Its natural mode on OMD. I shoot RAW, ETTR, adjust highlights/whites/shadows/blacks/exposure/contrast. Just doing this will produce very "organic" images I have found and there is an amazing amount of detail that can be bought out of the images by carefully working with these slipers. I adjust in ACR (Adobe camera reader.. I think its called) and then I bring into Photoshop. I am going to move to Lightroom soon to do these steps though. In Photshop I add slight sharpening etc and then sometimes vignette..
