View Full Version : Custom WB on AWB?
Gustavs Repse October 21st, 2010, 09:10 AM Hello.
I have one question about , on which White balance setups i should take the picture for setting a Custom White balance for video?
Will i get the same effect from taking a picture of a white page of paper, in the environment I'm shooting, on any White balance setups ? AWB/Night/shady/tungsten etc?
How do i go about it ?
I am usually using AWB
I think Picture style shouldn't matter in setting a Custom white balance.
Aaron Courtney October 21st, 2010, 11:10 AM hey man, i just finished another doc and achieved the best custom WB by holding a gray card in front of the cam in the subject's light, snapping a pic, and using that for white balancing. I mean it was balls on perfect (exposure was too).
Gustavs Repse October 21st, 2010, 11:15 AM But on what WB you did it ?:)
AWB?
See, you get a wherry different image from each of the WB presets. So i am guessing for Custom white balance i have to use AutoWB, which is most neutral .
But i am not sure about it.
Ted Ramasola October 21st, 2010, 11:34 AM the manual said you can use "any" wb balance setting when taking the photo. For me I use AWB for taking the photo for custom WB.

Thank you.
Aaron Courtney October 21st, 2010, 08:37 PM Gustavs, i don't think it matters because the cam will set the white balance irrespective of what the lcd shows you. to prove this i snapped a few pictures with deliberately chosen incorrect white balance settings (like tungsten in indoor daylight scene - which made my white walls blue, lol), and after loading the pic, the custom WB imagery was perfect.

Aaron Courtney October 22nd, 2010, 11:02 AM not really, the motto IMO is to custom WB every shoot with a Kodak gray card using whichever preset you want while snapping the pic required to properly set custom WB.

Thank you guys.
John Vincent October 25th, 2010, 09:14 PM Ant one know of a good place to get a plastic grey card? Paper ones will die as soon as I buy them...

(not plastic, which you would not want due to reflections)
i think mine says $5 (purchased 30 years ago) inflation sucks, literally

Lastolite EZYBalance Grey/White Card - 20" LL LR2050 B&H
I got one at my local camera store a few years ago that collapses to about 5" diameter. It's pretty sweet.
