White is not white in Photoshop CS3

"Ataruchan" wrote in message

Hi, sorry but I am a primer and I don’t get this.
I’ve a Lenovo tablet x61 and Photoshop CS3 on it. The Color Manager in the Lenovo control panel has a Lenovo ThinkPad LCD monitor profile as default.
When I open any image in PS it says that the document has an embedded color profile that does not match the current RGB working space. If I choose to use the embedded profile the white will be turne a little bit to red but only in PS. Discarding the embedded profile will turn the white…white…but it won’t be this way outside PS. What is it wrong? Do I have to format and reload everything? Thank you,
Ataru

What is wrong is that you don’t really understand color management. A good place to start would be Ian Lyon’s website (www.digital_darkroom.com) (If I remember it correctly that is).

In this particular case, you should convert the document to your working profile. Then, when you are done,
you can decide what the output profile should be.

When you are ready to print, you decide whether PS or the printer driver will be responsible for color management. I prefer PS if for no other reason than what is every program’s business is no program’s business. In such a case, turn off color management in the printer driver. If you don’t take such a step, you will be applying the profile twice, and you willl not like the result.
A good book is "Real World Color Management" by Bruce Fraser. Jim

Thank you again Jim. Yes, the website you suggested cleared me a lot about profiles and color management.
For the moment I don’t have print jobs but I’ll follow your suggestions at the right time.
Oh, and I got that book from US…it will be here in Europe in a couple of weeks…I couldn’t imagine you need an entire book for that! Great and thank you again.

I’ve got a Thinkpad X-Series as well (not tablet version) and I absolutely love it for everyday use, but it is ridiculous to use such a machine with Photoshop, IMO.

ss.

I’m just wondering here, I am using Photoshop and I am _not_ printing. I just want white to be (255,255,255), and every color to appear as its proper RGB appearance, like it would in any other program. Is there any way to just throw all of this stuff out? If I open it in Firefox, Quicktime, etc. (anything except for Photoshop and the default Windows image viewer), it appears correctly, but Photoshop seems to want to do my job for me, and its doing it wrong.

Photoshop is a colour managed application, the programs you mention are not. It never ceases to amaze me how people can lay out all that money for this program yet still refuse or are unable to set it up to work correctly. You need to calibrate your monitor and printer (at least your monitor).

Read http://www.computer-darkroom.com/ps8_colour/ps8_1.htm for starters.

In the mean time try the following
Open an image that contains something that should be "white". Click on the foreground colour swatch to open the colour palette. Click on the part of your image that should be white and read off the RGB values in the colour palette.
They should read something between (all channels) 240 and 255. (My "white" is 243,243,243 BTW, but that’s another story) There should not be any great deviations in the values between the channels only 1 or 2 points at most.
Any more denotes a colour cast in that channel.
Then with your image still open, open the Levels dialogue (ctrl +L) and with the right hand eyedropper click on the part of the image that should be white and see what happens.
