There's more...

Something we saw in one of the last steps of this recipe was the chromatic aberration effect. Even though we used it to emphasize the weird sensation it can cause, it is sometimes used as a cheap alternative to anti aliasing. This is due to the fact that low values for that setting don't introduce a lot noise or strange artifacts; all they due is push the boundaries of the different objects in the scene in a very subtle way. This can create a similar effect to that added by anti aliasing when done in a subtle way. 

Whatever the case, all of the previous effects should be used carefully and with taste. Overuse is always a cause for disagreement; some people might like the effect but is usually ends up looking dated given enough time, and it can look like a gimmick. On the other hand, subtlety can go a long way, as even though the effect might not be so evident it still adds to the granularity of the image and can add detail to the scene.
