I was watching the BTS doc on The Last Jedi and noticed every scene had a little white eyesight dish next to the camera. I sent a message to Steve Yedlin (the DP) and asked him what it was. He said that they attached a few LiteRibbon Hybrid Color LED strips inside of a Bowens Beauty dish to have a soft fill, or an eye glint.

I researched what it takes to create this and made one. If you'd like to see the process and parts list, check out the Imgur post below.
