Iskiography

Computerized video processing technique, used to depict, in a single image, the tracks of bird flight paths recorded in numerous video frames.

Iskiography (from Medieval Greek ἥσκιος iskios, "shadow" and γράφειν graphein, "write") is a computerized video processing technique, used to depict, in a single image, the tracks of bird flight paths recorded in numerous video frames, invented by German photographer Lothar Schiffler.

The digital processing takes advantage of the silhouette effect of photographing flying birds against the bright sky, combining the bird images from multiple video frames into a single multiple exposure photograph. The software, developed by Nikolai Klassen, solves the challenges of selecting the best subset from the thousands of frames captured in the 50 frames per second video, and of removing the disruptive silhouettes of insects flying close to the camera.

Lothar presented his photo-art project "AIRLINES - Bird Tracks in the Air" at the Fifth International Swift Conference, held in March 2018 in Tel Aviv.
