Alf I see more shadow detail in the jpeg its also slightly more contrasty
Both are good the LR3 seems more natural if slightly muted
Look on the jpeg image
The RH steel columns the climber
The Bush between the 2 LH columns is brighter
Using the Oly RAW convertor would produce a result near Identical to the (natural setting) camera jpeg
I have found the manufacturers RAW convertors Oly or Pany less ambiguous
However the result that pleases YOU is important
