camera shader

General

I am starting to look at shaders. It is so exciting to process camera input live! Here is a basic attemps to improve the dark regions of the image. There are sliders to:

  • choose the camera.
  • increase the light (0/1/2).
  • increase the color saturation.
  • filter the noise out.

--displayMode(FULLSCREEN_NO_BUTTONS).
remove the --
I had to comment this line to put it on CC

Does anyone have this code in among their old projects? It looks a lot like an extremely simplified version of the new Shaders app, a version that only does one thing. It seems cool.
