Interactive refocus is nice, but it’s just one of the possibilities of LightField photography. Another feature that LightField fans seem anxious about is “all in focus” – a combination of all the sharp parts of the light field picture into a single, flat exposure.
Lytro has confirmed that all in focus will be possible within the Lytro Desktop software by the end of the year.
Developer Nirmal J Patel didn’t want to wait, and wrote a small python script to create “all in focus” pictures from Lytro .lfp files himself: Focus all parts of Lytro image
Before: A typical Lytro Living Picture with up to 7 focus layers (for web display)
Interesting side note:
Within each .lfp-file, depth information is stored in an array of 20 x 20 tiles. That means, every image is divided into 20 x 20 = 400 squares (54 x 54 pixels at a resolution of 1080 x 1080) with information on focal depth.
