Lytro cameras

 

The newly announced Lytro Illum is the first high-end camera to use light field technology, and it's the second camera from the company. Unlike traditional photos, light field images can be refocused after you take them - so if you'd rather look at the background than the foreground, you can change the focus with a click.It's enormously clever and has the potential to revolutionise photography. But Lytro is a real underdog here: its images require a plugin to view and it's taking on a massive and well established market. Fans hope it will become the Dyson of digital photography.
