Just guessing, but maybe dcraw and exiftool updated...
#2
There are also a new version from a1ex, the build 22.

https://builds.magiclantern.fm/jenkins/view/Other%20tasks/job/cr2hdr-20bit/

Already tested and it's OK

All ok here!!

Thanks

I've been struggling to get a Windows binary of cr2hdr 20-bit version with the ml_dng changes applied. I do have a version built in the Cygwin environment which means you will need to download the .dll files for it to work. If anyone is interested in trying it out--here is the link.

I put the dll on the same paste that cr2hdr, and it gives an error (translated from portuguese -> entering point not found (dynamic library)

One question, why is the file half the size (in KB) compared with the a1ex original 20-bit version (186KB vs 366KB)

It could be missing things?

dmilligan just merged his code with the 20-bit version. I'm not able to open the Windows executable on my old laptop but for anyone who wants to do some testing--

Windows cr2hdr-20bit      Macintosh cr2hdr-20bit

It's a 16-bit app not compatible with my 64-bits machine...

Thanks. Here's the whole bunch, cr2hdr, raw2dng and mlv_dump.

These are working on my old Windows laptop and they should also work on a new 64-bit system. (Used mingw-w64-i686)


Already tested and it's ok, except it's not the latest 20-bit version, but cr2hdr 16-bit and the camera white balance isn't correct, maybe because it doesn't have the option  --wb=graymax

See the following picture, in the left is the cr2hdr 20 bit version, with tag corrected and in the right the DNG from this cr2hdr version

RAWTHERAPEE 4.2.276 with no processing with white balance set to camera. When in AUTO mode both looks equal



Also from the logs:

Anyone out there able to compile for Windows?
I'm also interested!!  :)

For starters try to delete tag CalibrationIlluminant2:
Open command line/terminal in directory where Exiftool and test DNG are located and run
Exiftool -CalibrationIlluminant2= <name of your file>.DNG

Report results. Don't use originals but copies, please!

Just tested and now it looks good on rawtherapee

Can this be corrected on cr2hdr? or i have to use exiftool for all files if i want to use rawtherapee?

@toze3:
Latest cr2hdr from here: https://builds.magiclantern.fm/jenkins/view/Other%20tasks/job/cr2hdr-20bit/ right?

YES

Do upload: Sample CR2 and Ouputed DNG.
I don't have the same CR2 was the DNG posted but i can upload a new ones.
CR2: https://www.dropbox.com/s/1p3tbx44vl9msgg/_MG_2498.CR2?dl=0
DNG: https://www.dropbox.com/s/83yju7334ibj19m/_MG_2498_DI100_800.DNG?dl=0
It happens in all my dual iso DNG.

Hope this helps

Workaround: Use exiftool to create tag Colormatrix2 and copy Colormatrix1 value into.


How do i do that?
#10
I was geting some troubles processing dual iso DNG in the latest version of Rawtherapee, i tought it was a white level problem and asked some help in their forum.

It seens there are some double tags in the dual iso DNG and missing color matrix?(not sure if only mine, with latest ML nightly on 550D and latest cr2hdr)

"your dng file includes both tags with the same value (21). In this case the second one (50779) is given precedence, but there is no valid color matrix for second one. Only the matrix for 50771 exists in your dng.
I try to catch this case in rt source, but you should also report the bug to the guys who made the hack to produce the dual iso dng files.
"

@a1lex could you have a look in this post

or make the normal aperture scroll wheel adjust the fstop number as if a auto lens was on. obviously it would actually control it but it would be faster to set up. but that leaves it up to you to remember to do it. I you forget to you data will be off.
Yes, it's that what i was thinking, but it can't be done now, because the value is always F00, and its impossible to change, that's the reason we are asking for some feature/option to do that.

maybe it can be don was a module to override settings, i don't know...

I just know this could be a great feature for people that use manual lens, better than writing or remeber the values.

Hi @a1ex

So many updates, but i have a question, should i use just the last one (now the cr2hdr-histmach2) assuming this one have alll the abilities of the previous versions or all are diferente and for diferent problems ?

Thanks for the excelent work
#13
Bump  :)

Already tought about this feature, if it possible it will bring for the manual lens users a excellent tool to record in the exif file the main data.

Maybe a simple menu (MANUAL LENS in the SHOOT TAB) that you can put the focal leght and the minimum/maximum aperture
Than you will have to say/sync/override into the camera the real aperture of the lens, using the dial.
It's better than have a F00 value, and maybe in the future this could help the camera to achieve better results (here i don't know??)

Is this possible??
