The Loch-Lomo is a pinhole camera I built from an old Agfa Clack 6x9 box camera.

A pinhole camera is the most basic type of camera: a light-tight box, a piece of film or photographic paper, and a small hole to let light in. Pinhole cameras produce images like no other camera, and offer a lot of room for experimentation. They are also easy to make.

Some time ago, I thought I needed a shift (perspective correction) lens. But the original Nikon PC lenses are extremely expensive (at least for me, doing photography only as a hobby), so I bought a Russian Arsat 2.8/35 mm shift lens, which is much cheaper. Here is some data about that lens, including a table of how far you have to stop down to avoid vignetting.

What's the point of comparing two black-and-white films that are not available anymore? Somebody emailed me with that question several years ago. It was still interesting to do this comparison, and who knows when you might get into an argument between b&w photo-geeks and need a source to back you up?
