No, I haven't played with white balance yet. I've been using the color balance layer though. It turns out that CS5 can't open the EM-1 raw files (but it would open the EM-5 raws when I had it

) so I'm just playing with the JPG files for now.
I've downloaded the DNGConverter from Adobe. Haven't installed or tried it yet. It'll be a pain if it doesn't allow similar controls to camera raw though.
