1. Introduction, light field cameras

This page is new and under construction.

There are a lot of applications to Light Field, you maybe have read about the Lytro cameras that you can focus AFTER you had taken the image:

• https://en.wikipedia.org/ wiki/Lytro (Lytro, Wiki)

Now its big brother has come:

• https://www.dpreview.com/ news/6149054684/ lytro-immerge-2-0-is-a-huge-light-field-camera-rig-for-high-end-vr-production (Lytro Immerge, DPReview)

This technique is very exiting and what can be done with it.

2. Light field theory

Here I have collected links with information about the Light field theory:

• https://en.wikipedia.org/wiki/Light_field (Light Field, Wiki)
• https://en.wikipedia.org/wiki/Light-field_camera (Light Field camera, Wiki)
• http://blog.lytro.com/what-is-light-field/ (What is Light Field, Lytro)
• https://www.youtube.com/ watch?v=uNqWqIdK7JM (What is Light Field Photography?, Youtube)
• http://graphics.stanford.edu/ projects/lightfield/ (Light fields and computational photography, Stanford)

I add more links later.

3. What Light Field cameras can do

Take a look at this movies to see examples of what a light field camera can do:

• https://www.lytro.com/ (Lytro)
• https://vimeo.com/ 161949709 (Lytro Cinema, Lytro)
• https://vimeo.com/ 130983212 (Breakdown Comming Home, Fraunhofer)
• http://gl.ict.usc.edu/LightStages/ (The Light Stages, VGL)

Green screen and 3D:

• https://www.extremetech.com/ extreme/226386-lytros-new-cinema-camera-will-allow-3d-movies-to-be-shot-using-light-fields (Extremetech, Lytro)

I'm sure we will see a lot of this as special effects in movies from now and in future.

4. Light Field and astronomy

And of course I think about how this technique can be used in other ways with specialized software. Maybe even in astrophotography, seeing killer?

Application of Light Field in astronomy:

• http://graphics.stanford.edu/ papers/ stabilization/ (Image Stabilization, Stanford)
• http://graphics.stanford.edu/ papers/ glare_removal/ (HDR & Glare, Stanford)
• https://en.wikipedia.org/ wiki/ Adaptive_optics (Adaptive optics, Wiki)

Adaptive optics is the most common and are not new. But new technology and powerful computers can make it more advanced. The more advanced systems have "rubber" mirrors that they bend to correct the incoming seeing disturbed wave.
