solargraphy, how to do a 6 month exposure, pinhole photography
Tarja Trygg maps the paths of the sun with solargraphs in a global project sending pinhole cameras out for solargraphy at several latitudes.

Kristian Saks demonstrates some absolutely amazing solargraphy - which as it may seem IS capturing the sun's (solar) rays across the course of the day!
View due south across my yard towards the Brecon Beacons. The snow has left its mark! Exposed: 21 December 2012 - 28 April 2013. Paper negative: Ilford MGIV unprocessed. Scanned & inverted.

Leave it and let it soak in the sun. It's that simple. Photographer Kasia Kozińska talks about her recent creative photo project in this interview.

solargraphy photos
Solargraphy is a specialized form of long exposure pinhole photography that registers the sun trails as a consequence of its apparent movement related to the earth (known as “ecliptic”). The image is created using home made pinhole cameras (usually tin cans, 35 mm film canisters, PVC pipe, etc.) charged with photosensitive paper and fixed to some point for a period of time.
I tested different B&W papers using filmcans each with a pinhole of about 0.25 mm. Exposure time: 19.03.-19.04.2011. No editing except for inverting. I hoped to see a more clear difference between the Ilford and the others which are high speed papers. My favorite is the Foma (2). However, the pinhole itself seems to be the most influencal factor on image quality. In my opinion #2 does not only show the most details in the shadows but is also the sharpest image. The pinhole in #4 is simply scrap. 1 Ilford MG IV RC Deluxe 2 Foma Fomaspeed N312 3 Bergger Variable CB 4 Kentmere Fineprint VC 5 Adox Easyprint 312 I know of two similar experiments out there: www.solargraphy.com/index.php?option=com_content&task... and www.greggkemp.com/projects/papers-for-solargraphy
