    Lens correction bug, bad artifacts with contrast adjustments...

    kwalsh74

      Something has changed between LR3 and LR4 in the processing chain for lens corrections.  Doing an extreme correction (e.g. using a LCP for a fisheye lens) with increased contrast causes bad halos at contrast edges.  The effect doesn't occur with the same settings on LR3.  It is almost as if the LCP is being applied after the basic controls rather than before?!?!?!?!
