Here is a more detailed version of what I tried to explain.

The main difference with a full DOF plugin is that you will end up having some minor deffects along transitions between shades of grey in your gradient.

A way to reduce that is to apply a gaussian blue to the gradient image itself before copy / pasting it into your mask .

As with many things, a lot of practice is necessary to get it right.
