There is a variety of color spaces.
Color Output Settings
Capture One Express can output to any RGB color space while Capture One Pro can also output to CMYK (it is necessary that the ICC profile is available on the local machine).
Images that are intended to be published on web sites should always be processed into the sRGB color space as few web-browsers are capable of color management and the subtleties of images will not only be lost but can also be incorrectly displayed. Images processed in larger color spaces like Adobe RGB will be displayed with less color (especially green) and those are often slightly too dark when shown in browsers that support only sRGB.
Images for print should be output to suit the requirements of the client or lab. Adobe RGB is a large color space that is capable of expressing a wider gamut of colors than sRGB. Adobe RGB is the preferred choice for images that are likely to receive extensive processing or retouching.
Embedding the ICC color profile into the processed file (ICC Profile -> Embed Camera profile) ensures that no color changes are made to the image data, which is particularly important for creating camera profiles.
Image files that are intended to receive intensive retouching and manipulation can benefit by being processed and output in 16-bit to ProPhoto RGB, which is a larger color space than Adobe RGB.
CMYK Color Spaces
Capture One Pro provides a selection of the most common CMYK color spaces. The photographer can convert to CMYK during processing to ensure image quality instead of applying this color space conversion in postproduction. CMYK can be selected in the Output Tool Tab.
Setting a permanent color space in Capture One
Capture One Pro allows you to proof color space profiles, including CMYK, for output prior to being processed. Alternatively, as Capture One displays the image in the Viewer using the ICC profile that’s selected in the highlighted Process Recipe, you can use a recipe to display the color space permanently. Note, a permanent color space profile seen in the Viewer may produce different colors than the actual output image.
- Select View -> Proof Profile and select the desired profile from the list.
- Perform final corrections before processing by using a recipe with the desired profile.
- Alternatively, select the desired ICC profile in a Process Recipe for the permanent display in the Viewer.
