  • Color management question

    Hi,

    This is my first time posting but I love the website and have learned a lot from reading the forums...I have a long way to go with my retouching.

    Ok, my question. I think I know the answer but just want some confirmation. After watching the color management tutorial last week, I switched Photoshop to ProPhoto RGB. However, all my images are in Adobe RGB.
    When I open my pics I get a warning...can/should I convert the images to the new profile without harm? Can I go from a smaller gamut to a larger one?

    Thank you,
    Kyriakos

    Kyriakos, welcome to RetouchPro. You can convert from AdobeRGB to ProPhoto but it is a little like adding a decimal point and 4 zeros to a number that you had already rounded off to an integer. If the original image was captured in a very wide gamut device, the extra information would have been clipped when it was converted to AdobeRGB. If your plan now is to edit that AdobeRGB image and output to someone or some device in an color space with a smaller gamut than ProPhoto, then I see no value to make the conversion.
    BTW, you are wise to have turned on those warning boxes in the Color Settings.
    Regards, Murray

            Zero reason to convert from Adobe RGB to ProPhoto (and some good reasons not to). Once you’ve rendered an image in a color space, going from a smaller to larger space buys you nothing unless you have to composite data together (then you have to in order to maintain the color appearance). Going bigger to smaller, no issue.

            This may help:

                I think it depends on what image files you are talking about. If you are referring to jpeg images, the answers above apply.

                However if you are talking about RAW image files (where the camera has been set to produce AdobeRGB output), the RAW files are unaffected by this setting. If you are using Adobe ACR to convert the RAW files it is a simple matter to set the output of the converter to ProPhoto and then it will cause no confllict with your chosen workspace in Photoshop. You will benefit from the larger color space and, if necessary, you can later convert to a smaller space on output.

                  by jam1212
                  Hi all,

                  I've recently gotten a bid at doing some retouching for a wedding photographer. I'm going to be working on a few images as a test of sorts to see if I get the gig or not.

                  So, here's my question. My workflow currently involves opening the RAW files in ACR, doing...

                  Color picker/RGB values question
                  by Andymania
                  I have bee messing around alot with the color picker, color sampler tool and Info palette lately. Now, for example if I have a very, very dull red which can be something like R=98 G=50 B=45, photoshop would categorize this as a red since the R value is the highest correct? I am asking this because when...

                  Question for retouching/print professionals
                  by Maven
                  I am currently working on images that contain a neon color.

                  The client has given me this color information :

                  Volt = 71R , Black = OOA

                  Can anyone please explain what this information means?

                  Thankyou for your time!

                  Color Space - Are you seeing the real picture?

                  If you visit some of my entries you will find I usually begin by opening my images into "AIM RGB = Trinitron D65 G1.00" color space. If you're curious about what this means I'll try to explain in general terms what this is all about....
