to waste. Size is 5x7, pinhole size 0.4mm, pinhole-film distance 100mm, speed f/250. The pinhole is on a movable panel that allows +/- 25mm shift, most useful in vertical compositions. Full rise was used in both of these pics. Film was cut down Kodak 5x12 dental panorama x-ray film (exp. 2009) developed in Pyrocat HD. I do like this film.

    Love the camera and the photos. That film works very well.

    Question: how do you judge the shift with a pinhole? I would expect the image on a screen to be far to dim to even see it.

    It’s pinhole, there is no GG for viewing. You basically point the camera, or shift the pinhole by best guess.

    Steve's right. I have sighting dots - small cut down nails with painted heads - to indicate where the camera is looking. But they are only for the pinhole centred. When the pinhole is shifted I just have to hope that everything is in the composition. Fortunately 100mm on 5x7 gives a somewhat wide angle view which allows some room for error. In the shot of the tree I gave the fill rise and aimed accordingly and got the composition I wanted.
