Why doesn't white balance sync across multiple images?

[Mark Sirota]

One subtle point about syncing white balance: If your source image (the "most selected") is set to As Shot, then the others will also become As Shot.

If you want to sync the actual temp and tint values, the source image needs to be something other than As Shot. Changing it to Custom before syncing is the usual recommendation, if you're happy with the temp and tint values.
