The future of Photography?

Cameras have changed vastly in the last twenty years. How much more can they change?

Well, for the camera nerd of the future, one place worth checking is Federico Capasso’s research group at the SEAS school at Harvard University.

They are developing the “metalens”- a nano engineered array of titanium fins which reflect light to a focus. Produced using similar photolithographic techniques to those used to make microchips, these are flat, glassless lenses. While they are unlikely to replace traditional “big glass” next week, metalens technology may well be the way forward for photography in the long term. Worth Googling.
