Frieder Hochheim changed what was possible for cinematographers to achieve when he created the Kino Flo fluorescent lights which finally made it possible to work quickly and in tight spaces with beautifully soft light.  He worked closely with colour scientists at Kodak to solve the complex problems with the way that the colour spectrum output by traditional flouro lights was captured by film.  He's now using the same rigorous science to solve the challenges of how the spectral response of various digital cameras and different LED lights can produce unpredictable colour results.  In the process, he's discovered some game-changing things about LED lights and digital cameras.
