I need some help on Depth of Field rendering in LW.
I understand that focal distance is the distance (in meters?)
between camera and focused area.
But how does the F-Stop work? is it exactly the way a real
camera's F-stop works? or is this number the percent of
"clarity falloff" from the focused area?
