And don't forget: the next "Worldwide Pinhole Photography Day" is on Sunday April 28th, 2013.
See: http://www.pinholeday.org/
Anyone anywhere in the world who makes a pinhole image on that day can participate by uploading his image afterwards (no costs).
And check the site for a pinhole workshop or gathering in your area.
So dig out your pinhole camera and start shooting again ;-)
