Batch processing changes in WB

[Harmless`]

Can anyone tell me if its possible to batch process RAW files to change their white balance.
I've just taken about 300 shots with the wrong WB and the other 300 look better on Auto than the one I selected.

I'm using the Canon software and have Lightroom, but have never used it yet.

Hope there is a way or this will be a very tedious few days!

I only use Lr or ACR.

In Lightroom, import the images, select the first image to correct the white balance - very simple.

Now with that image selected press Control A to select all images and then in the develop module click the sync button and you can select the parts you want to sync. The first selection being white balance.

Takes 1 minute once the images are imported

Thanks. That'll save a lot of time and hassle.
