A Rendez-Vous with Time

The solargraphy technique was invented in 2000 by Sławomir Decyk, Paweł Kula, and Diego López Calvín. It allows one to record tracks of the sun in the sky during extremely long exposure times. It is a combination of pinhole photography with a totally innovative approach in the use of photographic paper.

Black-and-white photographic paper is photosensitive by itself. Incidental light causes blackening of the paper without any chemical development. This property of the paper was known for a long time, but due to the low effective sensitivity, has not been applied.

No one had ever planned to expose photographic paper without the use of developer and fixer. The use of a dry paper in combination with pinhole camera extends exposure times from one day to six months or longer. The amount of light which goes through the pinhole (with a diameter less than 1 mm) makes moving objects invisible in solargraphs. The only moving object that can be seen in the solarigrafs is the sun, appearing as dashed curves because of the clouds.

We can see the reality as it if it were visible, when our blink of eye will last for half a year.

Maciej Łukasz Zapiór

1982 Wrocław, Poland

Zapiór finished his Ph.D. studies in 2013 on solar physics. His field of interest is dynamical phenomena in solar atmosphere. He studies solar prominences using ground-based and space-based telescopes. Since 2013, he has held a postdoctoral position at the University of the Balearic Islands, Palma de Mallorca.

Zapiór is interested in science-art connections. In 2005, he discovered solargraphy, which is a perfect coupling of pinhole photography and astronomy. 

He has exhibited in Poland and Spain, is the author of several articles about solargraphy, and an amateur filmmaker.
