Lytro. Lenticular 3D. Reverse Engineering the Lytro .LFP File Format. After getting my Lytro camera yesterday, I set about answering the questions about the light field capture format I had from the last time around. Lytro may be focusing (pun absolutely intended) on the Facebook using crowd with their camera and software, but their file format suggests they don’t mind nerds like us poking around. The file structure is the same as what they use for their compressed web display .lfp files, complete with a plain text table of contents, so I was able to re-use the lfpsplitter tool I wrote earlier with some minor modifications. The README with the tool describes in detail the format of the file and how to parse it. The table of contents in the raw .lfp files gives away most of the camera’s secrets. It contains a bunch of useful metadata and calibration data like the focal length, sensor temperature, exposure length, and zoom length.

Syncing the camera to Lytro’s desktop software backs it up the first time. Thank you for purchasing your Lytro camera. Astein. Echeng. Iellison. Goolie. Throwable Panoramic Ball Camera // Jonas Pfeil. Ball Camera (@ballcamera) sur Twitter. Cryptocat.
