Diptychs

A diptych is a pair of photos that somehow tell a larger story by the contrasts between the juxtaposed images.  Good ones are hard to find.

In this one, a Magnifying glass inverts images at different focal lengths.

Here's a webgroup page that diptychs are uploaded to every day.

Bud and flower.
A pun - a sign and its reflection.
in this one, the bottom image is everything from his pockets, I think...
and in this one, I like the comparison of the arrow and the interior angles of the building.
It can make for a nice portrait pair.


Particularly interesting are so-called 'natural diptychs,' where something in the image naturally splits it in two.
There's a blog that discusses these.

I like the following one because it contrasts the entry-level job of the waitress, looking longingly out at the genteel sophisticated diners. There's a little tension and anticipation in her pose.

This one looks at first like a reflection, but the difference in times shows it's two clocks mounted on the same tower.

I really like this one, because you think it's a solid building on the right, until you realize the same tree is visible through it, and you can make out the staircase and opposite window in the building.   

This one takes a moment to figure out...at first it seems the shadow is of the parapet in the foreground.

Here's one of a boy and his view of the sky.

Two photos, same person and location, 50 years apart.
