It is supposed to work (better) with the following filter expression, the
values taken from {{{ffmpeg -i}}} output but it is apparently wrong for
this sample:
{{{-vf 'lutrgb=r=777*val:b=408*val'}}}
A simpler alternative is {{{-vf histeq}}} but this doesn't work well
either.
The following looks better here, do you agree? (I may just misunderstand
how it works...)
{{{-vf 'lutrgb=r=1.777*val:b=1.408*val'}}}
