Originally posted by oculus does the proximity take the subjects out of their environment?
I think that's a nice insight, but I don't think it's a matter necessarily of "how close" as to
where the subjects are in the frame. For instance, the "security detail" that struck my whimsy is anchored on the left side by the dapper gent that's quite close to the lens, but the rest of the frame is occupied by interesting human figures in the middle distance(s). Similarly, the picture of the old woman in the Chinese market is a similarly articulated moment in time, with her figure almost tumbling out of the lower half of the picture, as if from a panel of a manga. The difference with these images, though, is that they follow the "rules" for composing half-torso portraits--you can't see the forest for the tree planted four-square in the frame. To my mind, there's a lot more energy to be found in those idiosyncratic compositions from your earlier photos.
As for WB, I also think you're at a disadvantage when "It's Always Sunny in Philadelphia" when shooting color, simply because the default values SOOC provide results indistinguishable from the typical, casual "snap." You might agree with Dartmouth Dave that monochrome is (finally) played, but for myself I could see the need to establish some genre conventions, a "sign" as it were to use to read your intentions as an artist and your relationship with the subject. (Unless you're doing the greasy Terry Richardson thing, and there it helps--a lot--to have your camera pointed at Kate Upton.) One thing you might consider is desaturating things a bit and cooling the WB--a kind of Voigtlander preset, as it were.
