Copy and paste White balance settings in Develop panel not working properly. Temp and tint values are different and not match the copied value!

[DdeGannes]

The source image that you are copying the WB from is it showing "as shot" as its white balance?

[Pedercarlsson]

My mistake. yes it was set to "as shot".

Of cause it should be set to "Custom" when you want to copy/paste temp and tint.

Thanks DdeGannes for fast reply 😉
