RE: [APML] Konica 400 - First phase photographic tests

["Chris Schur" <cschur@therim.com>]

Stuart, the exposures were 5 mins, but I ran the film through the camera,
all 24 exposures over a 6 hour period.  Its possible that the timer could
have done 10 min exposures, but I was outside for at least the first few,
and it seemed to do 5 with 10 between new shots.

Chris, the webpage says you ran for 6 hours at f3.5 (9pm to 3am) but the
photo data at bottom says
5min. With the Zenitar I don't think you could get stars that trailed in
5min so was it really six
hours though?
