Thanks all for the nice comments
@tclausen:
What you are saying about the cat is interesting and at the time I postproduced the raw file (from my K5, yes) I only had the Pentax software (and very very limited skills). I had to make a choice between texture in the cat's fur and an overall contrasty and eye-flattering scene. I chose the latter.
I have acquired DXO optics pro since then and this allows me for more refined PP operations even though I have been quite happy with the Pentax software.
In the case of this particular picture, I am now able to increase contrast and tones without transforming the cat into a just a silhouette.
Maybe this one is better?
