Happy World Pinhole Day!

For the past five years, people have been invited to take one pinhole photograph and submit it to the World Pinhole Day gallery. Pinhole cameras just use a pinhole to let light through. They have no lens and no viewfinder, no meter and no moving parts. Most people put unexposed paper at the back of a box, but you can also use film if your camera allows this. Last year saw 1800 entries to World Pinhole Day. Here's mine (I'm number 193!), taken on a stretch of road at Westminster.
