Lightroom displays your favorite profiles at the top of the Profile Browser. They also appear in the Profile menu in the Basic panel. This is a shortcut that means you don’t have to open the Profile Browser to access your favorite profiles. Tip: The Adobe profiles are marked as favorites by default.
What are the profiles in Lightroom?
Within ACR and Lightroom, a profile is used to render your photograph, converting it from raw camera information into the colors and tones that we see. For raw photographs, we build profiles for nearly every camera make and model we support (our DNG format enables camera manufacturers to build their own profiles).
What color profile does Lightroom use?
Lightroom Classic primarily uses the Adobe RGB color space to display colors. The Adobe RGB gamut includes most of the colors that digital cameras can capture as well as some printable colors (cyans and blues, in particular) that can’t be defined using the smaller, web-friendly sRGB color space.
