Lightroom 4.1 Defringe Tool

Have you downloaded Lightroom 4.1 yet?  If not, you're really missing out.  Check out this shot:

This was shot with a Tokina 10-17 fisheye.  I am working on a review of that lens but for now note that the Tokina fisheye is very susceptible to purple fringing and chromatic aberration:

Lightroom 4 includes a command to Remove Chromatic Aberration but Lightroom 4.1 takes this further and adds an additional tool for removing aberration: the Defringe tool.  It has an eyedropper and all you do is click on any purple or green fringe color.  Check this out:

Boom! Gone in just one click!

If you look closely there is a little bit of green fringing.  Just click the eyedropper a second time, this time on green fringing.

Now both purple and green fringing are gone.  Tokina should include a copy of LR 4.1 with every lens they sell! :)
