I have an NEC Spectraview PA271W which is wide colour gamut and am using it with CS6. My CS6 colour space is sRGB as I work for web and print and the publishers are happy with sRGB images.
All was sunshine and light when I had an sRGB equivalent NEC 2490 - never had any colour problems. But with the 271 when I open images outside of Photoshop (eg in Fastone Viewer) or on the web, they are oversaturated. But when I make a screen capture of the (correct looking) image open in CS6, and look at the saved screengrab in Windows explorer it looks fine. I am baffled by this.
The image is sRGB, sRGB is my working colour space in Photoshop, I am converting to sRGB when I save for the web. I am using my display in sRGB emulation factory set mode - why are saved Photoshop images looking oversaturated in the world outside Photoshop, but saved screen grabs of the same images open in Photoshop look ok there (the outside world)?
I have calibrated the display but this has made no difference and I find the detailed calibration instructions largely unintelligble. The software (me being in Europe) is Spectraview Profiler 5 and the calibration puck is an x-rite i1 Pro.
If anyone could tell me why I am experiencing the colour discontinuity I have described that would be wonderful..
You're seeing what's expected.
Unfortunately, with the state of affairs in the computer world, it's necessary for every individual application to do color management of images it displays.
The root of the inconsistency you're seeing is that not every application (including browsers) does proper color-management.
Internet Explorer, for example, reads document profiles and converts every image to sRGB IEC61966-2.1, no matter what your monitor profile. Some applications don't even read document profiles, and sometimes some applications that DO read both the document and monitor profile just get it wrong!
A lot of things become simplified and more consistent when the monitor can do a good rendition of sRGB and you use the sRGB profile, which sounds like what you had before.
If consistency across all your applications is important to you, your task will boil down to seeking alternate/updated applications that do proper color-management.
I still do not understand why the colour phenomenon I described took place. Everything is set up for sRGB so nothing should look garish in unmanaged colour environments through mu display. But as I described above, in one case you see it and in another, you don't. I do not want to use clolour managed browser because still, most people don't including people who will be looking at my pictures on the web. They also mostly will not have wide colour gamut machines. So - sRGB top to bottom seems to be the way to go. Except - in the instance I described above - it doesn't work. My monitor does a very good rendition of sRGB.
Still at sea.
That, Gernot, is a very good question. I think the answer is yes - here are a couple of relevant windows:
But - despite these settings - looking at my screen now, I can clearly see that the colours are too hot. If you have any really simple advice on calibration and profiles I would be glad to hear it. Thanks.
Calibration seems always to mess sRGB up - maybe I should just leave in sRGB factory mode with no profile loading.
building a custom profile from the sRGB factory mode (hardware preset) doesn't work? not saying I recommend that, tho
FWIW, i took back my wide-gamut monitor about four hours after i opened the box (the time it took me to figure out what was going on, and that no amount of calibration/profiling would fix the problem)
the problem is Windows and Mac (10.7) operating systems default to sRGB (for sRGB display environments, ie standard-gamut monitors) — wide-gamut monitors are AdobeRGB devices
if you want to test this theory, just open a normal tagged sRGB .jpg in Photoshop (use the embedded profile), then View> Proof Setup: Monitor RGB
if your monitor is closer to sRGB, i would expect to see a slight boost here in saturation and black point (this is what you want, not an exact match)
if you are using a wide-gamut display, the reds go on fire here (real headache if you work on the web)...
WIDE GAMUT MONITOR TEST & more info
I think I have the answer. Pilot error. I was viewing images in CS6 with "Proof Setup" set to " Internet Standard RGB (sRGB)" - this muted the colour in CS6 but not everywhere else. When I set the Proof Setup to "Monitor RGB" I saw the image with more colour saturation. When I corrected the over-saturation in CS6 and saved the image, it looked correct on my wide gamut display outside of CS6.
I hope this solves the problem. Thanks for all the advice.
>> I have the answer. Pilot error...When I corrected the over-saturation in CS6 and saved the image, it looked correct on my wide gamut display outside of CS6.
i'm going to assume you mean user error, and that you made the sRGB image look bad (boosted saturation a bit) in Photoshop to compensate for un-managed environments displaying sRGB on WIDE GAMUT 'AdobeRGB' DISPLAYS
i don't like to say this, but (excuse me for that but) you still don't understand what you are doing yet — just look at your "corrected" image on a standard-gamut monitor in managed or unmanaged apps (if you don't have a standard monitor available, it's going to look a lot like the over-saturated "corrected" image Photoshop is showing you)
you would do everyone who is trying to learn from the advice here a service if you unmarked your conclusion as "correct" so as not to further confuse anyone
you basically have two choices using a so-called wide gamut monitor for Web work
live with the cartoonish colors, or
set the monitor's hardware sRGB preset
Thanks. I have uncorrected. I thought | was doing what you suggest in your final sentence - use the sRGB factory mode. But this is still showing over saturated colours outside of Photoshop. Do I need to add a calibrated display profile to this and is that automatically loaded by Windows at start up?
>> I thought | was doing what you suggest in your final sentence - use the sRGB factory mode
if your wide gamut monitor is successfully emulating a preset sRGB environment, Photoshop should show only a slight boost in saturation doing my above mentioned sRGB test (View> Proof Setup: Monitor RGB)
if sRGB still goes way over saturated in this test, the monitor is not emulating an sRGB device
again, i don't recommend buying a wide gamut monitor and setting it in sRGB preset to work around the problem, but if you are stuck, the preset is a work around
Yes, gator soup has nailed it down to the options that make sense.
The alternative I suggested in post 1, along with getting your mind around how color-management works, is one approach.
Or, if you're willing to set your new monitor to its sRGB preset and set the color profile to sRGB - which means you won't get the entire gamut your minitor is capable of - then you'll find a whole lot of things will become more consistent.
That's one problem with proper color-management of a wide gamut display... The color-managed apps show the proper color, and those that don't do proper color-management are more often wrong.
Thank you Gator. I'm a little oversaturated, not a lot. So that is encouraging. But I ask again, when I'm running in the sRGB preset do I need to calibrate my display and create a profile? I find this confusing. The software manual is not helpful. Why would I want to create a software profile that messes with an sRGB factory preset?
Thanks, Noel. I bought the display because I will want in the future to take advantage of the wider colour gamut but not for the work I have on for the next few months. One of the reasons I bought this display was because NEC claim (in an FAQ) that it's sRGB factory set mode is more accurate than many sRGB displays. That sounded good enough for me given the provenance of the display. I am happy to work in a smaller colour space for now - that's why I'm going through all this. It is counter-intuitive to me to create a software profile that will just mess with a perfectly adequate factory set colour mode - particularly as none of the contexts in which the images will be seen outside of Photoshop except maybe Firefox and Safari, will be colour managed - and after all, the displays people are using to look at the images in those browsers may well not be wider colour gamut. Even my publisher's displays are sRGB. I've done lots of reading and no doubt I'll do lots more - but the material I've read is not straightforward - to me at least. It is kind of you to pursue this with me.
>> I ask again, when I'm running in the sRGB preset do I need to calibrate my display and create a profile? I find this confusing.
yes, you ALWAYS want to use a hardware profiling package to 'calibrate' (build) a custom profile for your monitor regardless of your factory setting & factory profile (if you want the ability to view your color 'accurately' in Photoshop and color managed apps in general)
Source Space> Monitor RGB: color managed apps, like Photoshop, read an embedded profile and CONVERT (adjust, alter, change, remap) it to the custom monitor profile for a theoretical 'true color' display
the wide-gamut (W-G) display problem you are seeing outside of Photoshop there occurs when your sRGB document is sent straight through to the W-G (AdobeRGB) monitor unchanged (uncompensated for) — you are seeing the difference between sRGB and your monitor profile (your sRGB preset, all sRGB-type monitors, also show this phenomenon, but to a much lessor degree than W-G monitors)
once you figure out what's going on there, it will become ridiculously obvious and predictable...

my point is, color managed apps like Photoshop & Bridge will DISPLAY and print all five tagged .jpg files IDENTICALLY... unmanaged applications/viewers will display and print each file uniquely different
