PWM would most likely present a flicker problem,
Also PWM usually has at least 200hz, which is cycles per second, so any shutter speed faster than 1/200s runs the risk of catching the flicker.
I need a way to know exactly what that shift is though,
I'm not sure what the TRIAC Dimming is
However, you don't seem to have as much of an interest in photography, I could be wrong
I was simply trying to get some friendly advice here.
Obviously coming to the most credited forums i know of for this topic was a mistake.
Quite a shame really, that we can't put our heads together and make it work.
I'm looking for a solution to a problem I already know of, not someone to tell me it's not important.
so, to me, no flicker is my choice above seemingly imperceptible flicker
