Title: Weird Colors with profiles
Post by: RonNYC on November 03, 2008, 07:27:49 pm

These are tiff images imported into CS2, originally shot as raw in my Canon. While the image comes in as color, I use the channel mixer to convert it to B&W appearing (but it is still 16/RGB). On screen the image looks great but when I assign a profile, like either Epson's (I have a 2200) Advanced Matte or Hahnemuele's Museum Textured profile, the image becomes blue. This is true when the image is a straight color image (i.e., not gone through the channel mixer). This is true for all the Epson SP2200xxxx profiles as well as Hahnemuele's profile. Blue or green. What am I doing wrong? Any help is greatly appreciated!!!

Answered on the Adobe forums...you don't assign, you convert.

I did try that, but everything now turned reddish (as I mentioned on the Adobe forum). I know it's me, just what?

Mr Gans,

I think Jeff misunderstood your question.

If I understand you correctly, you are trying to assign a printing profile as your working space. This is a big NO NO. The profiles from Epson and Hahnameuhle are for printing and soft proofing only. They are applied in the Print with Preview dialogue when you are sending the print to the printer.

ColormatchRGB is your working space within PS. Leave that alone, DO NOT assign nor convert this to any printer profile. This is where you are getting the green cast.  I followed your workflow you posted here and on the PS forum  to duplicate what you are seeing.

I think you need to learn more about color management and workflow. I think this is a good start.

Here is a good tutorial by Ian Lyons on printing. The screenshots are for a Mac but the steps and basic flow is the same for Windows.
