    Edge-artifacts when increasing clarity on Sony raws

    wronglyNeo

      I noticed some unpleasent artifacs on hard edges in many of my raws captured with Sony. They seem to appear as soon as the clarity value is raised.

       

      Here is an example:

      Note the artifacts at the vertical border between balck an white. Here is an enlarged version:

      Here is the same image with clarity set to 0:

      Everything is fine here. I've never encountered these artifacts with raws of other manufacturers, but I can not say for sure that they don't occur there as well.

       

      To me this looks like an erroneous or at least unexpected behaviour of the clarity algorithm. I have many images where I was able to make out similar artifacts. The raws are from a Sony A7II camera and are uncompressed ones. It would be nice, if this could be fixed.
