Story behind the photograph
A simple mirror image photograph of a girl standing right next to a shop window. Sharp angle of view and the fact the girl was right on the edge of the window provided for a very clear reflection.
Now, let me explain what is wrong with it. If you put the camera to your eye and use the optical viewfinder or even the in-build electronic viewfinder your camera is relatively steady as it rests against you. If you move a little bit it probably won’t even matter and the photograph will be sharp. When you stretch your hand out and move by the same factor the length of the arm multiplies that movement resulting in blurry images.
