The National Media Museum in Bradford have discovered and restored the worlds first colour film footage dating back to 1902.

A complicated process, it involved photographing successive frames of black-and-white film through blue, green and red filters. Using a special projector (which you can see in the gallery) these were combined on a screen to produce full-colour images.

The full footage is on show in Bradford, but clips can be seen in the documentary video on the NMM website.
