Auto-ETTR is performed on output stage, while converting from linear internal representation to gamma-corrected output in LibRaw::write_tiff_ppm or LibRaw::copy_mem_image
Thanks. I tried different combinations of the options in the list you linked, but no luck.
Can you point me to where I can access settings for Auto-ETTR in the source code?
Hello. Are you able to provide an estimate for when the next snapshot will be (I’m assuming the next snapshot will add support for recently released cameras like Fuji X-T5, X-H2, Sony A7R5, etc)?
Yes, this should(*) turn off auto-ETTR/auto-scaling, so this will result into dark(er) images.
(*) we're not responsible for AndroidLibRaw so not absolutely sure set....() calls works as expected.
I use the unofficial Android port https://github.com/dburckh/AndroidLibRaw
which should apply the options:
no_auto_bright = true
no_auto_scale = true
Could you please clarify: you use LibRaw library from your application, or some LibRaw sample programs 'as is' (as a command-line utility)
I'm also struggling with this. Can you point out which command do I need to use to turn it off?
It was tagged while creating release files downloads for this site, export script works on tags.
Github release was created on your request
Great, thank you. It looks like you tagged it earlier today. I use the cmake repo for building so the missing configure is not a big deal.
Already tagged: https://github.com/LibRaw/LibRaw/tree/0.21.0
Official release is available via this site download section: https://www.libraw.org/download
Github release has been created too: https://github.com/LibRaw/LibRaw/releases/tag/0.21.0
(although github release does not contain generated ./configure script)

rgb_cam is used to construct camera to output RGB matrix: https://github.com/LibRaw/LibRaw/blob/master/src/postprocessing/postproc...
Cmatrix is the same, it may be copied to rgb_cam if corresponding params option is set and the matrix is not empty: https://github.com/LibRaw/LibRaw/blob/master/src/metadata/identify.cpp#L...
Spot on! 0-21 works perfectly.
Thanks!
Could you use a more recent LibRaw version?
https://www.libraw.org/news/libraw-0-21
You can run dcraw_emu without parameters, and also have a look at https://www.libraw.org/docs/Samples-LibRaw.html
On a side note, exposure is measured in lux seconds.
anything I can do via options in the binaries? Any pointers on where to start would be great. Thanks.
dcraw (and, so, LibRaw) standard processing is 'auto-ETTR', there are a lot of option to change it.
Does your software vendor tell you that your camera isn't supported because of LibRaw?
If so, have they tried to contact us?
> I’m assuming the next snapshot will add support for recently released cameras like Fuji X-T5, X-H2, Sony A7R5, etc
Please don't assume.
Sure, at our News section of this site.
For example: https://www.libraw.org/news/libraw-0-21
Are the release notes publicly accessible and do they offer a list of camera updates, by chance?
We plan to release 0.21-release this month.
Public snapshots are published every 7-9 months: https://www.libraw.org/#updatepolicy
Hello. Are you able to provide an estimate for when the next snapshot will be (I’m assuming the next snapshot will add support for recently released cameras like Fuji X-T5, X-H2, Sony A7R5, etc)?
I think you may suggest them to contact us, for a start...
1-4-6 beta definitely works. Does this mean that the GH6 .RW2 format will be supported in the next version? Is there an ETA on that?
If a company like Affinity is using LibRaw as a part of their developing engine, what can I do to let them know it is ready to be incorporated?
