Lecture 11: Radiometry (51)

If you haven't taken CS194-26, you should check out the Stanford Multi-Camera Array (http://graphics.stanford.edu/projects/array/) pictured here. It's made up of 128 carefully placed cameras.

There's an archive of data captured by this array in the Stanford Light Field Archive (http://lightfield.stanford.edu) which contains some structured data that can be used for light field processing.

This data can be used to simulate depth of field effects, aperture readjustment, and even slight rotations. The cool thing is that this can all be done with images that were already taken! This is the project we did in CS194-26 (https://inst.eecs.berkeley.edu/~cs194-26/fa18/hw/proj5/index.html).

Adding onto the post above, the reason for doing this whole procedure is so that you can change focus and aperture effects after taking the photo. Our professor (Ren Ng) is in fact founder of a company that creates these cameras in portable form: Lytro cameras, which are awesome. For example, a good use of these cameras is for street photography. If you don’t have time to focus on the subject while moving or while the subject itself is moving, using this camera solves this problem. All you have to do is take an image in the area of the subject and change the focus in post. https://www.youtube.com/watch?v=4qXE4sA-hLQ
