which color should use for photoshop cs4 ?

kryster · March 24, 2010

Camera shooting with adobe RGB 1998 ( raw )

lightroom 2 use Prophoto RGB ( when edit )

monitor use Spyder 3 calibrate .

Ezprints use ezprints 2008.1 icc for printing .

so...... in photoshop cs4 , color setting .. which one I should use ?

I use ProPhoto for the basic color space in CS4, just like in Lightroom. But you must be aware that when you save a file from CS4 you will want to decide what color space you want to save it in - sRGB, aRGB, ProPhoto tiff, etc.

You will want Photoshop to ask you what color space you want files in if they are not tagged as ProPhoto also.

This setting is only for camera JPEG files, the raw files are usually in a latent "raw colour space" (monotone) which needs to be developed into colour (Bayer Demosaicing).

lightroom 2 use Prophoto RGB ( when edit )

If you mean the internal editing space, it is not strictly ProPhoto as the gamma is linear. This internal colour editing space is abstract/transparent to the user - what matters is the colour space that you are exporting/rendering to from Lightroom. If you have ProPhoto set as your rendering space - then the files coming out of Lightroom should be in ProPhoto and should have a ProPhoto ICC profile tagged to them, these rendered/exported files are in the true ProPhoto 1.8 gamma working/editing space.

monitor use Spyder 3 calibrate .

The OS uses the monitor profile, one does not set the monitor profile as the RGB working space. Photoshop will "talk" to the OS so there is no need to manually set the monitor profile as working space.

Ezprints use ezprints 2008.1 icc for printing .

Convert a copy of your master file to this output space if it is an outside service.

The working space in Photoshop colour settings may make little difference to many peoples workflow, as Photoshop will work with multiple images in multiple colour spaces if they have an ICC profile tagged to them. The working RGB is more for untagged, non colour managed images.

thanks so much for the detail explanation ,

so, raw to lightroom is doesn't matter what color setting ?

I still figuring out why my pic become this ..

it is a raw file , export with lightrom , the jpeg and preview in windows look weird ..

Lightroom "knows" what colour your camera "should" produce, so it "correctly" translates the native latent camera colour into the internal Lightroom editing colour space, which the user does not see/access.

The colour that the user selects in Lightroom is the "export" or "rendering" colour space. It sounds as if you have selected ProPhoto RGB (which is not similar to a monitor space, which is why ProPhoto RGB looks so poor in a non colour managed application).

The MS program is not colour managed, it probably uses monitor RGB.

Rendering/exporting or converting your raw images into monitor RGB is not a good move. If you wish to view your images in non colour managed apps, dupe them and convert them to sRGB (or render/export a second file in sRGB clearly marked with an sRGB filename).

ummmm, but what should I do with EZprints for printing ?

if I use sRGB for display ,

and they will print different color if I use sRGB jpeg ..
( sRGB jpeg show same with lightroom )

but with ezprints 2008.1 icc, it look different with what in lightroom ..

so headache ..

One *does not* ASSIGN the Ezprint profile to the ProPhoto RGB (or sRGB) image.

One *does* CONVERT TO PROFILE to Ezprint.icc from ProPhoto RGB (or sRGB), probably using Relative Colorimetric intent, or Perceptual intent.

Interesting however that the color appearance with this profile assigned doesn’t appear to do much of anything. I wonder if its an sRGB profile with a different name or something. Assigning a profile should make it look pretty wacked out.

There should be a warning in CS3 when using the assign profile command (which can be turned off) - which is there to try to avoid the very common confusion between the role of the assign and convert commands.
