Profiles are camera nodel-dependent, and if you're very picky, dependent on each camera so you create profiles for each camera.įree software like Rawtherapee may take a far longer time to fully support a camera - that's why it advises about "If you have an ICC or DCP input profile for your CR3-producing camera, you will need to point RawTherapee to it manually (Color tab > Color Management > Input Profile > Custom)." More that one profile can be made for different kind of images. Styles/profiles remap those data (like ICC profiles do) to deliver a good starting point - especially contrast and saturation. Demosaicing rebuilds each pixel RGB data from the Bayer array, but those are still raw data. Without them, RAW data usually look flat and desaturated, because they have much more data than any screen can display, and don't store data like the human eye expects. That's because DPP and other tools apply after demosaicing what DPP calls "Picture styles" and Lightroom "Camera Calibration Profiles".
