Solargraphy is a very primitive and simple technique to take extremely long exposure photos. The resulting picture tells a story about changes during the time it were exposed. Still objects like houses, trees and anything else that never move are sharp, while other things, like different cars parked at the same space leave blurry shapes and constantly moving things become invisible. The most interesting part of the picture is the sun. These solargraphy photos were made by Ignas Kutavicius – a Lithuanian artists currently based in Sweden.

Probably every beginner in photography has a bunch of long exposure shots of in his portfolio – usually of a pretty city panorama at night. Although most of us are familiar with the method, Finnish photographer Janne Parviainen took this technique to a whole different level, by tracing the whole room with a single LED light. The artist says that one picture takes around half hour to make, for the exposure has to be open as long as it takes to trace all the objects in the frame (at night!).
