Isn't gate jitter a problem at every step of the process? Acquisition,
transfer to working negatives, edited master, duplication,
presentation, etc (how many "transfers" are made from acquisition to
presentation?)?
At each step isn't the perceived effect the same as spatially
convoluting the image with a gaussian of some finite width? Seems to me
that even if you start out at 4000 x 2000 you'd be lucky to end up with
a perceived 1200 x 600 even with just a +/-1 "pixel" jitter at each
step though I'd expect +/-1 "pixel" is a conservative estimate.
Am I way off here?
