This company makes a software product called "Halide" for your mobile camera, AFAICT it is an iOS app [1].

But interestingly enough there's an image processing programming language called halide, too [2].

This comes up every time a post makes it to Hacker News. I can only speak for the camera app, but I assume the language also refers to silver halide, a chemical used in film photography.
