It is an exhibition of twelve images that have the Sun as the protagonist in different latitudes of the Earth. They are photographs of very long exposure that establish a dialogue with the landscape over a period of time marked between solstices and equinoxes.

Traveling through them, it is possible to imagine with greater precision the invisible paths described by the sun in the sky and to better understand some details of celestial mechanics.

This project or concept bridges in an original way between the beginnings of photography in the 19th century and the modern digital techniques of the 21st century. It directly relates photography as a means of expression, with astronomy, meteorology, internet, geo-localization, knowledge of the environment or agriculture.

Solarigrafía” is a word invented by Diego López Calvín, Slawomir Decyk and Pawel Kula in 2000 to introduce this concept and way of photographing the Sun from what they called on the Internet the “Proyecto Solaris”.

Diego López Calvín


Graduated in Information Sciences, U.C.M. of Madrid, he is freelance photographer.

In 1999, together with Slavo Decyk and Pawel Kula, he started the “Solaris” project, where a group of photographers used pinhole cameras for two consecutive years to compare the traces of the sun at different latitudes of the planet. This artistic project that unites art and science will give birth to Solarigrafía, on which he continues to work.
