It seems to me, based off of their sample picture that the advantage would not be so much in getting one single frame where everything is in-focus. Instead I would be more excited about being able to "change" the focus after the photo is taken. I assume that would be equally possible with this camera (depending on how the raw data is stored).

For artistic purposes, changing the focus may make sense indeed. For most other (e.g. sensing) applications ... why would you want to ruin your data by applying a convolution to it and losing information?

About a decade ago, I had one of those rectangular Lytro cameras. https://en.wikipedia.org/wiki/Lytro https://en.wikipedia.org/wiki/Lytro And yes, you could change the focus on a picture that was hosted on the web. Unfortunately, those photos, as they required the Lytro site to work, no longer work and I can't find any working archives of them. ( Lytro is winding down https://news.ycombinator.com/item?id=16705391 https://news.ycombinator.com/item?id=16705391 ) But yes, you could - the Lytro's first camera section of https://youtu.be/m8c1__yzX2Q https://youtu.be/m8c1__yzX2Q showed some of the refocusing.

  I got a Lytro ILLUM to test before they began selling it in Spain years ago. Seemed like an interesting toy, specially the depth map that was unusual for that time (now there are cellphones capturing depth maps with different techniques). If I check my NAS there's the dump of the SD card I used that day, but I wouldn't know how to open those files or process them, as I guess the software is not available anymore and I don't know if anybody has hacked the file format.

    On the Lytro, it had a filesystem with an image viewer for the raw data in the camera itself (plug it in and there's a disk that shows up). I'm not sure if the Illum had a similar tool for manipulating the raw data that was part of the camera that was sent.
