I just had a pow-wow with a couple of cool documentarian/photographers at "the studio", which I've decided to call it. You should really check out their webzine, the head graphic to which I stole and uploaded below.
It's a gathering of several photographers who do some serious shooting and photo work in the Seoul area, and document some places that have already disappeared from the Seoul landscape forever (like the rich and lively railroad track near my home here in Gongdeok, which I was happy to see he recorded for posterity with his camera.
