Light works

Interesting outdoor exhibition in the Royal Academy courtyard by the Royal Photographic Society to mark the International Year of Light.

The show looked at how data can be displayed in different photographic formats. It defined light as “a wave moving through the electromagnetic field present throughout the universe” and talked about how we can use light of different wave lengths to exploit its ability to carry and record information.  OK I’ll admit I didn’t always understand the science but some of the images were fascinating and beautiful.

My favourite picture was the one in the photograph which shows data from three space missions mapped onto globes. I also liked the x-ray picture of people kissing by Hugh Turney and of chocolate shells in an infrared heater.
