Was this before or after the problem appeared?

No. For that I'd make a new blank document, and File>Place your master PSD into it.

No, it's the top group you need to mask.

It doesn't matter. Just do exactly what I said.

I'm so sorry Ashleigh, I've got nothing. It's very severe.

What happens if you remove the action, then re-load it from where it's saved on your hard drive? Does simple re-loading fix the problem?

I'd say it's the Gradient Map layer.

Can you define "all of a sudden"? Do you remember which day this started happening?

Make sure you follow my calibration directions here.

Which Spyder do you have? Oh heck yes, that might be relevant. Probably better recalibrate right away, eh?

I promise, your file is perfect. Smooth as silk. Can you try something for me quickly? Go to Edit>Assign Profile, and assign your monitor profile to the image. Does that make it look worse, better, or no change?

Can you send me a full-resolution file with the problem?

Do you see it here in this thread as well? On your computer, I mean? Or is it only visible in Photoshop?

Yes, it's not visible to me either. So it must be a problem with your screen or graphics card.

Well, I would ask them to send you one of their raw files right away, to check.

Perfect.

As long as you're sure they're not too wide ... ?

Oh yes, that's excellent.

There must be a black-and-white layer in the group that's desaturating everything underneath it. Just add a mask to the group and make sure it's only being applied to its half of the file.

Well, if you really did use a vector mask, that's your problem. Never use vector masks for this. May I see a screenshot of your whole screen?

You'll need to apply some cooling filter to the angry warm parts of the face at the top left, won't you?

No, sorry. I'm not aware Bridge has ever had that feature. It's the domain of the camera manufacturer's own software - eg NX for Nikon, DPP for Canon, etc.

Blowouts.

Excellent. So now, as long as you have soft-proofing turned on while editing, your histogram will be accurate and you'll be able to edit without the clipping in his face.

I can't think of a better way. You've done amazingly well.
