Don't bother trying to fix a constant manual exposure unless you're
shooting more than once every five seconds - the conditions during the day
will change enough to make it "flicker" anyway, you might as well let the
camera decide what's best.

I've tried time lapse photography using the built-in timer on my Minolta A1
camera, but consistance of exposure is a real problem: the resulting video
flickers a lot, which is very distracting. Ideally you want the same object
to keep a roughly constant brightness in the phot as the lighting changes
(eg as a cloud goes across the sun or the sun sets).

I've noticed that professional timelapse videos don't flicker as much. What
do they do - do they have software which post-processes each frame in an
attempt to compensate for gross changes in exposure as the lighting changes?
