leica iiif shutter test 25th sec

This is one of a sequence that I took with this roll to check that the shutter speeds were working correctly, and to get more information into my head so that I begin to do the iso/shutter/f-stop/available-light algorithm in my head; (hereinafter, "The Algorithm").

leica iiif shutter test 25th sec, originally uploaded by Pig Sty Avenue.

This one's a 25th of a second, and there's no camera shake, (I think there's a tiny bit of fuzziness at speeds 15th, 10th and half, and a lot at B, about 2 seconds). It means I can get away with 1/25 (and two deep breaths) which would surely be more than enough in even dim light at 1600, f2 or even f2.8.

This was at 400 iso, f2.8, full spectrum light.
