Green Tint in Shadows?

I am having a real issue with my 1DX - when I underexpose (which is a lot, I tend to shoot on the dark side) I am getting a greenish tinge that shows up badly when I bring the image up in ACR. Here is a link to a dropbox folder, the image is in it (MBP_9064), there is another image in there I posted about earlier, with weird brown patches on the bride's face, feel free to comment on that too if you like! Here's the link:https://www.dropbox.co​m …155m6pw/MBP_220​5.CR2?dl=0

An image is a capture of reflected light.

The light reflects off of the grass and the only illumination on them is reflection from the green grass. 90% of the scene is green.
Without a reflector, flash or neutral colored natural reflector, any time you shoot in this much "green" this is what you will get. To me is normal for the are that you are shooting in.

Also since i have to bring the exposure up by 2 stops, this may just be amplifying the problem. You need to find out what you are doing to get an image this far under exposed and you should have less problems over all.

I assume that none of the pictures that you shoot away from grass have a green tint? If this is the case, then refer to the reflector suggestion above.

You can always darken an image without doing as much harm as you do shooting under and boosting.

The link is to MBP_2205 so I'm not sure we're looking at the same thing, but the shot I see is very underexposed too. It was shot Av, Pattern Exposure, with -1/3 EV exposure compensation. Given the white dress and bright sky peeking through, I'd have been well into positive territory on the EV if I didn't spot meter in manual on the dress.

Makes perfect sense. I'll have to think on what solution I'll use to try to remedy this since in wedding situations I usually don't have time to bring out the reflectors & I hate to use flash unless i have time to set up OCF. Thanks for the simple explanation, that works best with me

i dont know, I've always found personally that in wedding situations, when I was shooting brighter & having more over exposed images, Ihad a lot of problems with bringing back the dress details. I just need to find a happy medium obviously

Of course you dont wamt to blow out the whites, but you cant be overly cautious and underexpose everything to make it eadier to control highlights.
