This is just a classic Leica photograph. Know a breakdown of the composition.
Leica M6 with 50mm 2.0
Simple composition made up of circles and squares. Street photographers have been taking photographs like this for a 100 years. Film used was Ilford Delta 400 and I processed it myself. The composition is basic rules of thirds. Placement of door knob and lock are lined up on the thirds and the window on the upper right and the square on the lower right balance with the door knob and keyhole. I like the window shade raised just a little and the key lock that breaks up the all white image. Contrast increased a little to brighten the image.
