Two pictures exhibiting extremely high dynamic range were used to compare the RAW converters. The Bibble sharpening was set to "100" during the rendering of the Blue and Gold Macaw; this setting resulted in unacceptable levels of shadow noise. Bibble sharpening was reduced during the rendering of the Australian Black Swan to a level that didn't blow up the shadow noise; unfortunately this setting didn't produce a very sharp image (compared to RSP).
