Building entrance hall

Walking on the street. Passed by a building door. Saw an old man walking in. Stopped. Took the iPhone from the pocket. Swiped open the camera. Framed the scene. Pressed the shutter button a couple of times. Started walking again.

Not a minute passed and this particular photo didn't came out that good, but I still find it amazing how quick and easy and with no preparation anyone can capture a scene nowadays.
