I have a hard time distinguishing the difference between soft and diffused.

Me, too. One thing to keep in mind is that a small source will still cast hard-edged shadows no matter how many layers of diffusion you put in front of it. I could speculate (no pun intended) that perhaps the main effect of diffusion is to reduce specular highlights, although I'm not even sure of that. I know from experience what different sources look like, but I've never thought or read enough about it to explain the physics.

I have a 32" softbox that has 2 layers of diffusion, a grid and a deflector plate. The softness is the same regardless of the mix of the options ? The biggest differences I see are:

- bare, no diffusion, no grid, no deflector

- bare with the deflector

- double diffused with grid

- double diffused no grid

Double diffused is the most flattering. I would normally say the softest. I guess this is the wrong terminology ? Adding the grid keeps the light off the background and adds some contrast to the subject.

What is the correct terminology for the differences I see ?

Perhaps SailorBlue will step in here. He seems to know everything and has a knack for explaining complex subjects.
