FIX WHITE BALANCE IN PHOTOSHOP

Photoshop is an interesting beast. There's more than one way to do anything. That's the beauty of the software. Of course, which technique you use is based on the situation and personal preference. The same goes for white balance. You could use a grey card, adjust in camera, or just fix it in post. It's up to you and what functions best for your workflow.

Personally, when I shoot, I'm mostly shooting based on the relative area of my light source. Meaning, if it's tungsten, I'm shooting based on that. It typically gets me in the right area and I can adjust in post because I'm shooting RAW. Some times I do a custom white balance with an ExpoDisc, but I've been doing that much less. My white balance now is usually being corrected in post.

Here's a neat trick to add to your bag of tricks for correcting white balance in Photoshop. Create a new layer, fill with 50% grey, and set the blend mode to difference. Next, create a threshold adjustment layer and drag your right slider nearly all the way to the left. Basically until you there are just a few areas in black. These are your midtones and closest to 50% grey. Use your handy color selector tool and select a point in one of those areas. Now, hide the grey and threshold layers and create a curves adjustment layer. Grab the grey point sample too, which is the one in the middle, and select the very same point you created before, the one in the midtones, and feast your eyes on corrected white balance beautifulness.

This trick seems a little long, but hey, it works. And it's another tool to add to your bag of tricks. Check out the video above for a very nice walk through.
