Query – HDR Halo Removal

The following images of the Grand Canyon are high dynamic range (HDR) images. In editing these HDR shots the challenge has been to try and eliminate the halo surrounding edges of highly contrasted colours within images. The method experimented with this week has been to open the Develop module in Adobe Lightroom and within the Lens Correction menu to utilize the ‘Remove Chromatic Aberration’ there instead of relying only on a similar feature in the HDR Efex plug-in, on the plug-in side of merging the three (or more images). Beyond this, NiK Software’s Viveza is used to sharpen and add contrast and adjust/decrease brightness; after that Topaz Labs’ Clarity and Adjust helps adjust sharpness and saturation. With Viveza I’m finding success in editing toward what I want. I still am learning about choosing the filter/preset in Topaz Adjust and then finding optimal saturation from there.

If you are an HDR image creator I would appreciate hearing from you and the method you use to create your non-halo HDR images; this week, a software product called HDR Expose 3 (by Unified Color) has been recommended for its de-ghosting (halo elimination) capacity … do you use this?

Quote to Consider – “In the past, a discontent with reality expressed itself as a longing for another world. In modern society, a discontent with reality expresses itself forcefully and most hauntingly by the longing to reproduce this one.”
