How to Remove a Color Cast

[Major Major]

Here's one way:

1. Create a copy of the layer (ctrl or cmd+J)
2. Filter, Blur, Average
3. Create a levels adjustment layer, then
4. Select the gray eyedropper, click on the Blur, Average layer
5. Delete/turn off the visibility of the layer copy you created in step 1

Yesterday, I was walking through a rail yard in off-and-on drizzling rain, taking pictures; due to the heavily overcast black cloudy conditions, I set my white balance on "cloudy".

When I stepped into the brightly lit depot, I forgot to change the white balance; and, thus, all my inside pictures are entirely orange.

I followed the provided instructions and was amazed to watch the orange disappear.

I would never have stumbled upon this method in a thousand years; in fact, I would not have imagined it would work, but it does.

Thanks for the instructions.
