Case study: a datalogger for outdoor measurements of light spectra

We have had the chance to collaborate in a programming / dancing workshop to create a fully portable and automated datalogger with automatic exposure for outdoor and indoor measurements.

As a result, video shows the overlay of realtime spectrum from trees, walls and vegetation on top of the elegant dance moves of a professional contemporary dancer. Improptu, no preparation.

The technical part took several hours. The video work and processing was longer than the actual technical work.
