Using LYTRO ILLUM provides a comprehensive overview of the Lytro ecosystem. Endorsed by Lytro, Inc., this book covers everything from what the light field is to how to take advantage of the Lytro button while shooting to how to edit your pictures outside of Lytro Desktop. It's the one guide that will take you from novice to living picture expert!The latest revision covers the new Focus Spread feature in Lytro Desktop.
Given that the owners manual included with the camera is little more than a pamphlet, this book is must reading. It introduces you to the concepts of light wave photography, guides you with initial setup and shooting your first pictures.
It goes on to detail all the controls, and using the Lytro Desktop software (although it's showing an earlier version of the software, it still gives you a good idea how to use it).
