The City Daily Photo July theme is Transparent. This one is a challenge. What can we see through that we can still see in a photograph? As an example, I keep a crystal ball on my desk. The bottom has an inscription by the artist Jenny Holzer that says THE FUTURE IS STUPID. Underneath is a Chinese 10 yuan note I kept as a souvenir and, you know, just in case. What can our members see and see through? The Linky is open from June 25 to July 4.
