Re: digital cameras
Got the SLR (Nikon FE2 with solenoid trigger on the motor drive), but I am
trying to do something that has a low probability of getting caught on
film, (e.g. shoot hundreds of frames to get the one).
Video cameras do not have 100% probability of intercept: The shutter
duration is a fraction of the field time (which, is in turn, half a frame
time of 30 fps), a fact which is used on some interesting aiming aids (they
use a laser and just turn it on it when the camera isn't looking, between
frames). Even broadcast quality video cams are still interlaced, and, at
best, 250 or so lines vertical resolution (at least in the US with NTSC).
HDTV video cameras are better on resolution, but not on speed or timing,
and really, really expensive.
Nope.. I'm just looking for someone who has had practical experience with a
digital camera in the under $1000 range as far as external triggering (very
few digital cams have this), settable exposure (also somewhat rare) and the
consistency of timing of the triggering.
