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.
- tecleandor 5y agoI 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.
- shagie 5y agoOn 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.
