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.
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.
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:
This week’s Picture of the Week was taken by Lytro’s own Eric Cheng, and shows not only an excellent depth image- and depth composition, but also the perfect use of Living Filters.
Have fun exploring the picture, and don’t forget: Click to refocus, click & drag to shift perspective.
Those of you who are using lfpsplitter to extract data and image stacks from LightField files have no doubt already noticed this, but we thought we’d bring it out to the open:
With the introduction of the new Perspective Shift feature last December, Lytro has made some changes to the structure of -stk.lfp files which effectively break lfpsplitter’s functionality.
