Craft & Design Photography & Video

P^2 captured this very awesome video of a DSLR’s exposure process –

First attempt at capturing high-speed motion. This is a Pentax K200D shutter, as seen by a K100D and a high-speed strobe. Timing is provided by a few lines of C bitbanging a PC parallel port (in DOS, with interrupts disabled, natch).

Stop action and rapid recycle provided by the “winder mode” on a Metz 45-CT5, with its 90 microsecond flash duration, and <0.5s recycle time for the hundred shots it took to do this. Acquired shot-to-shot "frame period" is about 1 ms, and this is playing back at about 100x slower than realtime. The K200D shutter speed here is 1/180s.
