Photomatix is a program that will extend the dynamic range of digital photographs or scanned films.
If you have ever shot a high contrast scene, you probably know the problem blown out highlights and loss of contrast in shadows.
Photomatix offers two ways to solve this problem:
■ Exposure Blending: Merge differently exposed photographs into one image with increased dynamic range.
■ Tone Mapping: Reveal highlights and shadows details in an HDR image created from multiple exposures. The tone mapped image is ready for printing while showing the complete dynamic range captured.
