Can you elaborate on the bug you're talking about. I know something is wrong with my false color tool (It shows yellow, orange and red ONLY from 2500 iso and higher. If I lower the iso by 1 stop and open the lens by the same 1 stop I incomprehensibly loose red, then orange, then yellow. 800 and lower, straw will always be the "hottest" color regardless of how heavily I am overexposing). And I know something is wrong with my histogram, as it starts adherent to the left goal post but ends "black on black" instead of going adherent to the right. And it ends differently if meta iso are 320 or 800, and so on.
No real problem here. Raw noise and stoplights indicators used in conjunction with exposure tool let me have a good idea. And is getting obviously better day by day, as I'm experimenting the camera directly
But the bug you're referring to worried me.
Is it only the exposure tools that need a little tweaking from you're side, or I am actually missing some real bits of latitude of what the camera should be able to let me use??
It's most likely a data representation issue, not an actual sensor latitude issue.Originally Posted by Alvise Tedesco;990449And I know something is wrong with my histogram, as it starts adherent to the left goal post but ends "black on black" instead of going adherent to the right.

What I am saying is, right now, the full width of the histogram represents the full range of the sensor. HOWEVER, depending on the curve you apply to the data, you may never actually see the full range plotted to the histogram.
BUT, If a linear curve were applied to the data, you would see the full range of the sensor in the histogram
Hi Matthew, so I tried it out. And I guess it's just the bug which is confusing. As for the blacks it works as you mentioned. Put a lens cap on, and when the screen goes dark black (RG3) , the histogram goes all the way to the left cut of by the bar, which - with the same picture - isn't the case in RLF, where the Histogram ends a bit further in (to the right) as is with RG2. Which makes sense, cause the screen turns grayish.
But with the highlight it behaves differently. Which is probably the zeroing of the curve as you mentioned. It should probably be all the way up in total white situations, what it isn't. But still it's confusing a bit that the total sensor range can be reached with blacks but never with the lights.
I found that switching to RedLog in RCX (not RedLogFilm) seems to be the only one that gives an accurate histogram reading. If we could enable this in camera, it would be solved!
Btw also with the new firmware (both 3.0.7 and 3.2.8) same issues here
