  • After the photo is taken, it increases brightness of the raw file by 1/3 stop (with a linear digital push)



So it is the opposite direction from what Jan and I were saying...


But then, don't you lose 1/3 stop in the darks instead of in the highlights? Doesn't doing a linear digital push leave you with no data at the low end of the raw file? Or do you mean you lose 1/3 stop of highlight headroom as compared to iso1600 underexposed by 1/3 stop (but not as compared to a "correctly" exposed picture?


Anyway, it bad.


If canon would just leave the raw alone, the world would be a better place.
