stupid question about white balance

[mantra]

Hi
i have a couple of questions

1) does the white balance in lightroom , acts like photoshop (levels or curve) white+black+gray eyedrops setup?
i mean to correct the colors often is enough to click on the black zone , the white zone and gray zone with a curve or a level
does it work like white balance

2) in lightroom is better click on a white zone of the photo or a gray zone to make a perfect (good)white balance?

thanks
have a nice day

A light grey is generally your best bet Giovanni. White with no detail is no good at all, and black's not usually much better.

1) well i did a white balance with lightroom every time finding a white zone without detail so i did every time wrong


2) about the photoshop ,i mean find the white zone ,find the black zone and the gray zone ,and use the 3 eyesdrop and click in the respective zone ,give the same result lightroom white balance selector?


maybe i did not understand well , but what's the meaning of white with detail ? white with noise?

thanks Victoria

You just want the lightest grey area you can find, provided that none of the channels are blown out. If your target area has no detail because it's blown, then you won't get an accurate WB reading. If it has no detail because the subject was smooth, then that's fine.

Chroma noise can also fake out the WB dropper, so you need to be careful of that too.

Yes Giovanni, blown out means overexposed and that there is no detail. This is what can happen to white shirts in the sunshine.
