Re: Applying white balance afterwards

Sounds easy enough and thank you for providing all the detailed
information.

Once the file is imported into ACR or NX and WB is adjusted, can this
cause the Red or Blue channels to clip using this method? I guess
what will happen once proper WB is applied?

Yes, this can happen at the default ACR or NX settings, but, of course, no information has actually been lost. At that point you simply use Recovery or Exposure to bring things back into line and whatever other controls you need to make a good print of it.

Remember also that the ACR zero Exposure setting is actually +0.5EV -- for some reason, ACR applies a "BaselineExposure" setting to all cameras, and the D300's is +0.5. So, if you can remove all evidence of "clipping" with a reduction of Exposure by 0.5EV, you really had no clipping in the first place.

Also, how do you usually determine your WB in order to get accurate
or pleasing color?

Dave, I use the WhiBal gray card, either including it in the shot (in a spot that is either very small and inconsequential or able easily to be removed with the clone tool) or taking a separate shot of the card in the same or similar lighting. I find the WhiBal works extremely well.

Thanks again!

You're welcome.
