This is impressive, and I hope you'll forgive my rather pedantic comment, but it seems to me you've got the terminology the wrong way around. What you've got here is a process for reducing depth of field, not adding it. In the rendered examples which are labeled on the left, "No depth of field", I'd call that: "Infinite depth of field". Though of course looking at the pictures makes the intended meaning clear in any case.
