Certainly one of the most interesting upcoming technologies for photographers is High Dynamic Range Imaging (HDRI), allowing work with the full real world levels of illumination. While standard image formats utilizes 8 or 16 bits with applied gamma and color space, the HDR image format extends the bit depth up to 96bit in a linear color space.

On this overview we will focus on the currently available Windows GUI-based software packages that are able to create and process HDR images. I want to thank all authors of the respective software packages for their support during the creation of the overview, especially Geraldine Joffre, Andreas Schömann, Paul Nolan, and Thomas Lock. Aside from the windows based GUI packages Bernhard Vogl has evaluated, command line tools are also available and have been added to the table below.

The following software packages have been tested:

As you can see,there is a wide variety of fees you have to pay for the different software packages. This is partly justified by the features and the editing functions the various programs offer.

*1: Most software relies on DCRaw for RAW conversion. Some cameras with extended DR capabilities are not converted correctly (e.g. Fuji's S3 camera: Although DCRaw could theoretically read all photosensors, it would need one conversion call for every photosite which is not implemented in the tested software packages.)

HDR image manipulation

There are basically 3 types of appications available:

  • Converter software: This type of software will assist you in generating and tonemapping HDR images
  • Image editors: These are full-flagged image manipulation programs that will also give you the possibility of HDR generation and tonemapping
  • Panorama creation programs with the additional possibility of HDR generation and tonemapping

*1: TIFF: 32 bit floating point TIFF. Please note that the TIFF file format is an abstract container for various encoding methods. This may result in incompatibility when exchanging TIFF files between various applications.
This is also true to some extent for .hdr files. Though, all applications in this overview use the most recent file format.

UI functionality and large image processing

The best HDR software is not of much use if it lacks of an intuitive user interface. We will now have a look on some key functionality and UI design.
We will also have a look if the applications utilize a clever memory management. The test file is a HDR panorama stitched by Hugin with a size of 8000x4000 pixels (32 Mpix), converted to the Radiance (.hdr) format. (This is tested using a standard Windows XP setup w. 1GB of RAM, swapping to HDD allowed)
