[Jun 20, 2006] Tarja Trygg uses pinhole cameras to document the normal changes in the path of the sun through a season. The goal of her project is to create pinhole solargraphs all over the wolrd and build a World Map of Solargraphs.

Tarja began photographing the sun as a part of her PhD studies in Helsinki, Finland. "I began my experiments in May, 2002 with short exposure times and as I continued to research this method my interest has grown bigger and bigger like a snow ball rolling forward. I wanted to have solargraphs even to a half year exposure time."

Tarja relies on 'can assistants' around the world to place cameras at various latitudes. "I tried to make a global map of solargraphs. But it is not possible to do this alone. Of course I liked the idea to get a sponsor who would finance me traveling all around the world for installing my pinhole cameras all over the world. After that I would travel again to pick them up. But, because I have no sponsors and no money I thought it would be better to ask volunteers 'can assistants' to help me.'

"I have not yet counted all the volunteers - my friends, relatives, colleagues, students, people I have met in conferences or any places I have asked if they want to do a favor for me. All can assistants are such lovely persons who think that solargraphs are amazing and the aesthetics of this kind of image. I am very
happy about each can assistant of this project."
