Just joined the forum today. Picked up an E-M5 a few weeks ago and am having a blast getting to know the camera. Only using it with the kit 12-50 so far. A long time in the past I did work for a couple years as a photojournalist, and then did some freelance work after that. Once I totally left the business I realized I would never really carry my whole SLR kit, and after a couple years of gathering dust I sold it off. Carried an advanced P&S for a couple years, but this year finally saw a camera that was small enough to carry hiking and skiing, and excited me - the EM-5. So for the first time I'm experimenting with raw, using the raw & jpg setting. I did some reading so I understood what - in general terms - the camera is doing to create the jpg (obviously it's different for different settings). So at this point, still a newb to shooting raw, I'd like to get a better understanding of what processing the camera is doing to create a jpg, and if it could be exactly duplicated in Aperture (which I have just started learning)? I'm curious, because some types of photos - low light portraits for example - look way worse in raw form than in the jpg. The raw looks grainer (noise?), the skin tones are more reddish and less even. So for a plain vanilla setup, what is the E-M5 doing in terms of processing to create a jpg?
