I am a die-hard Aperture user, but find high ISO RAW processing very frustrating for flesh tones. RAW has a strong red/magenta cast which is totally absent in jpegs - and VERY hard to eliminate. It helps to turn 'Hue Boost' to zero, but even so, the result is unacceptable. I offer a case in point - Peter Yarrow at a concert last night... Jpeg OOC: RAW: I have tried adjusting using Curves - very labor intensive, and the jpeg wins based on color, sometimes offset by DR or other factors. I have a trial copy of LR - no such problems. Nor is there a real issue at lower ISOs in Aperture. The Aperture RAW engine for the E-M5 is simply not good at high ISO - and it lacks the RAW controls to make it right. Anyone have any insights? Suggestions?
