I'm looking for a relatively easy to understand tutorial for depth of field using Vue 6I.  There is one tutorial here for depth of field in a portrait in Vue and, it honestly confused me.  I'm not DUMB but I sure felt dumb after reading it, LOL.  If anybody can help me out, that would be awesome.  I've got DoF figured out in Poser finally but I really don't like the way it renders :(

Thanks in advance!
