irieger: how did you get 6-7 stops? on colorchecker_gainx2_15ms_01.raw12 you have white level around 3300, noise in the darkest patch (which isn't quite black) about 5.5 (stdev), so log2(3300)-log2(5.5) = 9.2 stops (probably underestimated, since noise wasn't sampled from a black area)

in my Alpha tests, at gain x2, DR was about 9.5 stops - https://dl.dropboxusercontent.com/u/4124919/bleeding-edge/apertus/snr-curve/snr-gain2.png

alexML: I did an exposure series on a exposure chart. I'm currently verifying some stuff. But the DNG sequence I shot with my reference cam (Blackmagic Production Cam 4K) was around 11 stops so I'm not totally wrong with the process. Maybe I just fucked up some sensor settings or so

at least currently. Easiest way to have a pseudo interactive way to analyse the data
