Luminance HDR: An Open Source Software for LDR/HDR Imaging in Ubuntu

Luminance HDR is an open source application based on Qt5 toolkit for LDR/HDR image processing. It’s a complete workflow for high-quality imaging including HDR and LDR formats. Luminance HDR offers a simple to use and intuitive graphical user interface. It’s a cross-platform application which supports Windows OS, Mac OS, and Linux system.

As I mentioned above that this software supports a wide range of HDR and LDR formats out of the box. Worth mentioning HDR formats are radiance RGBE, tiff formats, openEXR, PFS native format, raw image formats, etc. JPEG, PNG, PPM, PBM, TIFF, FITS all those are mentionable LDR formats, it does supports.

Like any other image editing software, it can also crop, resize, rotate HDR images and use projective transformations. With the help of the tools, a set of HDR images can be created and tone mapped smoothly. Moreover, you can copy EXIF data to or from a set of images easily.

Now, I believe you have a clear idea about what this image processing software does. so, let’s have a look at how to install Luminance HDR in Ubuntu Linux.

How To Install Luminance HDR in Ubuntu Linux

There are a number of ways to install this application in Ubuntu. You can use the unofficial PPA or flatpak on FlatHub. Here I am going to describe both the ways.

1. Unofficial PPA

Open the Terminal via searching Terminal in app menu or Ctrl+Alt+T and run the following command:

sudo add-apt-repository ppa:dhor/myway sudo apt install luminance-hdr
  • Remove the software if needed
sudo apt remove --auto-remove luminance-hdr

2. Flatpak Package

Before running the flatpak command, you must know how to enable flatpak repository in your latest Ubuntu system.

flatpak install flathub net.sourceforge.qtpfsgui.LuminanceHDRflatpak run net.sourceforge.qtpfsgui.LuminanceHDR

I have come to the last of my short review/tutorial. I hope it will come to your help while installing Luminance HDR in Linux. If you like this post, please share it on your social media. And don’t forget to give your suggestion in the comment below.

State of HDR on Linux early 2021 (previously late 2020)

Hey Guys! - Creating this thread to serve as an easily indexable search engine thread; as of now it’s a huge pain to determine the state of HDR.

Rather simple question: as of October 2020, what is the state of HDR support, in all of its flavours, on various distributions and on various hardware?

I’ll be updating this thread to included information from the comments below. If the configuration is not mentioned- it’s either not supported or support is unknown. I’m hopping to keep this updated as more information comes in.

in terms of other information, all 3 manufacturers have discussed HDR support to a certain extent.

Kernel 5.3 added HDR metadata to the amdgpu driver

Kernel 5.12 implemented near complete support for intel Gen9 HDR, but testing will have to be done once the 5.12 cycle completes

Nvidia seems to have some OS level support on kernel 5.8+ on their jetson series of SOM’s and SOC’s, but this has yet to be confirmed
Known supported platforms:
Known temperamental platforms:

Known experimental platforms:
[Intel gen 9]

How to Install Luminance HDR via Ubuntu PPA:

The Dariusz Duma’s PPA was maintaining the software package. It however seems not being updated except for auto-build packages.

For those sticking to an Ubuntu PPA, there’s an alternative unofficial PPA available and you can run following steps one by one to get it in your Ubuntu.

1.) Open terminal from system application menu and run command to add the PPA:

sudo add-apt-repository ppa:ubuntuhandbook1/apps

2.) Then install the HDR creator via command:

sudo apt install luminance-hdr


To remove the software package, simply run command:

sudo apt remove --autoremove luminance-hdr

And to remove the Ubuntu PPA, open Software & Updates navigate to Other Software tab and remove the relevant line.
