When converting Raw to JPEG for web, does anyone check the "ICC Profile" box and save? I just realized the Jpeg has a less saturated look from the original. And for some reasons, I clicked on the ICC box and saved and realized the original colors perserved. Can anyone explain what it is and when should I use ICC? anything wrong using it?
I just start to shoot RAW today.. sorry if it's been asked before.. :oops:


edit - I uploaded two files with and without ICC to my site.. and they look the same. Did i do something wrong?

Make sure your color profile is sRgb, and sure, embed the ICC profile, it can't hurt and it might help. Most programs assume sRgb anyway.

All web browser don't use colour management so the default is not to save the ICC to save file space. If you view this in a colour managed programme it will probably assume AdobeRGB rather than sRGB causing it to look desaturated.

second Tim: Safari on the Mac is the only color space aware browser. All others ignore ICC profiles, and just display the file. If the file is in Adobe RGB it will look flat then. Use sRGB, and embed the profile for the benefit of mac users ;)

A bit off topic, but actually:

1. an sRGB image viewed in Adobe RGB space looks more vivid
2. an Adobe RGB image viewed in sRGB space looks less vivid

Sorry to nit . . . it is true and somewhat counterintuitive.

#2 is the common mistake made when photogs edit images in PS and post them on the web without converting first to sRGB.

#1 leads to a simple technique for intensifying colors on sRGB images. Just assign the "wrong" profile - Adobe RGB - while viewing in a color managed environment.

Agreed, I thought #2 fitted the experienced symptoms of the OP re the reference to viewing AdobeRGB in an unmanaged browser?

Thanks all. But do you convert sRGB in the color settings in CS2?
When I click edit->color settings, my working spaces(RGB) is sRGB IEC61966-2.1 and the Color Management Policies are all set to Preserve Embedded Profile.
When I click edit->convert to profile, my Destination Space Profile is Working CMYK - U.S. Web coated (SWOP) v2.

Do i have to change anything to make the color right in the web? and what else do I have to change? :confused:
Btw, my camera setting is sRGB, not Adobe RGB.

You don't have to do any conversions. Just print/display your images.

re: edit->convert to profile - working cmyk....
That just represents the default or most recent profile conversion you performed. There is a drop down list for other possible conversions. However, you don't need to make any conversions.

IF
your working color space had been Adobe RGB, then you would select sRGB from the drop down list. After conversion, the image wouldn't look any different within PS (since it is color managed and thus ICC profile aware) but would look different in a Windows web browser compared to a non-coverted image.
