I just became a HDR convert. Holy cow. Let’s see what you think…
What a difference using a single RAW capture. Higher fidelity and more even exposure is typically achieved with 3-5 RAW shots spanning across exposure settings like (+2, +1, 0, -1, -2) or (+2, 0 , -2). Multiple exposure execution would have taken care of the blown highlights in the clouds, which were too far gone to compensate in Photomatix or Photoshop. Very impressive processing.
Photomatix is now on my recommend list.
