Photomatix 2.0
is an application that extends the dynamic range of digital photographs or scanned films. It accomplishes this through the use of exposure blending -- combining overexposed and underexposed versions of the same image to blend them into one -- and tone mapping, which takes a High Dynamic Range image and processes it to compress its tonal range while preserving local contrast. Photomatix 2.0 is $100; a free trial is available.
