now we make a curve adjustment layer:


take the neutral color picker (the middle one) and click anywhere in the brownish area
(marked with the X) - voila, your brown shows as neutral gray:

here how this simple move applies to the RGB channels without me (or you) touching a single curve:

now you can simply deactivate (or toss) the middle layer to see the final result - pretty cool, huh:

The easy way out: If you go into the curves "options" dialog you'll find a "Snap Midtones" option which works almost (but only almost, depending on the image) as good:

This doesn't work right for me. Did everything as said and does what you said but I get a massive green cast to final image. There is a large red flag in the image though - so I gather this only works when the image is pretty much neutral on average to start with? Or maybe I'm missing something?
BTW Found some cool tips on your site. Thanks!

Thank you so much for this Markus. Reading through this before trying it, I didn't think it was going to work; it just seemed too simple, espescially condsidering the amount of grief this issue has caused me. However, it works fantastically,
BTW, I've been a big fan of your work for a while now.
Thanks again.
