One could say it could not get any easier by selecting the most basic feature of photography, light entering through a lense and being digitized by any kind of sensor as topic.
On the other hand, photos like fellfroschs dice with cool shadow play, nh1402s fully lighted postcard or Macros nightscene towers could be compared on a level not restricted by the subject of the picture but the photographers skill to present it.

Wish you all a steady hand for Mays theme: Lighting
