Video: Raytrix demonstrates R29 LightField Features

With their newest Youtube-Upload, German LightField specialist Raytrix demos the LightField features of their R29 camera.

The HD video includes original footage recorded with the high-end camera (resized from 3288 x 2192 = 7.2 megapixels; and 100 % crops), and demonstrates the reconstruction of 3D information – even at a subject-to-lens distance of 400 meters – as well as software refocus and extended depth of field.
Video frame rate for full-resolution imaging is 5 frames per second.

Video: Introducing the Stanford LightField Microscope

The following video, brought to our attention by reader Alejandro, shows how LightField technology can significantly augment traditional microscopy:

The advantages are numerous, and represent the “ordinary” LightField Features but applied to microscopy: Instead of just a single “head-on” orthographic view, a plenoptic microscope setup allows for software refocus, increased depth of field, focal stacks, oblique orthographic views and perspective, 3D reconstruction and volume rendering.

Software Hack: Interactive Picture Refocus for ordinary Digital Cameras

Software Hack: Picture Refocus for ordinary Digital Cameras So you like the interactive Refocus feature of Lytro’s LightField Camera, but not its 400+ $ pricetag?
There’s a way to achieve the same effect using an ordinary DSLR or Compact System Camera (interchangeable lens camera), and in this post, we’ll tell you how to do it!

Toshiba announces tiny LightField camera module for Smartphones and Tablets

Toshiba announces tiny LightField camera module for Smartphones and Tablets, Ready by End of 2013 (photo: Takashi Kamiguri) LightField tech is slowly conquering new fields of photography: Less than a year ago, Lytro shipped the world’s first consumer LightField Camera, which represents the miniaturization of an entire room full of cameras, the Stanford Multi-Camera Array.
Just before the end of the year, Toshiba announced a camera module that is again a miniaturization of the Lytro LightField Camera: The tech giant has packed a microlense array of 500,000 lenses (30 µm diameter each) into a camera module that measures just 1 x 1 cm, which makes it potentially suitable for inclusion in Smartphones and other mobile technology.

Lytro Specifications: A Deeper Look Inside

Are you really interested in the details of Lytro’s LightField Camera? Is the official information not enough for you?
Lytro Specifications: A deeper Look Inside (Illustration: NY Times) Here are some interesting bits & pieces of information about Lytro’s LightField Camera that have accumulated in my virtual notebook over the last few months.
All of these details were mentioned on the web and/or in public presentations (sources are given at the end of the article), but they’re not quite as publically available as the standard information. One of these presentations was a technical introduction to plenoptic imaging by Lytro CTO Kurt Akeley at the University of Washington, titled “A different perspective on the Lytro light field camera”.

How many microlenses are in a Lytro camera?
