Adding a Digital Overlay to a Camera Viewfinder
Channel: volzo
Date: 2022-12-11

More than 10 years ago Fujifilm released the X100: a fixed-lens camera with a fancy (new) type of viewfinder: a combination of an old-school optical system with a shiny digital overlay image. 

I wanted to know how to make one myself for a project and that info was surprisingly hard to find. Here I share what I learned and explain (through a historical perspective) how you can get to the fancy modern hybrid viewfinder.
