Review: HDR on Linux with Qtpfsgui
Editing HDR images on Linux is not so easy: the current situation of HDR image editing on Linux is so so. Especially tone mapping is possible, but not easy: the libraries are available, but there was no GUI, let alone an easy to use and user friendly GUI
But today I came across Qtpfsgui (kde-apps entry)- and I was impressed. The GUI is slick and the handling is easy. It provides you with all options needed for the task, and even does not have complicated dependencies. Technically, the Qt4 program includes (which means there is no dependency) code from the famous projects PFStools and PFStmo.
Ok, Qtpfsgui does have a naming problem, but that’s the only flaw. But I can take such a name when I get such a GUI:

LWN Grumpy Editor's guide to HDR with Linux
The idea behind HDR, as it is used with photography, is to extend the available dynamic range by taking multiple shots at different exposure levels. For a given exposure, there will be a range of light levels which will be captured with good resolution by the sensor; everything else gets compressed at one end or the other.
The first HDR-generation tool to look at is cinepaint, once known as "Film Gimp." This tool is a fork of the GIMP which is aimed at use by movie studios; its floating-point image data support makes it useful for HDR processing as well. The generation of HDR is done with the "bracketing to HDR" plugin which is, happily, packaged with the cinepaint source distribution.
