Some of the colours I get from this combination (OM-D + 60 f2.8 macro) seem rather blown but in fact they are not. Saturation seems to have been pushed to the limit, but again the saturation slider wasn't implemented. These have just been put through LR 4.4 without much being done to them at all. As some of you may now know I'm a raw only shooter so the jpg engine in the camera didn't come into play with any of these images.
It is rare that I increase saturation in LR, it really does increase what I don't want saturated. I'll use clarity and the vibrance sliders. Vibrance increases the subtle tones and colours and that is the look that I go for in my images, or try to anyway.
