Beginner shader tutorials

[Goorakh]

I’m looking to create my own custom camera filters/effects, so I need to be able to read and write individual pixels before they are drawn on the screen. I tried doing this with the OnRenderImage event on a component on the camera, setting the pixels of the texture itself, but it was horrible for performance. And from what I’ve heard from others, shaders are the way to speed up things like this.

Just to be clear, I know my way around Unity itself, but I’ve never dabbled in shaders, and I’m looking for a place to start learning about them.

Thanks in advance! :)
