Hello folks.

This shot was taken RAW and I didn't do anything to it except resize and convert to jpg for putting in this post. No PP whatsoever. It was taken where we were more or less surrounded by trees so I was sort of prepared for everything to have a green cast. The problem is that I can't get it out.

Actually, I see it as blue in the hair on the top of the head and the white blouse. I can put so much yellow in it that she looks jaundiced and you can still see the blue in the hair. On the chance that it really was green, I tried magenta and you can still see the color in the hair no matter what. (Her hair is actually silver/gray with absolutely no color to it.)

Fixing the density first didn't do any good either; the blue's still there.

This reminds me of trying to print a negative that's been screwed up in the development process so that it's impossible to get the colors right. But it seems that something like a color cast from the surroundings would be easy to fix.

What am I doing wrong?
Thanks a lot.

It's not blue, it's green, at least on the uncalibrated monitor i'm on right now.

You need to adjust your white balance. If you're using RAW do it in your raw converter with the white balance tool. If you you shot jpeg then the levels tool is a quick and dirty way to do it, use the white or grey droppers then click on the white top or the more pure white of the undershirt.

I'm really only familiar with Lightroom so best I can tell you is open the develop module and go into the HSL area. I would try the saturation and start dialing down the blue. Or click the little selector box on the top right, then move your cursor over the offending areas. You should see the color slider highlight over the colors. Move around til you find the blue slider light up. Then click and drag the saturation down. Also you can try the luminance as well.

Like Tim said - easiest way is either in DPP or ACR use the white balance tool and click on her shirt.

Here is a quick edit in PS on your JPEG, using Lab curves to adjust the greenish tint toward magenta. A similar curve was made in b to balance this boost to the apparent saturation. You could go further if you wanted to really fully neutralize the hair, painting in a localized correction on right side hair and neck that is likely picking up heavier color bleed from green foliage.

I also made a little contrast boost in the L.

Here's a quick edit using LAB WP and BP to balance it out in both channels.
I also added some contrast and vibrance, just to get some separation.

Well, this is really amazing! Changing the white balance fixed it right up. I tried with both RAW and jpg versions; I like the result I got with the RAW better. (I had no idea that was how the white balance adjustment in DPP worked; I find their documentation leaves a LOT to be desired. So thanks for that plain simple instruction, Dennis.)
So thanks, everybody.
Now can someone tell me why using the RGB adjustment (either in DPP or in Gimp) didn't get that green/blue out?

White balance/color temp just works better. You're defining white, rather than trying to manually change colors. I don't know the fundamental reason though, even after reading a book on color.

Any change is best accomplished in RAW. WB is a one step fix.

WB adjustment to the RAW data works better basically because it is done while the data is still linear. In a rendered image a gamma 2.2 tone curve has been applied which skewers the tonal relationships and makes the math much harder.

It's always best to adjust the WB early on in your raw editor, but occasionally I use a color cast correcting filter in NIK software.
