Reference Manual ATOM one SSM500

Note:

Instead of using the

lut_fixed_mode command,

consider using the

log_mode

which adds an internal gain adjustment for the HLG curve, a maximum brightness setting
for the PQ curve and a master gain setting for the S-Log3 curve. See chapter 8.17 for
details.
