fluorescent flicker... at DVinfo.net

Leslie Wand · December 1st, 2020, 11:37 PM

the older i get (and the more retired i am), the more i forget...

have a 'cold room' shoot. place is brilliantly lit with fluorescent lights, white walls, etc.,

iirc, flicker reduction is turned on in auto mode by default. (i'm in pal land), and, iirc again, did quite a good job. i'm just wondering whether i should be looking at ecs and fine-tuning, and if so:

a. should i be turning flicker reduction off?

b. believing what i see on the lcd / viewfinder?

i can, of course, correct in post, but prefer not to.

tia

btw. it;s a remote location so i have no way of checking out before i arrive.

Hi, Leslie.

Given that "fluorescent" has taken on such a plethora of meanings fire - wise since the good 'ol 100Hz days, I'd go for option (b) with the proviso that "lcd" was at least HD 27" in a well darkened room and a properly calibrated set of MK I eyeballs, subsequent to "test shoot".

Regards,

CS

well, in passing interest...

turned camera on, white balanced, and out of curiosity, shot some test footage. no flicker at all. mind you, it was a university cool room whose lighting was designed to be as close to daylight as possible.

i did play with shutter speed, clear scan, et al, just to make sure, but out of the box looked great. in post it looked just as good and my xrite card was as close to spot on as could be expected...

have a great new year one and all.
