The sharper the shadow edge, the sharper the edge of the form. The softer the shadow edge, the rounder the form. Think of shadow as a turn in form, intensity depends on light position paired with how hard or soft the form is. Compare a box to a cylinder. The box always has hard edges, and every panel of the box will be a single value, yes? With the cylinder, your only hard edge is the sides and the top, the rest of a cylinder is very smooth, it is not a point like a box edge but a slow constant roundness.

Lost edge is an artist's abstraction to create interest. Think of it as softer than a soft edge. It is where form gets lost in shadow or value - where you might want to render out all forms, you choose to lose an edge in the shadows, making it interesting. The brain very much enjoys filling in the blanks of these lost edges.

Blended is between soft and lost. It is a subtle change, almost lost in shadow but barely the form shows through.
