Shader to a Camera

Hi, the situation : I know how shaders works for an object (i’m a beginner in Shaders) I just don’t understand how works with a camera.

for example, i want to make a camera effect (image effect), searching in the web, everyone uses shaders, in some place there are shaders.

with C# can this be done? or I need to program GPU?

please if anyone can explain it will be helpful

PD : sorry about my english :slight_smile:

If you have Unity Pro, load the Image Effects standard package and have a look. If you don’t have Unity Pro, then it’s not really possible.
