It may need to be updated to work in current Company version.

@snibgo Thanks a lot for your detailed instructions. I understand the principle of your approach. But it will take a while till I understand exactly what the script is doing.
@anon41087856 and @sguyader thanks for pointing out which other tools may help me.

Another thought: hereās a gain-and-bias result:
This tweaks the RGB channels, giving each a multiplier and addition to make the mean and standard deviations match the target. This is simpler than the match-histogram method, and the result is fairly good. When the range of input colours is small, it is more reliable than match-histogram, so might be better for a method that chops one image into tiles, finds the tiles in the other input, matches pairwise, then blends the results.
My command was:
call %PICTBAT%imgGainBias ^

ā¦ where imgGainBias is at Gain and bias.
Ciao, Gabriele!
Unfortunately: no
Have fun!

Iām searching an FOOS for a Rawdigger alternativeā¦ Do you have any hints?
You could try HISTOGRAMMAR V1.2 2011 HISTOGRAMMAR V1.1 on Guillermo Luijkās homepage. GUILLERMO LUIJK >> PROGRAMAS >> HISTOGRAMMAR
YMMV in using it.
I do my raw inspection in Mathematica, because so far I have never really bothered to learn Python. If you know Python, you could use rawpy Ā· PyPI which utilizes libraw to import your files and try to find what youāre looking for.
If I understood itās for windows only ; Iām on Linux
Have you any hints?
Ah sorry, didnāt know you were on Linux. In that case Iām afraid I cannot help you out. What is it you want to do exactly?
I was curious to analize my RAW histograms more in details: view single sensor bin (R,G1,G2;B)ā¦ I know I can find into RT with no demosaicing and the inspectorā¦but
Iām amazed in the FOOS there isnāt a software as Rawdigger
Iāve taken up the endeavor a couple of times, but put it aside as more pressing programming arose (sounds more āofficialā than it is, really about what I felt like doing day-to-dayā¦ ), Really, I put a bit of work into rawprocās histogram, and it meets my needs rather wellā¦
I have put some time into a command-line program thatāll read a raw file courtesy libraw, then walk the image array, collect and sum the channel data per value, and puke it out as comma-separated text suitable for opening in your favorite spreadsheet program. Libreoffice makes a nice histogram of the data with itās column chart. Works okay on my test raw, but itās not easily compiled by non-programmers in its present state.
Really, Rawdigger isnāt such a commercial abomination; it helps fund libraw, the open-source core library that some of us use in our raw processing programs.
Indeed I agree with this, but:
RawDigger is a microscope of sorts that lets you drill down into raw data both on Mac OS X and Windows.
Didnāt realize that. Danged GUIsā¦
Now is your chance to make a Linux version and call it āRaw Butcherā
Well, I almost have one, if you donāt mind your GUI being LibreOffice/Excelā¦
I can draw you a clever icon
Hi Glenn,
we are waiting
PS. Idea ā¦ and if RT ( because itās capable to make RAW histogram but in the 0-255 range for gui and velocity needs) could export a RAW histogram scale 1:1 ??
@dafrasaga Gabriele, you might find this interesting: Improvements to change main histogram to 65535 bins by Thanatomanic Ā· Pull Request #5904 Ā· Beep6581/RawTherapee Ā· GitHub
The wish is to include this change for the 5.9 release of RT, but it needs some polishing up first.
Good
