The refocusable range
The Living Pictures captured with the Lytro ILLUM can be refocused, just by tapping. This ability to refocus is remarkable, but
it does have limits — what we call the refocusable range — for every picture. The refocusable range comprises all the points
brought into relatively sharp focus after a picture is captured.
The refocusable range is made up of two component ranges: the near refocusable range, which is closer to the camera, and the
far refocusable range, which is further away. Each offers a spectrum of relative sharpness, depending on the depth to which the
image is refocused.
In the illustrations that follow, the brighter the shade of the blue or orange band, the sharper objects at that distance will appear
when refocused. The brightest band in each component range is its peak — where objects will appear sharpest when refocusing.
