Sometimes I take a photo instantly...

... and move on without another thought.

Then I get it home, like today, and start to ask myself questions.

This started out as a reflection in a shop window. I tried hard to get the symmetry of the scene right but the side window, on my left, was in the way.

What I should have done is take another shot looking towards my original camera position so that I could answer questions like:

- was there more than one bike? or a spare wheel?

Anyone too young to understand responses mentioning Harry Worth, should google 'Harry Worth window trick'.
