HDRsoft (http://www.hdrsoft.com) has released Photomatix Light, a
stand-alone HDR (high dynamic range) photo processing application for
Mac OS X 10.5 and higher.
Based on the same internal HDR processing engines as Photomatix Pro,
Photomatix Light merges bracketed photos and processes them with HDR
tone mapping or exposure fusion methods. After selecting the source
photos, users can adjust the processed image by changing various
settings, or choose from built-in presets such as Painterly or Grunge.
Photomatix Light automatically aligns bracketed exposures, allowing
hand-held photographs to be used as well as tripod-mounted shots. One
license of Photomatix Light costs US$39. It’s free for licensed users
of Photomatix Pro.
