I was waiting for my tour group to gather after a tour of the Roman Colosseum. As always, the ancient building was crowded, noisy and swelteringly hot. I turned away from our group and found these two tourists sitting in the flood of light entering the colonnade, no doubt plotting their strategy for their visit to Rome. This photo makes the Colosseum look quiet, cool and relaxing. Maybe that's the magic of photography. Or may it's the deception.

There are many things I like about this photo: I like the repeating lines of the columns and the repeating bright and dark made by the Roman sunlight. I also like the pock marks that show the age of this place. Finally, I like that by accident the three primary colors are present in this photo, though in very muted shades. Can you see them?
