When using Capture One readouts to critically compare the numerical values of a color chart (i.e., a reflectance target), it is important that the standardized light source used for the chart’s values is the same as that used during capture because the chart's color values for a certain RGB color space are based on the illuminant. Therefore, before measuring RGB values, it is important to adopt a similar working RGB space to the chart's RGB color space values. In Capture One, this is the output color space in-effect and is determined by the selected Process Recipe by default. Although this is initially selected from the list in the Process Recipes panel, the actual parameters used to process the results in the Viewer and for eventual output as a processed image are displayed below in the Process Recipe tool.
- Go to the Output tool tab.
- From the Process Recipes panel, select the required recipe from the list. The Process Recipe panel beneath is populated with the selected recipe's parameters.
- From the Process Recipe's Basic tab, verify or select the required RGB color space profile from the ICC Profile drop-down menu. For example, select the same RGB color space profile (e.g., sRGB) as the color space specified for the values in the color chart’s documentation.
