I seldom do anything but custom white balance but there are times when I just have to start shooting and can not do a Custom WB for a few minutes.

I am not big on AWB, it may get it right but then changes while recording. (or at lest did with the XHA1.
I would probably choose a Preset, but can not see how to change it, seemed it was on the top with the EX1, I am now using the EX1-r.

I can not find my manual right now, gonna see if I can find it online.

You can change it in the Picture Profiles.

Thanks, was it the same with the Ex1 too, seems that it was on the top, but that could have been on the XH-A1.
