I have finally got a good HDR to SDR conversion using DGHDRtoSDR_1.12 by accident instead of 1.13
You see the light argument finally got the converted SDR to light levels matching original SDR!
I work in stax and this finally after years of trying tools works with good results.
Code: Select all
z_ConvertFormat(pixel_type="YUV420P16",colorspace_op="2020ncl:2020:2020:l=>709:709:709:l", dither_type="None")
DGHDRtoSDR(light=150.0, impl="255", fulldepth=true )
Maybe I am silly but I could not get the white and black arguments in 1.13 to match the results of using light in 1.12 at all.
I'd post image examples but don't want to get anyone in trouble.
P.S. Donald, I owe you a license which I will happily do now that I got it working.
