PhotomatixCL is a command-line program for HDR photo processing and designed to be integrated into automated imaging solutions.

PhotomatixCL takes a set of bracketed photos as input. It merges the photos to HDR with alignment and ghost removal options, processes them with tone mapping or exposure fusion, and saves the resulting tone mapped / fused image as JPEG or TIFF, along with the 32-bit merged HDR image file if desired.

PhotomatixCL is based on the same HDR styles and presets as the Photomatix Pro application. You can get a good idea of what PhotomatixCL can do by using the Batch Bracketed Photos tool of Photomatix Pro.

The commands for using PhotomatixCL are described in the PhotomatixCL Documentation.

PhotomatixCL runs on Windows and Linux.

The pricing for a PhotomatixCL license is detailed here.

or if you running on Ubuntu 14.04:

Download static version of PhotomatixCL for Ubuntu 14.04

Note that the statically linked version doesn't include lens correction.

Installation instructions


  1. Double-click on the file you downloaded and follow the instructions of the installation setup wizard.
  2. The PhotomatixCL.exe executable is installed into the folder you selected (by default C:\Program Files\PhotomatixCL).


  1. Go to the directory where you want PhotomatixCL to be installed, and run this command:

    tar xf FolderDownloadedFile/PhotomatixCL-6.0.tar.gz

    Where FolderDownloadedFile is the path to the folder where you downloaded PhotomatixCL.

  2. To get EXIF data copied to output files, install the "exiftool" package using your system's package manager.
  3. If you want to get automatic lens correction (for cameras and lenses that are supported), install the "lensfun" data package on your system. This is called different things on different systems, but try "lensfun", "liblensfun" or "liblensfun-data".
