The values inside the new White Balance CC tag in evrExpanse 3.1.0 refer to the custom configurations for the Green-Magenta and Amber-Blue axes that can be set in-camera and then extracted and imported into NLEs for more accurate color grading and correction.
If the tag contains one value, it corresponds to the Green-Magenta axis. A positive value indicates a shift towards magenta, while a negative value indicates a shift towards green.
If the tag contains two values, it refers to both the Green-Magenta and Amber-Blue axes. The first value corresponds to the Green-Magenta axis, while the second value corresponds to the Amber-Blue axis. A positive value in either axis indicates a shift towards magenta or blue, respectively, while a negative value indicates a shift towards green or amber, respectively.
For example, a White Balance CC tag with a value of +5 would indicate a shift towards magenta on the Green-Magenta axis (GM:+5), while a tag with values of +5,-3 would indicate a shift towards magenta on the Green-Magenta axis (GM:+5) and a shift towards amber on the Amber-Blue axis (AB:-3).
