Lytro in Linux: Lyli Aims to Become Open-Source Alternative to Lytro Desktop [Updated]

Lytro in Linux: Lyli Aims to Become Open-Source Alternative to Lytro Desktop As exciting as the technology is, not everybody has access to Lytro’s light field tech due to their computer platform of choice. For the obvious reason of limited resources and man-hours in a small startup, it took the company an additional five months from the release of their first-generation camera to expand from Mac-only software to Windows, back in 2012. Linux, on the other hand, continues to be “not currently on Lytro’s roadmap“.

Lyli is a work in progress, but the developer has big plans for his application: Continue reading
