Vista Color Management

Vista Color Management

2007-04-18 by rw3st

Has anyone had any experience using Vista's Color Management? I've got 
PrintFix Pro & Spyder2Pro, all drivers & software are working (fairly) 
successfully, but I am unsure as to what I should be doing with Vista's 
color management's settings, both before and after calibrating. 

Any suggestions (or better still step-by-step instructions) will be 
greatly appreciated.

There was a lot of PR about the new color management engine in Vista for the year before its release, but most of it does not actually apply to the released product. Vista defaults to the same ICM2 calls and settings as XP (and 2000, and Win98...), and there is not really any way for users to access anything more, so its basicly a matter of what minor fixes or bugs were introduced.

As far as I can tell to date, the Windows bug where an application asks Windows to set a profile as the default monitor profile for a given monitor, and Windows for some reason fails to do so, and also fails to return any kind of warning that it didn't do so, is at least reduced. But that may just be because Vista does not support the videocards with which this was occuring.

On the other hand there is a new issue where XP assumed sRGB; if there is no monitor profile set at all, then sRGB is assumed. This was problematic as sRGB isn't really a monitor profile and has no VideoCard corrections in it, but at least its a profile. Under Vista, its possible to query the OS about the profile for a given monitor, and get the answer that the default profile is... none. Not good.

But both of these issues are about situations where there is something wrong, and Windows doesn't handle it very gracefully; if nothing gets messed up, you won't run into either. The new Color Control Panel looks pretty, but it basicly sets up the same stuff, with a bit more visibility and a bit more flexibility. Still no real way to use Windows Color System profiles and stuff, just the old ICM2 calls for ICC profiles, but at least that still works; I was more worried about what Vista would break than what it would add.

Most color mangement issues under Vista have to do with what applications are Vista compatable at this time, or what printers and color measurement devices have Vista capable drivers; the same issues that are paramount in general Vista use.

So download the lastest "Works with Windows Vista" versions of both Spyder2PRO and PrintFIX PRO from the colorvision.com website, and just run them as you did under XP... should be fine.

This is quite interesting. From your description it sounds like not 
much has changed in the ICM. I was under impression that apart from 
bug fixes the ICM inside Vista's WCS now also supports things like 
ICC V4 (honestly, I do not know if it matters much for monitor 
calibration, but anyway). I wonder if the updated ICM offer any real 
benefits in terms of monitor calibration and the display accuracy? 

A little bacground - I am among those people on WIndows XP that have 
problems with the way Lightroom displays the image in the Develop 
screen as opposed to the the way the image looks in the exported file 
in another color managed app (the difference with my setup is mostly 
in deep blacks under certain develop setting - this all with Spyder 
calibrated monitor etc.) - Adobe seems to be pointing the finger at 
the Windows ICM that LR uses to generate its on-screen previews.  
Initially I thought that Vista might cure this due to its upgraded 
ICM, but I have seen reports that the same problems occur in LR also 
under Vista. This and what you are saying seems to suggest that Vista 
does not offer any improvement (at least as far as LR is concerned).

Sorry - what I actually meant was what settings should I be setting in 
Vista, both before and after calibrating. 

I want to calibrate my monitor - so before calibrating do I go into 
Vista Color Management and set it to 'Use my settings' and then remove 
any existing profiles? 

After calibrating my monitor I noticed that Colorvision software starts 
up automatically with Vista and loads the profile. This is what I do 
not understand - is Vista Color Management also loading the new profile 
as well?

What I am specifically trying to avoid is Vista using a profile as well 
as Colorvision using a profile (if that is even possible).

This is a cooperative venture. Windows (including Vista) is in charge of the housekeeping chore of assigning profiles to monitors and remembering them. The monitor calibration software automatically, and invisibly, makes this request of Windows, and the profile is assigned, you don't need to do anything about this unless Windows fails to set this successfully... see previous post about details of that. The other half of your monitor color management is video card corrections (called VLUTs) that need to get loaded to the videocard. Windows (Vista included) does not automatically do that, so our startup utility does. So there is no danger of "the profile being loaded twice". There is no danger of the video corrections being loaded twice either. Since they are the same VLUTs, even if you did load them again manually, it would just overwrite correct data with the same data. Its when another application loads the wrong LUTs that you get in trouble. So avoid any software that does that. Use only one monitor calibration tool at a time.
