~ the goodbye ~

lytro was the gadget computer engineers paid attention to and almost nobody bought. ren ng's stanford thesis on light-field imaging was the kind of paper you opened in a graduate seminar and felt your worldview shift. focus-after-the-fact. depth maps from a single shot. then ng raised $140m and tried to ship it as a consumer product.

the first lytro came out in early 2012 as a small black-and-aluminum tube that did not look like a camera and did not produce images that looked like camera images. the second one, the illum in 2014, tried to look professional and tried to charge $1,600 for it. neither sold the way the funding round assumed they would. by march 2018 the company was gone and most of the engineers had moved to google.

i never bought one. they were not really sold in turkey at retail and the people i knew in computer vision had the same reaction to it. the math was good. the photos were strange. you got a 4-megapixel-equivalent flat image plus a tiny refocus window on the export. it was not a phone camera replacement. it was a thing you bought to show people that focus could be a slider.

~ the math that survived ~

the strange thing about lytro is that the technology was not wrong. plenoptic capture and depth-from-defocus rendering are now standard tools in computer-vision pipelines. apple's portrait mode is a light-field shortcut in software. google's pixel camera does something close in its hdrnet stack. the difference is that none of them tried to sell you a separate device for it. the math became a feature inside the phone you already owned.

~ the actual end ~

lytro's last move was the immerge in 2015, a giant sphere covered in micro-lenses meant to be the cinema rig that brought light-field capture to vr filmmaking. rental price was in the $250k range. exactly the wrong product for 2017 vr, which had no theatrical pipeline. the company laid off most of its staff in late 2017, posted a "next chapter" page in march 2018, and quietly transferred everything to google. the patents are still there, somewhere inside alphabet's vr group, which itself has been wound down without ever shipping a successor.
