Fantastic shots. I think a big part of these pictures (and a big part of what I'm missing in my own photography) is a clarity in vision, and an understand of post production. Some of saturation they're getting in those pictures is not native to the camera, and then of course, the crop, border, treatment and effects. But it's not post production for pp's sake. It's all related to their vision.
I begin to think the biggest issue that sets someone like me (technically adept, and capable of reasonably good composition) apart from a pro like these folks is their clarity of vision and what they want to achieve -- from being at the scene, to the moment it clicks, to post production -- it all shows a clear vision, and perhaps even one preconceived before the pictures. I've been thinking a lot about that lately. I usually wander about, and take pictures of whatever's in front of me, and I have 8 lens choices (6 primes and 2 zooms). No clarity of vision, and no idea what to achieve. These folks make these marvelous pics with a (presumably) fixed focs lens and tiny sensor. I love seeing work like this, and really see a pro who is achieving what they set out to do.
Thanks for sharing!
