"What kind of post processing are you applying Thomas?"
Pierre, with landscape shots I typically dont do much.
I shoot RAW, so I pull it into photoshop RAW and adjust the sharpening a bit.
Usually use the slider up to 50, and back off the pixels to .5
I will then adjust the mid range contrast up to 25 or 30, make sure that any blown out areas (if any) are addressed. Then, once in working view, I will employ the LEVELS function with a new layer and just hit AUTO. If it looks good I keep it, or if it needs adjusting I can back off the opacity if necessary, or I can also just scrap the new layer and keep the original. My goal is to try and capture the scene as I found it, but we all know that's not always possible.
