There’s so much I admire about this shot. First, it’s well spotted and composed. Initially, I thought it might be posed, even, but there’s really no indication that is the case.
Secondly, pablo.raw certainly threw his camera into manual. With oncoming lights and the relative darkness of most Metro stations, it’d be all but impossible for the exposure and focus to have hit the right spot.
Lastly, Metro stations make great backdrops, and it’s still not illegal to take great looking pictures in the system!
