Don- Heres two links that you may find interesting
Solagraphy, Tarjda actually sent me some pinhole cameras for her project so I gave them to a friend who lives in the Faroes Islands who also placed some in Greenland. I dont know if they worked but the site gives you idea of what Im trying to acheive. Hopefully I can build a weatherproof version and get a 8 month photo of the sky.
Pinhole website
Heres a type of example of what Im trying with the leaves, Im starting small and the process they do is different, but the principle is the same. I got a few books out a few years ago and became facinated with different print mediums that dont involve film
using leaves as film
That website is pretty good at going through alternative processes, best of all when it works, people always remember your print ! and are amazed. Im trying to take a get a photo for my friends 5 year old son and see the look on his face when he realises his face in actually on a leaf !, If the next lot are successful I will post a pic up (although bear in mind its all just an experiment at the mo !)
