The problem: I wanna merge

The problem:

I wanna merge some raw files, but output is linear, with 16 bits (that's the most you can get into the DNG) achieving a useful dynamic range up to about 13 stop, so from the shadows you got posterize (in this article explains:

So would be good to investigate whether the DNG support encoding data in a nonlinear way. If this is possible, then these 16-bit DNG nonlinear will has a big..big.big dynamic range, like 20 stops or more, which neither exists in the real world ).

I thing that a linearization table (LUT) will be the solution to this.

I wanna "merge" raw files, before demosaicing for obtain the lowest noise.
