Color Management Questions

dirt lover
I have a 20D and shot the pics with sRGB. I edited the raw files and started the batch processing with embed the camera profile for jpegs. When I open one of them in photoshop, it says that the 20D generic profile is embeded, while the working profile in Photoshop is sRGB (what I want to use). The photo is also sRGB. Does this mean it has two profiles? Also, what is the difference between embeded and the opposite

(which is what?)



What do I need to do for it to open as just sRGB in photoshop 7 so it doesn't open with the color management dialog box (so, it doesn't interfere with a batch)?

My workflow is
1. edit raw files in C1
2. process as jpegs
3. unsharp mask batch in photoshop, then saved with e_filename (images for print)
4. resize, watermark, save for web batch for images in 3. in photoshop, then saved with s_filename (images for web)

    Hello

    You are shooting in RAW not jpgs with sRGB profile.
    If you set the software to process files to "Embed camera profile" then it uses the Phase One camera profile which basically utilizes the entire workspace of the camera.
    If you want to work in sRGB (a quite small color space) then simply set the software to sRGB instead of "Embed camera profile"

    You can also simply convert the file in PhotoShop to sRGB but this requires one more step in your workflow which seams unnecessary.

    So, then is the Camera profile another profile like adobe rgb 1998?

    Maybe I should just use the camera profile (or would adobe rgb 1998 be better?) for the big images (for print) and then just add "convert to srgb" in the batch for the web photos?


    I was using sRGB because I read it's more versatile and all places can print in it. Do you think adobe rgb would be okay printed at Costco?

    dirt lover,

    All profiles are RGB profiles, except grayscale of course.
    Your in-camera color space setting applies to in-camera processed images - JPEGs
    In general, Color Space is your choice and depends on what images are printed with.
    For Web display, no matter what profile is used, it will display sRGB.
    Therefore, create sRGB images for Web.

    In general, Labs who use Fuji paper and chemicals get best results with sRGB
    Kodak labs can accpet sRGB but get better results with Adobe RGB (1998).
    To simplify, Adobe RGB is a bit warmer and little more saturated than sRGB.
    With consistency, great print color can be achieved either way.

    The COSTCO near me uses a Fuji Frontier printer.
    Not sure if All COSTCOs use Fuji.
    Go to Dry Creek Photo and you may actually be able to get the Printer Profile for the COSTCO near you.

    Color Management can be a very deep subject and a lot of time can be spent understanding it. It truly does not have to be complicated.
    Consistent and accurate color output is easy and possible with the tools and capabilities of Capture One.
    Whatever color space is set at Destination ( working space) is what the Thumbnails and Previews will be displayed in.
    Of course color doesn't mean much unless you've color calibrated your Monitor and loaded the file correctly.

    If you have PRO version, you can process a 72 Resolution sRGB and a High Quality 300 Res Adobe RGB file at the same time for efficiency. In fact, 3 different file types are possible outputs simultaneously.

    Hope this helps.
    Cheers,

    Thanks a lot for the help. I'll see what printer they have next time I'm there. I use a Pantone Huey to calibrate my monitor once a week. I have C1 LE.

    So, the output destination is 'convert to destination' in the dropdown menu and the web destination is the web destination in the dropdown menu?

    I set the output destination to Adobe RGB. Then I did the process with 'convert to output destination'. I looked in the jpeg properties and it says that is is sRGB. Am I doing something wrong?

    Also, to view the jpegs with adobe rgb correctly, will i need to set my monitor to Adobe RGB?

    dirt lover,

    If you are adjusting your own color, you need to get a monitor calibration program and create your own profile for your monitor.

    To Be sure you are processing the correct profile, At Color Management Settings:> Set Monitor Profile: to calibrated file, OR if you don't do this then yes, Adobe RGB
    > Output Destination ( Working Space ) Adobe RGB (1998)
    > Process tab > Color Management workflow: Convert to Destination

    With these set correctly, absolutely, positively, the resulting image will have this color space embedded in image file.
    If you look at your JPEG meta data and it show an sRGB color space, then this is likely the in-camera setting you have and NOT the true color space of image.
    Determine this in Photoshop.
