I'm sure everyone has seen this mentioned on other sites, but seeing as there's a pinhole forum here, that someone should post a link: http://www.pinholeday.org/
Saturday 25th April is "World Pinhole Day". Go out and take a picture on that day, using any kind of "non-lensed" camera (ie zone-plate=good!), and submit it to the pinholeday site.
I've only done a few pinholes, but I've stocked up on grade 1 paper, and my card index box camera is ready to go...
Whats everyone got planned?
(this is nothing to do with me - just passing on the link).
