Thank you for your reply. After further analysis, it seems that this kind of histogram is to be expected. I think part of the confusion for me was because I initially assumed that the values coming from the camera will occupy the first 14 bits of the 16-bit range. They are instead spread over 16 bits. I recreated an histogram but this time without any debayering, so directly on the sensor data. In this case we can see that the values are always even numbers (at least most of them) and are spaced evenly on 16-bit range (between 0 and 65533). The gap between each value is 4 which is logical since only 16384 values are possible with 14-bit. I also went back to the histogram that I produced using the PhaseOne SDK and gaps were present too (but less obvious). In this case, they seems to use some kind of contrast correction which I don't have control over. So that's it, I suppose I just need now to divide the pixel values by 4 so all the data will be concentrated on the first 16384 values. Thanks again.
Сheck that the toolchain (autotools, libtool) isn't broken.
When the log suggests to run autoupdate, it may make sense to try it (after being sure toolchain is OK, and if the message re autoupdate still appears).
Suppose the image is N by M pixels, and you are dealing with Bayer sensor. How many pixels there are in each of four channels? Approx. 1/4 of the total number of pixels, N/2 by M/2.
I also tried autoreconf --install and then running configure.
I got:

I do not see a question here, so just a general remark.
Sony ARW 2.3 (lossy compressed) format is:
- 11-bit values (11 bit base + 7 bit deltas)
- expanded by expansion curve w/ ~0..16383 range (really slightly more)
dcraw converts it to ~0...4095 range, this is OK for old cameras but not for A7 series. LibRaw uses 'natural' camera range.
I also seem to have another issue with FUJI XT4 raw RAF file. When decoded to HALF and FULL, both works fine. However when I enabled FBDD denoise, the decoded image came out incorrect.
once I "make -f makefile.dist", how am I supposed to use the libraw/rawspeed compiled code with my code?
Makefile.dist does not contain any reference to CMake/CMakeLists.txt so I do not know what the problem source is, sorry.
Hi Alex,
Thank you for your reply. After further analysis, it seems that this kind of histogram is to be expected. I think part of the confusion for me was because I initially assumed that the values coming from the camera will occupy the first 14 bits of the 16-bit range. They are instead spread over 16 bits.

The gap between each value is 4 which is logical since only 16384 values are possible with 14-bit. I also went back to the histogram that I produced using the PhaseOne SDK and gaps were present too (but less obvious). In this case, they seems to use some kind of contrast correction which I don't have control over. So that's it, I suppose I just need now to divide the pixel values by 4 so all the data will be concentrated on the first 16384 values. Thanks again.
Could you please provide RAW file sample for analysis?
BTW, 'minimum processing done' is no processing at al. Consider use LibRaw's unprocessed_raw sample or RawDigger.
Do you see Hasselblad X2D 100C in LibRaw 0.21 supported camera list?
Thanks guys for this great library!
I have added it to my Photo Management application Tonfotos: https://tonfotos.com
By the way, is there any progress with this "Used by" initiative? I think that is a great tool to promote LibRaw.
Just in case, Tonfotos logo can be found here: https://tonfotos.com/img/logo/icon-ui.webp
Regards,
Andrey
It is supported in LibRaq 0.21-beta available at github (we plan to release it in a month or so)
Any estimated timeline when Canon EOS R7 raw will be supported?
I'm in the same situation too. Did you find any solution to your problem?
Oh, I see. Thanks for the information.
Yes, dt (again) uses LibRaw but (AFAIK) for Canon CR3 files only.
Please contact dt team for details.
Сheck that the toolchain (autotools, libtool) isn't broken.
When the log suggests to run autoupdate, it may make sense to try it (after being sure toolchain is OK, and if the message re autoupdate still appears).
OM-1 is supported by this commit: https://github.com/LibRaw/LibRaw/commit/adcb898a00746c8aa886eb06cc9f5a1c... (dated Mar 13, 2022)
Suppose the image is N by M pixels, and you are dealing with Bayer sensor. How many pixels there are in each of four channels? Approx. 1/4 of the total number of pixels, N/2 by M/2.
You can run dcraw_emu from the command line to convert raw to bitmaps, please have a look at https://www.libraw.org/docs/Samples-LibRaw.html
>what you mean with more detailed measurements?
Something like detailed performance profiling (with any avail. tool). The question is: what function is slower in v 0.20 compared to 0.19
Thanks for your response,
But I would like to know what you mean with more detailed measurements?
So the behavior is quite ok-ish ? And depends on image 19.2 or 20.2 can win the race?
Thanks in advance.
I also tried autoreconf --install and then running configure.

So bad that none has replied so far... I've tried to find any answer around the internet but couldn't much.
Anyone?
L.S.,
Would you please be so kind as to add support for RAW files (.ORF) files of the OM-systems OM-1 camera?
Thank you in advance,
Jan.
I do not see a question here, so just a general remark.
Sony ARW 2.3 (lossy compressed) format is:
- 11-bit values (11 bit base + 7 bit deltas)
- expanded by expansion curve w/ ~0..16383 range (really slightly more)
dcraw converts it to ~0...4095 range, this is OK for old cameras but not for A7 series. LibRaw uses 'natural' camera range.
Please make sure EOS R3 and R10 are listed as supported in the snapshot you use.....
Hi Alex,
Sorry for the late reply. I have since figured out my mistake. (basically I built the wrong checkout on my computer)
After I corrected my build mistake. the latest checkout works with R5 raw (both compressed and non compressed cr3).
It still have problem with cr3 files that are came from EOS R3 and R10.

I also seem to have another issue with FUJI XT4 raw RAF file. When decoded to HALF and FULL, both works fine. However when I enabled FBDD denoise, the decoded image came out incorrect.

Thank you for your effort.
Both bugs are 'garbage in/garbage out', so no plans to fix these bugs
Could you please specify EOS R5 files that are not processed right with 202110 snapshot?
