should it?
In the US, any shutter speed 1/120th or faster is going to be an
issue. It's the flicker of the lights, not the shutter, that matter.
My point was that if the shutter opened completely the color balance
would be consistent all of the way across, or at least that the effect
of it opening and closing would be far less noticeable than when it's
just a slit going across the sensor.
You are right that exposing for an integer multiple of the time of half
a powercycle (1/120 sec) would more accurately negate the effects of the
flicker of fluorescent bulbs.
So, to minimize the effect of the flashing of the fluorescent lights:
1/120, 1/60, 1/40, 1/30, 1/24, 1/20, 7/120, 1/15, 3/40 ....
1/100th of a second in Europe.
