The History of Solargraphy
Solarigrafia is an original idea by three people: Slawomir Decyk, Pawel Kula and myself 13 years ago and we are still involved over global solargraphy projects, (notice"solargraphy" is the english translation from the invented spanish/polish word "solarigrafia"). You will find lots of information about solargraphy and many original projects related in our sites. Also in the Time in a Can Solargraphy Project website.
Here you have a link to Alternative Photography website, with an old but interesting interview to Tarja Trygg: http://www.alternativephotography.com/wp/processes/pinholes/solargraphy-catching-the-suns-path-pinhole-camera
