Daniel, that truly is a good post processing. I really like that image. I like shooting markets, but haven't lately. I'll see if I can find some of my old DSC-P31 pics of markets and produce I have and "tweak" them ;)
Thanks to you all for commenting. No, Nugar, no special settings and no special lights: available natural light only; Naschmarkt is an open-air food market and I shot this picture on a september morning at nearly noon ... not a good time of the day for photography, generally. But, yes, when postprocessing I did work a little on the hue after applying levels and I did increase saturation quite a bit. db.
