4.5.6 Grading Recommendation in “Extended Range” Mode
In order to reduce the reciprocal influence of the controls, it is recommended to start
adjustment with Gamma, then do Black and finally White.
With Master Gamma (0 - 2.5), the peak level of the “saw_14 test signal” can be
changed from 42% up to 100% and down to 7.5%.
MASTER Gamma 0.5 - 2.5
RGB Gamma " 60%
Fig. 416:
In “normal range”, Master gamma addresses only the grey values of a film scene
and changes not the black and white levels.
In “extended range”, Master gamma also changes black and white.
RGB Gamma changes the Master Gamma value between 40% to 160%.
After gamma adjustment, it is recommended to adjust the black level with the Black
controls RGB and Master close to 0%. Note that in extended ranges the Black con-
trols also affects the white level.
Both, Black Master and Black RGB can be changed in the range of 100%, but
the sum is limited to 100%.
