These are some of the nodes and techniques explained in the Blender Compositor Tutorial - Introduction. cause let's be frank. Copy pasting nodes by hand is for stone-age monkeys. Just append into your project, or your startup file.

Nodes released:

• Custom Pixelate (Mosiac censoring of various levels of blur.)

• Chromatic Aberration (Fancy pancy color-shifts.)

• Vigenette (Babby's first point of focus effect.)

• Watermark Node (Quick watermark setup so you don't have to repeat the steps everything.)

• Watermark + Downscale Node (Same as above, just in-case you choose to make a higher res final render.)
