Hiya…
can some one please confirm what matrix would convert a
- Linear srgb (cg)
to
- Linear REDLog3G10 (converted to linear via OCIO 1d)…
This is to comp cg in nuke with working space of red Linear.
Is this Correct Please?
from ocio:
Input - RED - Linear - REDWideGamutRGB
[0.785043, 0.083844, 0.131118, 0, 0.023172, 1.08789, -0.111055, 0, -0.073769, -0.314639, 1.38854, 0, 0, 0, 0, 1]}
p.s. I understand that ACEScg would be a preferable working-space, but we have already started the show.
thx. rafal
Hi Rafal,
No this is incorrect, the matrix (assuming you want RED Wide Gamut RGB) would be as follows:
[[ 0.5419710236 0.3601646194 0.0979367359]
[ 0.0769296461 0.7680017846 0.1550375610]
[ 0.0588396717 0.2735065260 0.6676122457]]
You can compute them as you wish using this App: https://www.colour-science.org:8010/apps/rgb_colourspace_models_transformation_matrix, https://www.colour-science.org/apps/
Cheers,
Thomas
