Creating Camera Profile?

littlemike
Hi,

I'm using a 20D and CO Pro. I have some shots of my GretagMacbeth colorchecker card that I used to set Adobe Camera Raw for better color. Is it possible to create a profile for similar use within CO Pro?

    Capture One can easily use ICC profile files. A program called inCamera by PictoColor will make ICC files from GretagMacbeth shots.

    Mike,

    Using the Color Editor of PRO version, you can create your own custom profiles in Capture One.

    Workflow > Color Editor > Load the 20D generic profile and make adjustments and then Save As... your own custom 20D

    The Color Editor can also be used to adjust selected color within an image.
    Use the eyedropper to select color from image, and then enlarge or reduce on color wheel and adjust.
    The display in lower left will show before/after change in color.
    Save file to be applied in Color Management.
    For images that require dead-on color, this tool is invaluable.

    Cheers,

    Thanks, Keith

    I'm finding Color Editor to be less intuitive, or less flexible (I can't tell which) than the tools in Adobe Camera Raw. The calibration technique I used in ACR is here:

    http://people.csail.mit.edu/ericchan/dp/acr/

    After setup, the first step is to linearize the gray scale (bottom six patches on the bottom of the chart). The method shown for ACR makes this pretty easy, but Color Editor does not seem to have enough "power" to swing the rgb values to where they need to be. For example, the patch on the bottom, second to the left, should be 190, 190, 190, but my photograph of the color chart gives 201, 199, 197. Sliding the "lightness" slider all the way to the left gives 198, 196, 194. Not enough bias.

    On the other hand, the second patch from the right on the bottom should be 67, 67, 67, and my image is 70, 68, 68, which is correctable with the Color Editor tools.

    In a similar fashion to the first gray example I gave, the colored patches, such as second row up, third from the left, which should be 122, 58, 46, photographed as 150, 59, 46 and none of the controls let me lower the r value anywhere near the target 122 value.

    What's up?

    Hello? Testing, testing. Is this thing on?

    No further help on this question?

    Mike,

    Yes this User to User Forum is always on.

    Remember, the most efficient way to obtain Technical Support is to Create a Support Case at the Support area of the web site:

    http://support.phaseone.com

    You may need to create a Camera profile and a WB file to reuse for your Sessions. Using the 2 may get your values closer to desired.

    If Painting by Numbers for your printer, lab or customers is a must in order to have precise numbers, then you should use the program that gets you these exact values. Hard to imagine there is anyone with a discerning enough eye to see difference between 67, 67, 67, and 70, 68, 68 - but I also know there are some very critical customers out there 😉

    And yes, I do see a slight difference on my monitor between colors with these values.

    Regards,
    k c

    Well, that was kind of a slam to selectively pull fro my post the the dark gray gray chip that should have been 67, 67, 67 and which measured at 70, 68, 68, an error which I said was correctible with Color Editor, and call what I am looking for "painting by numbers," while overlooking the red 122, 58, 46 patch that photographed as 150, 59, 46 -- enough variance that even Stevie Wonder would see it.

    ACR's tools allow a fellow to correct for those kinds of color errors.

    It's not clear to me if this is a support question, or whether I am expecting something from CO Pro that it does not provide, so here's my bottom line question:

    Given the variances in the color chips that I am measuring, is this something that I should be able to correct with the color editor, or are these variances outside its range?

    If CO Pro should be able to adjust out those errors, then I'll open a support case. If CO Pro cannot, then I'll keep that in mind and see about having someone create a custom icc profile for my 20D.

    Maybe a help, maybe not...
    Have you tried these profiles? http://www.etcetera.cc/
    The 20D is listed.

    Mike,

    No, Capture One does not have the ability to create a Custom Camera Profile for your 20D.

    There are programs or consultants that can do this for you.

    If you do this, you will want to process a RAW image file to TIFF and have the
    Phase One - No color correction profile selected at the Camera Profile in Color Management.

    Capture One has color management capabilities to get consistently good color results in the workflow.
    When absolute accurate color is needed, i.e. a product color or a sports team uniform, where precise color is a must, then a custom profile for your camera should be created.

    Cheers,

    Thank, Keith -- that's all I needed to know! I like CO, just needed some help figuring out what its capabilities were w/r/t color correction.

    Thanks, Matt -- I'll give 'em a try!

    Thanks for that lead, Christopher. "Paint by numbers" (as Keith puts it) is not my goal, but good tools should be able to achieve color fidelity if such is desired.
