lfpsplitter: Update for Images processed with Lytro Desktop 2.x

Lytro’s recent upgrade to Lytro Desktop 2.0 entailed some file format changes that rendered light field files incompatible with lfpsplitter.

An update to lfpsplitter, provided by Elissa Weidaw, now accommodates for these changes and makes lfpsplitter usable again. The author has made sure to keep the lfpsplitter syntax unchanged.

Since Lytro Desktop 2.0, LFP image stacks are encoded as H264 frame sequences – used to compress files and speed up loading times. Due to “legal issues swirling around H264 decoding”, lfpsplitter does not decode said sequences. There are, however, other tools (e.g. ffmpeg) that will do the extra step for you.

Lytro Desktop v. 2.0: Perspective Shift Update also brought Colour Enhancements

Lytro Desktop v. 2.0: Perspective Shift Update also brought Colour Enhancements About a month ago, Lytro released version 2.0 of their Desktop Software for Mac and Windows.
The update included not only the new Perspective Shift and Living Filters features, but was also the first version to officially support Windows 8 64-bit. Another new aspect of the software, to be comprehensive, is the possibility to change the Lytro Library location from within the software interface.

Among the usual “Miscellaneous bug fixes and improvements to performance and stability”, however, we found another quite strong improvement: It looks like the latest Lytro Desktop version makes up for some pale, washed-out colours, and greatly enhances color representation in (at least some) pictures.

How to Create Stereoscopic Cross-View 3D Pictures from Lytro Images

The newest feature to be added to the LightField capabilities of Lytro’s Destkop Software is Perspective Shift: Viewers can physically move the point of view a few centimeters in every direction, within the limitations of the lens system.
In order to create this stunning effect – remember, these are pictures taken with a single lens! – Lytro uses a combination of parallax information and an infinite depth of field version of the picture in regard.

With these two sets of data at hand, it is just a small step to create 3D pictures, and Lytro has already confirmed working on a 3D Export feature. But why wait? Using Perspective Shift, it is already possible to create stereoscopic cross-view 3D pictures.

Lytro-Fan and beta tester Jeff Wilson tells us how it’s done: Continue reading

LightField Picture of the Week: Plasma Globe

You’ve probably come across a plasma globe in the past: It’s a glass orb filled with various noble gases, and a high-voltage electrode in the center. When turned on, it displays moving purple to pink plasma filaments, and if you touch it, they lock on to the position of your fingers and intensify.
Lytro user tip184 has taken an interesting picture of such a plasma lamp with a Lytro camera, and it’s our Living Pic(k) of the Week:

Be sure to try Perspective Shift (click and drag around) with this one!
