Libraw settings

To final colors (a bit like lut applied):

dcraw_emu -6 -T -H 1 -q 3 -n 0 -fbdd 0 -m 19 -c 0 -g 2.2 12 -b 1.5 filename.dng

I have used this to make clean green screen plates.

This produces clean flat images that can be used to build 2.5K ProRes that can be e.g. graded in FCPX using wvl_Colograde2.

/usr/bin/dcraw_emu -4 -T -H 1 -g 2.7 0 -m 19 -n 0 -o 0 -b 1.5 filename.dng

I have also experimented with dark frame for noise reduction

/usr/bin/dcraw_emu -4 -T -H 2 -g 3 0 -m 19 -n 100 -q 3 -fbdd 1 -o 0 -b 1.0 -K /usr/bin/bmccdarkframe.pgm
