Re: filmscanners: Does CMM work on Win2000?

I think that's the rub - Windows is not Photoshop.  Windows ignores the
embedded profile - Windows does sRGB so Windows makes it sRGB and ignores
the tag.  Windows does not do gamut mapping to my knowledge.

| I use Windows 98SE so I'm not sure what the settings would be in Win2000,
| but it depends on your Windows "Display" settings.  The default Windows
| color space setting is sRGB, so that would explain why your wallpaper
looks
| the same as Windows wallpaper and in AcdSee as (I assume) AcdSee is using
| the Windows default as it's color space as well.
|
| Windows interprets your embedded profile as an sRGB image and adjusts the
| colors accordingly.
|
| You will have to change your Windows "Display" setting (in Win98SE it's
| "Control Panel-Display-Settings-Advanced-Color Management") if you want to
| modify this.

| | Hi
| |       I know this questioon has been asked in this list for N'number of
| | times, but I am forced to ask again.
| |
| | I scanned the negative in VS, using "ProPhoto" as colour space. Scanned
| | output had profile embedded in it.
| | I edited this image in Adobe PS6.0 and saved on to disk. I set this
image
| as
| | wallpaper of my desktop and also opened this image in AcdSee viewer.
| | Now comes the problem, the image shown in AcdSee & wallpaper does NOT
| match
| | with the image shown in Adobe PS6.0.
| |
| | To be specific the image shown as wall paper  and image shown in AcdSee
| | viewer are slightly less saturated compared to the one shown in Adobe
| PS6.0.
| | Image shown as wall paper  and image shown in AcdSee viewer match well.
| |
| |
| |
| | My PS6.0 setting:
| |  Working space: Adobe1998 (This does not matter though)
| |  Using embedded profile while editing the image.
| |
| |
| | Operating System:
| |  Win2000 Sp2.
| |
| |
| | I do not know why the 3 images are NOT matching. If the operating system
| is
| | following CMM then 3 images should match.
| |
| | I have calibrated my monitor using "AdobeGamma", but I think this should
| not
| | matter if the image is being viewed on same desktop.
| |
| | Please let me  know why all the 3 images are NOT matching.
| |
| |
| | I did another experiment, In Adobe PS6.0, I converted image to sRGB and
| | saved. I set this image as wallpaper of my desktop and opened this image
| in
| | AcdSee viewer. Now all the 3 images matched perfectly.
| |
| | Does this mean, Win2000 assumes that image is in sRGB?
| |
| | Please throw some light on this issue, feel free to ask for more
| information
| | about the scenario.
| |
| |
| |
| | Thanks
