Geometry. These are mostly geometery. I’m really fond of these pictures because of something weird. This lens got stoled! The pics were taken with some unusual equipment. The series was shot with a Topcor 100mm lens. Topcor/Topcon equipment was a special kind of stupid as engineering. The aperture controls were built into the camera instead of (as normal) the lens. Everything that you shoot is wide open–about f4. During the shots I had to hold the lens manually in the camera body. LENS… NOT ATTACHED!
