HDR Software overview. 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 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: Software overview As you can see,there is a wide variety of fees you have to pay for the different software packages. See Also.

Un excellent logiciel, pour toutes plateformes. Anyhere Software. High Dynamic Range (HDR), exposure blending and tone mapping sof. High Dynamic Range image processing tutorial with easyHDR PRO - If the input photos are misaligned in respect to each other you may take advantage of the automatic, or manual alignment. Both are capable of compensating for shift, rotation as well as perspective misalignments.
The manual tool may be used in a semi-automatic way. Just use the automatic pin placement option, then you can verify the quality of alignment and do corrections (should they be needed). The idea of manual alignment is simple - just select the base photo and place the pin pairs (each pair is marked with a different color) in a way that they point exactly the same details on the base picture (top left) as well as on the photo to be aligned to it (top right). The live preview is shown in the lower left window, but please note that all the pins must be placed before the good preview is shown.
In the majority of cases however, automatic alignment is sufficient. Tip: You can save the aligned photos to files. Sample HDR tone mapped images created with easyHDR. Sunset over the Arno river in Florence - view from Ponte Santa Trinita. Three photos were taken without a tripod, so they must have been aligned with easyHDR manual alignment tool before being merged together. True-HDR method with "Normal" selectivity was used to generate the HDR image, that was later tone mapped. The tone mapping settings were just slightly modified in respect to the defaults.
The "compression" was slightly increased to make the photo a bit brighter, without loosing color saturation. Also the "Local contrast strength" was increased a bit to make the photo look more dramatic. © Bartłomiej Okonek.
