Ok : the picture has been shot RAW, ed of the day golden hour, exposed to the right. Then processed in Lightroom, here is my worflow :
0) Reset to zero every slider in LR
1) Adjust WB : warm tones was needed and color correction : in the idea of using an old time velvia :
Blue Luminosity -30 , and Orange Luminosity +30
2) Boost exposure until the first RED saturated piwels appear, without taking care of the sky (after this the sky is overexposed).
3) Boost the black slider until first BLUE pixel appear.
Now white and black point are defined.
4) Apply a graduated filter for the sky : bring down the exposure and luminosity to dramatize the sky, boost contrast and clarity
4) Ajust Luminosity and Contrast as needed (the less lluminosity the more color will naturaly saturate)
5) Add Vibrance and Clarity
Take a coffe,
and check if it's not too much !!!
That is my general landscape workflow with LR3.
Hope it helps and sorry if you spot mistakes in my english...
