I feel there's a tremendous amount of misinformation about LOG gammas, how they supposedly give RAW like dynamic range. So I've been working on stuff to clarify it. Anyway, this is another proof of just how great ML! How else could I create RAW DNGs at 640x360 resolution! Like all my videos, I wish it was better, that I had more time, but I hope it will help someone out there get beyond the hype of S-LOG, V-LOG, etc.

BTW, took a long time to figure out how to pull out integer values from a DNG file, so, in case there are other slow people here like me:

Code Select

import rawpy
import numpy

raw = rawpy.imread('D:\\M08-2120_000520.DNG')
rawdata = raw.raw_image
numpy.savetxt("D:\\dng520.csv", rawdata, delimiter=",")
