EasyHDR PRO is image processing software that produces and tone maps High Dynamic Range (HDR) images out of photo sequences taken with a digital camera. It is capable of importing several image formats: JPEG, 24/48-bit TIFF and any RAW photo (thanks to integration with DCRAW program). EasyHDR PRO can also import Radiance RGBE (*.hdr) or 96-bit TIFF HDR images that were previously generated with any other HDR image processing software. In order to produce a well exposed and dramatic-looking photo it is not always necessary to use a series of differently exposed images. Sometimes just one photo is sufficient. That's why easyHDR PRO gives you the ability to process a single image - the feature is called LDR (Low Dynamic Range) enhancement. High Dynamic Range image covers much wider dynamic range (light to dark ratio) than a normal digital camera can record (due to noise and overexposure). A HDR image is created by blending an image sequence of photos taken at different exposure values (various shutter speed, ISO sensitivity or aperture). Each photo in the sequence shall cover a part of the dynamic range of the photographed scene. The resulting HDR image will therefore contain the full information from all of the photos. In many cases the photographed scenes do not characterize with very wide dynamic range, so taking an image sequence in order to assemeble and tone map a HDR may be too much effort. Also, by taking a RAW photo, instead of JPEG you can achieve a slightly higher dynamic range, so a single photo may be sufficient.
