Colour matching background studio shoot

[sebastiensiegenthaler]

Hi Everyone, 

I could use some advice. I recently did a studio photoshoot where I photographed employees in front of a colour background. 
Somehow my white balance was set to auto which changed the colours of the background. The background colours all have to match. What's the easiest way to do this as I have many pictures to edit. 

Hope you can help me out, thanks in advance!

Assuming that the background is not grey, you could try clicking on a neutral grey area in the image  (if there is one) with the white balance selector (press W). Some fine tuning may be required.

This will of course change the color balance of the whole image, not just the background.

If you want to change the color of the background only, you'd have to create a mask on every image (select background), and then edit the images one by one. Reference view will probably be handy for this.

If you shot in RAW, white balance setting is irrelevant. Just batch change all the images to the same color temperature and tint.
