RE: filmscanners: Does CMM work on Win2000?

Hi Maris 
 Thanks for responding.

>>Windows interprets your embedded profile as an sRGB image and adjusts the
>>colors accordingly.
  But my image is tagged as ProPhotoRGB. I think, before interpreting as
sRGB,
  windows is supposed to do some gamut mapping from ProPhotoRGB to sRGB. 
  

Thanks
Ramesh

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
| Ramesh
