Photoshop elements 10 raw converter white balance has only As Shot, Auto & Custom in the pull down menu. What happenen to the other options, i.e. Daylight, Cloudy etc.?
I think that you may be opening a JPG in the editor using the Open As option. In this case you get the restricted set that you mentioned as the full raw data is not available.
If you open a raw image, then the full range should be available.
