Calibration is an important part of light field photography: Image processing and image quality can be significantly improved when the physical properties of the camera are known. More specifically, geometric information about the microlenses in a microlens-array-based light field camera can help create more precise depth maps with fewer errors.
Yunsu Bok and colleagues from the Korean Advanced Institute of Science and Technology (KAIST) have devised a new method for geometric calibration which – in contrast to conventional methods – does not rely on processing sub-aperture images. Instead, they extract line features and compute a light field camera’s geometric parameters directly from RAW images. Continue reading →
Lytro has released a list of third-party accessories that have been successfully tested with the Lytro Illum light field camera.
The list contains different kinds of cases (carry bags, holsters and sleeves) and straps, and an as-of-yet limited collection of suitable tripods, flashes, LCD hoods/shades and timers.

So your Lytro Illum has finally arrived – now what? In many respects, light field photography is fundamentally different from traditional photography, and the switch from one to the other may not be an easy one for everybody.
Josh Anon, nature photographer and former Senior Product Manager at Lytro, recently published a new ebook titled “Using Lytro Illum – a Guide to Creating Great Living Pictures“.
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!
We had a closer look at whether the book delivers what the title promises, and in this article, we’ll tell you what we think.
Light field technology produces a completely new, and fundamentally richer, set of data. With all of the advantages of this technology, the obvious downside is that there isn’t yet much software out there to process this data.
Now, the Fraunhofer Digital Cinema Alliance has presented a light-field plug-in for the popular video post processing application Avid Media Composer.
According to their press release, the software plugin is able to create high-resolution depth maps, change focus, move perspective or add 3D effects and camera movement. The output can then be used to generate footage for 2D, 3D or multi-view displays — and all of that by using existing video software. A licensing model is available for professional users interested in working with light-field video.
ExifTool is a popular piece of open-source software which allows users to read, edit and write EXIF metadata from/to images and video. The newest update to version 9.70, released earlier this month, adds support for Lytro RAW files and enables us to read EXIF metadata from Light Field Picture (LFP) files.
