Not an open and shut case

I was giving a lecture at the Museum of Space History (Alamogordo, NM), and someone took this wide angle shot. The camera they used had a sliding slit screen instead of a mirror that pops up and out of the way or an aperture that just opens and shuts. The result of it was that, because they took the picture right at the moment of slide change in the talk, the slide on the screen and its reflection in the back window show two different slides. Not sure what camera that was, but I found it interesting that that can occur. Basically, the left side of the picture and the right side of the picture were taken at two different times - a microsecond apart, but just enough to catch two slides on the screen in one picture.

Timing just right. Slit shutters can do that and in some cases, like a runner going left to right, you get two of the same leg with maybe a blur in the middle.

Swing lens cameras do that.
Also circut cameras.
Theres a great tradition with using circut cameras to do large groups of having the same person appear on both ends of the group. Person should be a good sprinter.

Focal plane shutters on DSLRs travel across the frame in about 1/250 second. My speed graphic had a focal plane shutter in addition to a leaf shutter on the lens. I never measured the time it took to cross the focal plane but it was probably on the order of 1/20 second.

One of the brands was Widelux, I had the Russian version, if I remember right it was a Horizon. You have to be careful loading the film because it goes into a curved slot. I remember because on the first roll I didn't read the instructions.
