Is there a place where newer Windows builds can be found?

I suspected as much. I suck at building apps for Windows, so I guess I will have to wait. :timer_clock:

hello all! Back from travel.
Let me a few days to build a new version of HDRmerge.


No worry, I hope you enjoyed your travel.

Was it for pleasure or business (or maybe a combination :-S) ?

I travelled with friends during one month in the north of Madagascar. Very interesting but also tiring due to the roads and tracks conditions. Powerty is increasing compared to our last travel 3 years ago.



Madagascar sounds nice. I hope you got good pictures there :smile:


When I open this the about page shows V. 0.5.0 Which happens to be identical to what is shown when I open my already installed version downloaded and installed around a year ago from here:

Are they identical, as the “about” window leads me to believe, or are there actually changes and the “about” info just not updated yet?

I haven’t checked in a while but last time it wasn’t the same. There have also been some commits on a branch and I don’t know whether they have been integrated.

For nightly builds, the only meaningfull information about configuration is provided by the file name, for instance:

Branch: master
tag: continous
64: 64 commits form tag
g1408e42: 1408e42 hash from last commit
release: release build
64: 64 bit windows

The about window informations are not automatically updated with git configuration informations as it is done in Rawtherapee. Same for window title.

As far as I know, cacorrect branch is not merged into master branch.
Thoses branches include last commits.

Would be lovely to have another recent Windows build. There are several known issues which may be fixed in the meantime (e.g. the broken JPEG preview in the DNG due to upgrading Qt from v4 to v5).

It’s the last version I found.
Edited, thanks @LigH-de

Almost: (“Merge” was missing in the URL)

Thank you!

PS: Unfortunately, this build does not yet contain the fix for the broken JPEG preview in the DNG. The output seems to be identical with continuous-64.

I will recheck in the HDRmerge repo if I find newer commit, but I doubt.

have you a link describing the fix or the issue?

This one?

SHA-1: 6c892cbb3ae2f7176d72ab3ee7cab42d711285ec

  • Fix wrong format “JPEG” for writing the preview.

@LigH-de Are you sure you downloaded the build identified just above?

@heckflosse If it is a v0.6 version, why it is identified v0.5 in the window banner? If it is a stable version, could it be tagged 0.6 or if you prefer v0.6?

I am really sure, yes.

HDRMerge_master_continuous-64-g1408e42_release_64\hdrmerge.exe (2019-07-25, does not contain the string “JPG”) => DSCF4758-4758.dng (13056040 bytes, does not contain the string “JFIF”)

HDRMerge_release-v0.6_continuous-71-gd7d8041_release_64\hdrmerge.exe (2020-02-24, contains the string “JPG” once) => DSCF4758-4758.dng (13056040 bytes, does not contain the string “JFIF”)

Seems the patch is not the fix?

That seems so!
Then could you open a bug report at

For help writing it, see

I will possibly rather ask to reopen the already existing issue.

@gaaned92 the imageformat plugins are missing in the zip.
An for jpeg support the jpeg plugin (libqjpeg) is needed.

For Windows, this will be a qjpeg.dll like in Luminance HDR.

I copied that DLL over to a subdirectory imageformats below the HDRMerge installation, and it created a DNG file containing a JPEG preview. You will prefer to deploy a current version from your QT 5 installation for future releases.
