  • Differences between the preview and the output image
    The color-managed preview in RawTherapee is (and has always been) based on image data in the Working Space profile. Although the actual preview is rendered using a monitor profile (or sRGB profile, if the monitor profile is not specified), it does not reflect the Output Profile & Output Gamma settings. This can lead to a slightly different output rendering when Working Space profile and Output Space profiles are not the same. A workaround is to set them to the same values to ensure the preview accurately reflects the final rendered output.
  • For generic use in an sRGB workflow when the output target is web-based image display, it is recommended to use the default values of the Color/ICM toolset (Working Profile = sRGB, Output Profile = RT_sRGB).
  • Future releases of RawTherapee are planned to support a more comprehensive color-managed preview that will allow proofing with accurate visualization of the final output render based not only on the working space and monitor profiles, but also on the user-selected Output Profile and Output Gamma.
