In the dialog that pops up when you deliberately convert an image from one ICC color space profile from one to another.These default profile conversion intent settings are used to display images on your monitor screen.
In your image editing software's Preferences/Color Management Settings ("Color Management Settings" for short) dialogs, where you can choose the default color conversion settings.
The table has three major column groups because color-managed image editing software typically allows you to set ICC color space profile conversion options in three different places: The table below summarizes the ICC profile conversion options for Cinepaint, GIMP, Krita, and digiKam/showFoto (henceforth sometimes referred to simply as "digiKam"). Table Summary of the GIMP, Krita, digikam/showFoto, and Cinepaint ICC profile conversion options digiKam/showFoto Color Management Settings (valid at least through digikam 4.7): digiKam/showFoto color management settings are under "Settings, Configure showFoto, Color Management", under the "Profiles" and "Advanced" Tabs (shown above also see digiKam/showFoto Settings for Color Management: Behavior Tab"): the digiKam/showFoto "Advanced" tab is where you choose the default color conversion intent and also whether or not to use black point compensation. Note: the Krita settings changed perhaps by Krita 2.6, adding some additional and very useful options. Potential issue: To access the Krita Color Management Settings settings dialog requires opening an image first otherwise the "Configure Krita" option does not appear under "Settings". (GIMP 2.9 from git provides for black point compensation.) Krita 2.4 Color Management Settings: Krita color management settings are under "Settings, Configure Krita, Color Management". GIMP uses black point compensation when "relative colorimetric" is chosen as the Display (default) rendering intent, and does not use black point compensation when "perceptual" is chosen as the Display rendering intent. Potential issue: Unlike the other image editors, GIMP does not provide a check box for choosing whether or not to use black point compensation. Notice that GIMP specifically says " Display rendering intent"). In this screenshot, I've set GIMP up to use a matrix monitor profile. GIMP 2.8 Color Management Settings: GIMP color management settings are under "Edit, Preferences, Color Management". I compiled Cinepaint from source and was not able to get the Oyranos plugin to work, which is fine with me as I find the Oyranos settings to be completely unuseable: The Oyranos settings seem designed to enforce particular sets of color management choices based on "per task" settings that just aren't applicable to an individual artist working in his or her own personal digital darkroom. Potential issue: There are additional Cinepaint options to consider if Cinepaint has been compiled with Oyranos support. In this screenshot, I've set Cinepaint up to use a lookup-table monitor profile created specifically to display sRGB images. Screenshots of Cinepaint (valid for all versions not running Oyranos), GIMP-2.8, Krita 2.4, and digiKam/showFoto Color Management Settings dialogs (valid at least through digikam 4.7) Cinepaint Color Management Settings: Cinepaint color management settings are under "File, Preferences, Color Management".
If you don't know what a conversion intent is, see ICC Profile Conversion Intents. The different image editors all have their quirks, so you might want to skim the notes that pertain to your preferred image editor. If all you really want to know is "what settings should I use", see Table Note A. I don't have any plans for updating this page any time soon, so bear in mind that the Krita 2.9 (and I believe as far back as Krita 2.6 or 2.7) settings aren't exactly the same as Krita 2.4, which was current in 2012. GIMP 2.9 from git (but not GIMP 2.8) does now allow the user to choose black point compensation.Īs of March 2015, GIMP 2.8, Cinepaint, and digiKam/showFoto Color Management Settings (through digiKam versions 4.7) haven't changed since 2012. In particular, Krita settings have changed slightly (for the better, I might add, but as of version 2.9, Krita still doesn't provide for soft proofing and also still doesn't allow the user to assign a new ICC profile to an image). Some of the information on this page is outdated.
