Ok, but how to get raw histogram when viewing photos, and not just after the shot?

General Help Q&A / Why raw histogram seems to be not "raw"?
April 19, 2014, 07:02:04 PM
Hello everybody.
Small explanation: I'm using UniWB for some years, because it is much better to ETTR on Canon, and UniWB does great help with it. But also it annoys a lot, because often it is hard to see if the subject is in focus or not, and something more.
Some time ago I've discovered ML, and saw that it has Raw histogram feature, that should help me both to get out from UniWB and to make ETTR even more precise.
Month ago really non-desctuctive build was made (I mean bootflag on 5d mk III), and today I installed the latest nightly build.
I believe I've set all preferences required to see raw histogram, but the result is disappointing: when I call ML histogram by pressing "Light" button, very small histogram appears in the right bottom corner, and it is built using WB. I'm sure it is so, because I've shot two shots of the same scene that have the same A\S\ISO settings, and histograms are completely different.
So the question is: what I'm doing or understanding wrong? Is the histogram really built from raw, and is it possible to make it WB independent (and bigger in size, but it is less important).

Modules Development / Re: Dual ISO - massive dynamic range improvement for 5D3 and 7D

Dears, I'm sorry for maybe stupid question, but I really want to know..
Is it possible to read one shot twice? I mean - read sensor at iso 100, save it to buffer, and immediately read the same data at iso 1600? For CCD sensors it is definitely impossible, but for CMOS sensor it is not so obvious. So could you please help me?
