Here are some GH3 RAW photos being processed with the Generic Fuji Astia 100 (from DxO FilmPack)
All photos were taken with the Voigtlander 17.5mm f/0.95 lens.
Top is original, bottom is processed. No other edits were done.
Generic Fuji Astia 100 adds slight saturation and a bit more contrast. It's difficult to tell from the 640 pixel wide photos below. Try saving them (right-click save as) to compare them on your computer.
The DxO FilmPack has a lot more fun presets to try. I think they give the rather generic (in my opinion) GH3 raw file a less digital look. I was never quite happy with the GH3 files, which is why I bought the Fujifilm X-Pro1.
