Hey bro, I like your images' sharpness and colors very much, mind sharing some post-processing techniques? ;p
Thanks. They are pretty standard.
Portrait setting
The places shots done using in-camera HDR2.
In PP :
Standard shots
Levels > Curves (very slight) > resize > sharpen
Usually no saturation added as Pentax colors are very saturated as they are.
HDR shots
Levels > Curves (tweak the dark tones to make them look right; highlights need very little) > saturate (very slight if necessary) > resize > sharpen
Hope that helps.
