Lytro brings a distinctive new form factor to the digital camera, and a new twist. Different areas of the images can be refocused after the fact, by touching the camera's LCD screen or editing once it's been imported to a computer. The newest feature that light field technology enables is perspective shift. The Lytro camera
is available in a variety of colors and costs $399 for an 8GB model and $499 for a 16GB model.
