Alright, so there's a variety of settings for the JPEG processing on Olympus cameras and I'm not quite sure what settings people tend to use most of the time. On the EM5 we've got seven picture modes: 1) i-Enhance 2) Vivid 3) Natural 4) Muted 5) Portrait 6) Monotone 7) Custom -- assigns presets from 1-6 To be quite honest, I'm not too clear on what some of these do. I believe 3-Natural is the default on the EM5, and i-Enhance was the default on older cameras. i-Enhance disables 120fps refresh for some reason, and I'm unclear if it behaves separately from the others or just tries to select one. Vivid, Muted, and Monotone are fairly obvious. It seems like Natural is supposed to be halfway between Vivid and Muted, and i-Enhance sounds like it's not a separate setting so much as it just selects between 2-5. Portrait is described as "Produces beautiful skin tones", which is pretty vague to me. I've heard that Muted produces results more similar to Panasonic rendition and closest to accurate. LR's defaults are noticeably less saturated than Muted -- though on my arbitrary test scene, I'd have to give the accuracy nod to Muted over LR. Of course I haven't calibrated this monitor since a Win8 install so I'm not sure about that one. There are also four Gradation settings: Auto, Low, Normal, High. I gather that this is a dynamic range optimizer like most manufacturers offer (i.Dynamic, Active D Lighting, DRO, etc). Basically it tries to lift the shadows, at the cost of noise in the lifted areas. Normal seems like a fair choice to me in most cases; Low leaves too many crushed black areas. What are you guys using for your picture modes? I've been going back and forth between i-Enhance and Natural, but I'm not really sure which one to settle with.
