photo from week 168 - Stereo Puck

grain store, a photo by pho-Tony on Flickr.

This really is a very simple camera, there is no focussing, no choice of aperture (though later versions had Waterhouse stops to give 3 apertures), and single shutter speed plus "B". This was taken in a fairly dimly lit corner, I put the tripod on a camera, and held a black card in front of the lenses while I opened the shutter, then once I'd stopped touching the camera and risking moving it, I used the card as a shutter to give an exposure of approximately 20 seconds.
