P: Camera Raw: Magenta color in recovery light for 70d

Thanks Jeff, much appreciated.

We're investigating this to see what can be done.

I did some investigation of this issue as posted here:

https://forums.adobe.com/message/7110...

What I discovered is that both of the 70D CR2 raw files downloaded with this issue have one or two G /G2 pixels at a much higher level than ALL of the other R G B G2 pixels. I checked Canon 300D, 600D, and 5D MKII images with significant clipping and the R G B G2 levels were within 1 least-significant digit count. (14736, 14737), which amounts to a difference of only 0.007%. Both of the Canon 70D CR2 files had one or two G/G2 pixels at levels >7.0% higher. LR appears to be using these "single pixels" to set the G/G2 highlight clipping level used by the Highlights recovery control.

Even RawDigger gets confused when setting the highlight clipping levels for the G/G2 channels for these two 70D CR2 files. The fix will probably require a new Process Version (PV2015?) or a firmware update from Canon to limit the G/G2 levels so they match the R and B channels maximum level.

Yes, I realized that the problem is not the camara, its the lightroom's problem with that specific camera. And it looks like the problem has to be popular/common for them to do something about it. So who knows when they wil fix it.

Oh, it's not a camera problem, Serg - it's definitely an issue with the Lightroom profile - but it shouldn't be hard for adobe to fix.

I have the same problem and it drives me crazy. I get pink highlights when i try to recover overexposed(clipped) highlights. And even when they are not clipped, if I bring down exposure and highlight far enought, the highlight get pink hue. The camera that I have is canon 70D too. Previously I had nikon D7100 and hever had this problem even if the photo was really overexposed. So I figured that if I do exposure bracketing shots and then convert to HDR it would fix my problem. So I selected my 3 shots in lightroom(5.2), and then right click > edit in > merge to HDR Pro in photoshop. Then I selected 32bit mode and saved it. It saves TIF image into my Lightroom catalog but the result is awful, hightlight are pink and basicly no matter what I do, the HDR image doesn't look any better. It means there is also a problem with HDR Pro plug in in photoshopCS6. Below is HDR photo, regular photos donr look any different

Shoot of my room, look at the magenta outside the window !!

This with recovery light at -100

Just to support this problem report: I've tested the Canon 70D files provided by Max in a number of other converters (Photo Ninja, Capture One 7 Pro, ACDSee): the heavy "magenta highlights" problem ONLY appears in Lightroom, and it's a pretty bad example of the problem.

Just by way of summarising the content of the link referred to above:

Primarily in clipped highlight areas - 255/255/255 - Lr's usually excellent highlight recovery is generating SIGNIFICANT false colour, even at relatively low settings.

This happens with the Adobe Standard profile and with the "Canon Style" profiles.

It's an Lr-specific problem (it's not the Raw file); and it's NOT just a minor occurrence of the issue - some files will be unusable in Lr pending a fix.

See attached example - ONLY adjustments are white balance (which makes no difference to the problem) and highlight recovery.
