Post Processing HDR images – Tone mapped HDR images are rarely perfect when the HDR program finishes with them. They can look flat, lack overall contrast, and can suffer from artifacts, ghosting and halos. Ferrell McCollough of www.beforethecoffee.com explains how to correct such problems.
Many problems can be corrected in post processing using:
* Levels/Curves
* Simple cloning
* Blending of the tone mapped image with another image to restore realism.
1. Blend the RAW single image with the HDR image. You can blend the 0EV, -2EV or +2EV.
2. Tone map the RAW image and then blend with the HDR. A pseudo-HDR with the HDR image.
3. Blend two HDR’s each processed with a different tone map setting.
4. Blend an HDR image created with a local operator such as Details Enhancer (Photomatix) with an HDR image created with a global operator such as Tone Compressor (Photomatix).
