The New LR 4.1 RC2 Defringe tool
As mentioned previously, the new Release Candidate of Lightroom 4.1 has introduced a new Chromatic Aberration reduction feature. At first sight it seems quite a complex tool as it has double handles on a slider, which is a Lightroom first! But this new feature is very powerful.
Lightroom 4.0 and Lightroom 4.1 RC2
The Local Adjustment and Gradient tools now include the new functionality as well.
The new controls are mainly found in the Lens Correction panel in the new ‘Color’ section.
A comprehensive description of how this all works has been posted by Eric Chan who is one of the Camera Raw engineers on the Lightroom Journal blog and it is well worth a read. The examples given show just how good this tool is.
