Merry Christmas and Happy New Year to you and yours as well!
Thanks for the kind words about the photo of my dad. I shot RAW on auto WB, and the camera pretty much got it right. I guess I should say that the combination of Lightroom 3.3 and the camera pretty much got it right. It is a tricky shot to WB since there is natural light coming from his right and a mixture of incandescent and fluorescent from the left and front. His neck still looks a bit green to me, but I think it was the best WB I could get with that lighting.
Are you using Lightroom 3.3? One of the members on another forum pointed out that Aperture is turning GH2 files green at the moment, so if you're an Aperture user, a fix should be forthcoming.
