Olympus jpegs do magic moire correction

ACR doesn't use the best demosaicing algorithm for avoiding moiree. besides in order to avoid green-imbalance artefacts during demosaicing a higher degree of green equilibration is used for olympus and panasonic cameras which increases moiree even more.

AMaZE from raw therapee deals quite well with moiree, although it cannot avoid it completely either, besides it is able to pull out even more details out of the RAWs than ACR.
