  • rgb cmyk channels

    Clicking on the channels layer will normally give you the red green and blue channels layers.

    I forget how to get cmyk layers and how to get both cmyk and rgb layers all in the same channels list. How do i go about doing this?

    I hope this makes sense. Anyone?

    Kyleb, if you want to view or work on CMYK channels you need to convert the image from RGB to CMYK. If you use PS, then do Image>Mode>CMYK

      you cant have CMYK and RGB layers all coexisting in the channels panel at the same time.

      But they do both show within the same channels panel just one at a time, depending on which one you have selected, which Murray showed you.

            That's cool, thanks!

            Reminds me of a channels-based creative tip:

            Convert your image to CMYK, blur the K (black) channel using Gaussian Blur, switch back to RGB. Nice dreamy effects.

                There is even a book or two on channel chops (including one by Scott Kelby).

                  I often duplicate the RGB channels before converting to a CMYK profile. This can give me more options when channel masking.

                  You can also do this in reverse if you work with a duplicate of the file, duplicate channels and move them between the two different colour modes. I generally only do this when I don't want to narrow the gamut by converting to CMYK, but still need the detail that sometimes RGB can't give me.

                    CMYK mode. Then CMY channel become too faded
                    (blurr, ghosty) and patchy but black channel looks fine.

                    I've noticed several of the Challenge entries mention working in CMYK mode. This intrigues me, since the originals and destination are both RGB.

                    Is it simply a case of working in the mode you're most comfortable with, or are their more pragmatic reasons for converting?

                    Hi All again,

                    I saw a thread in a few days, about photo like this picture but I can't find it. When I changed this picture to cmyk (profil EuscaleCoated v2.). I've lost the detail of light at the upper right, as U see. I tried some other profile but it was the same. Can someone help to...

                    Converting CMYK to RGB and back to CMYK.
                    by xxxmen
                    Hello all,

                    I'm aware that RGB is a larger gamut of colours then CMYK. If I had an original image that is given to me in "CMYK" when using Photoshop for colour correcting; is there any loss in quality if I convert the CMYK image to RGB.
                    The reason for converting to RGB...

                    RGB or CMYK?
                    by ekuna
                    Should it matter to the retouching house if I work in
                    RGB or CMYK? You can always convert the mode - is it
                    such a big deal?
