Recently I wanted to add bloom to a personal project I'm working on. In the Image Effects (Pro Only) package that you can import directly via the editor you have exactly what I wanted, a simple bloom effect. Attach it to the camera and boom you have bloom.
Sad thing though is that the compiler spits out a bunch of warnings when you import that package, clearly it's been a while since the package has seen some love from the Unity developers. I can understand that their priorities lie elsewhere.
Obviously I code in C# and I wanted to add the bloom effect on the main camera and change its public values via code. Since the effect was written in unityscript this was not possible.
So I spent some time converting it to C#, you can download it here if you want to use it. I did not clean the code or anything, just made sure it worked like it did before and that the compiler was completely happy with it.
