it's actually hard to tell, every picture I treat in different way according to what I think I can take out of it. First some Tone Mapping stuff using RAW in Photomatix [I play the most with luminosity, light smoothing, color temperature, gamma, saturation for shadows & highlights and shadow clipping at the last step]. I'm just getting used to this software so it's more like experimental guessing for me yet. When the picture has good exposition - I open it with Paint Shop Pro [my beloved old version from about 2000, I work with it since four years and always use only this]. Now - some color correction, reducing noise [salt and pepper filter], clarify & contrast enhancement, saturation, sometimes highlights correction or additional light sources. And retouch, of course. But, as I said, it all depends on the picture. I don't have any presets or schema of work, it's always almost full improvisation.
