I noticed the Auto option in the WB dropdown for the first time the other day. I've literally never used it. However, I found for indoors it was doing a better job that the AWB on my 5d2/5d3 so I wanted to use it.
However, while it's close it's a little blue to my eyes so does anyone know if you can tweak the settings, like you can with most cameras, to nudge the chosen WB to say +100 or +200 kelvin?
If not, how would I go about requesting that as a feature?
Nope. Can't do that.
The best you can do is use Quick Develop to do a relative adjustment on a
selection of files.
