HDRView
HDRView is a research-oriented image viewer for examining and comparing high-dynamic-range images: what the values actually are, which color space they are in, how two images differ, and what the file claims about itself in its metadata.
- Exposure, offset and gamma, false color over 17 colormaps, and zebra-striped clip warnings
- True HDR output on Wayland compositors that support color management
- ICC profiles, CICP code points, and gainmap HDR photos from recent phones
- Pixel inspector, per-channel histograms and statistics, and difference blending against a reference
- OpenEXR (multi-part and multi-layer), Radiance HDR, PFM, PNG, JPEG, Ultra HDR, JPEG XL, JPEG 2000, AVIF, WebP, TIFF, DDS, QOI, and camera raw
Compatibility: Uses the C library of the system (may need glibc 2.35 or later)

Usage
HDRView is available as an AppImage which means "one app = one file", which you can download and run on your Linux system while you don't need a package manager and nothing gets changed in your system. Awesome!
AppImages are single-file applications that run on most Linux distributions. Download an application, make it executable, and run! No need to install. No system libraries or system preferences are altered. Most AppImages run on recent versions of Arch Linux, CentOS, Debian, Fedora, openSUSE, Red Hat, Ubuntu, and other common desktop distributions.
This AppImage uses the C library of the system and may need glibc 2.35 or later. It does not run on distributions that use a different C library (such as musl on Alpine Linux) or an older glibc.
Running HDRView on Linux without installation
Unlike other applications, AppImages do not need to be installed before they can be used. However, they need to be marked as executable before they can be run. This is a Linux security feature.Beware! AppImages are usually not verified by others. Follow these instructions only if you trust the developer of the software. Use at your own risk!
Download the HDRView AppImage and make it executable using your file manager or by entering the following commands in a terminal:
chmod +x ./*.AppImageThen double-click the AppImage in the file manager to open it.
Sandboxing HDRView
If you want to restrict what HDRView can do on your system, you can run the AppImage in a sandbox like Firejail. This is entirely optional and currently needs to be configured by the user.
Updating HDRView
If you would like to update to a new version, simply download the new HDRView AppImage.
Integrating AppImages into the system
If you would like to have the executable bit set automatically, and would like to see HDRView and other AppImages integrated into the system (menus, icons, file type associations, etc.), then you may want to check the optional appimaged daemon.
Note for application authors
Thanks for distributing HDRView in the AppImage format for all common Linux distributions. Great! Here are some ideas on how to make it even better.
Pro Tips for further enhancing the HDRView AppImage
Please consider to add update information to the HDRView AppImage and ship a .zsync file so that it can be updated using AppImageUpdate. Tools like appimagetool and linuxdeployqt can do this for you easily.
Please consider making the HDRView AppImage self-contained, so that it does not depend on the C library of the system and runs on more distributions: ship the C library including its loader (ld-linux-*.so.*) and use it to launch the application, or link statically.
Thanks for shipping AppStream metainfo inside your AppImage. Please open a pull request on https://github.com/AppImage/appimage.github.io/blob/master/data/HDRView if you have changed it and would like to see this page updated accordingly.
