This node affects all values within the image in the same way: literally adding to them. Positive values will brighten all parts of the image. As a stand alone color manipulation it is of limited use, though it is ideal for lightening the blacks of distant objects.

Below is visualized an add value of 0.25. It's effect upon a black to white Ramp can be seen: blowing the light grey values into white, and the blacks into dark grey.

An add operation visualised.
