Diego Lopez Calvin send me a document photograph of the view in front of the can he has fastened in Valonsadero, Soria, Spain. The exposure was from 17 February to 3 July 2008. Compare the solargraph to the panorama photographed by Diego.

For example an embroidery needle works very well.

This absolutely amazing. Stimulates new interest in pinhole photo. How can you make a hole so small so exposure will be accurate over such a long time?
