Having a quick look through their blog, most of the photos are superb. A little sharpening here and there but I am pretty sure that there is a minimal amount of post going on (especially with regards to contrast).
Very well lit and composed photographs. LF photos are IMO some of the best out there.
It's very difficult to get a photograph which looks that good straight out of the camera. A lot of time would have been spent getting the lighting and composition absolutely spot-on.
