Confusing (red) colour shift/cast behavior ADBRGB ->sRGB
C1 v8 (8.3.2.12)
PS CC2014
Windows 10
Samsung 4k AdobeRGB monitor w/x-rite colormunki
Shooting to Adobe RGB in camera
After shooting tethered (if that matters) and adjusting my selects, the colour shown in C1 is perfect but when exported to 16bit PSD and opened in CC2014 shows a red colour cast.
I am using a calibrated monitor, the monitor is using the calibrated ICC profile. Photoshop preview colours is turned off. PSCC2014 colour settings are
Working Spaces:
RGB -> Adobe RGB
CMYK -> U.S. Web Coated
Gray -> Gray Gamma 2.2
Spot -> Dot Gain 20%
Color Management Policies:
RGB -> Preserve Embedded
CMYK -> OFF
Gray -> OFF
Conversion Options:
Engine -> Adobe (ACE)
Intent -> Relative Colorimetric
Use Black Point Compensation = Y
Use Dither (8bit/channel images) = Y
Compensate for scene-referred Profiles = Y
Advanced Controls:
Desaturate Monitor Colors By: "20%" = N
Blend RGB Colors Using Gamma: "1.00" = N
Blend Text Colors Using Gamma: "1.45" = Y
Attached are links to two screen caps.
1. Left = C1 v8, Right=PSCC2014
2. Left PSCC2014 -> Save To Web dialog converting to sRGB
Save To Web shows the original different than it is shown in the document window. And the converted sRGB looks more like the view in the PS document window.
I am at a total loss as to why this is happening. At this point I am resorting to applying a selective colour to remove the red cast to every file exported from C1.

Can anyone shed some light as to what might possibly be going on here?
Thanks,
Adrian

The confusion continues....
I've been researching this for the past hour and I may have an explanation, but not a solution.
PSCC2014 is using the monitor RGB set to sRGB. But in my monitors colour management settings, I selected my calibrated ICC profile.
I cannot find anywhere else in Windows where I would tell the system to use the calibrated profile and not sRGB. Nor is there anything I can find in PSCC where I can even override the sRGB setting and tell it to use the calibrated ICC.
I've made changes, restarted, made changes, restarted and still no difference in what PSCC is telling me Monitor RGB is set to.

I re-profiled my monitor and low and behold, PSCC now shows the new ICC profile as the Monitor Profile.
Files pulled in are now looking as they do in C1.
Wracked my brain but figured it out. Put it down to a corrupt ICC file.0 -
Looks like you messes up your color icc porfile.
Keep in mind that SRGB is smaller then ADBRGB so mapping of colours occurs, and you photoshop setting is relative colorimetric. That`s why compensation messed it up0 -
As I've been researching things more and more, it appears there are a couple of things here in play that don't make sense.
First, as in a recent post. The default ICC profile in C1 is Phaseone's own Nikon default. I feel that this is actually wrong as in camera, I have it set to AdobeRGB. THe problem with C1 is I cannot find a way of defaulting AdobeRGB in this field. I have to change it manually everytime.
Then there's the mystery of PS CC. When using the save to web tool, the original side shows a desaturated image and the output shows an image that is much warmer (red saturated) which is closer to how it looks when editing the image.
I understand that sRGB is a smaller space, that's what puzzles me.When the conversion happens, red saturation goes through the roof rather than be desaturated which is what you would expect when shrinking the gamut.0 -

Are you working with RAW (NEF) files or the Nikon jpgs?0
