Slightly OT raw converter discussion

Good, snappy answer, but no prize.

The WB from the K-5 is usually spot on in this kind of shot (grey skies), so no adjustment needed. Also, if you look at the two images I posted (and what I wrote), you will see that Irfanview has done more than up the contrast. There is also an obvious increase in saturation, an apparent increase in clarity, some sharpening, and then there is something else that I can't put my finger on and can't replicate in Lightroom, and which is therefore what I am really asking about.

But thanks anyway.
