CS6 Camera raw 184.108.40.2068 : can't find manual defringe tool, only automatic by checking a box. The lens effect tool only offers custom and manual panel. No colors for manual defringing. ??
You should update your camera raw plugin to version 8.3
Help>Updates from within photoshop and apply any other updates offered as well.
Done & OK. Thx.
I don't think Defringe came in until 7.1.
