But, of course, we put the sheet film holder in FRONT of the ground glass and not behind it. How stupid of me! I mean, really!
OK, a quick question about diffusion. When you put a diffusion filter in front of a reflector, what exactly is the diffuser doing to the light? It's making it softer (????).... but how, what are the mechanics or physics of it?

DEAR BOGDAN, Well, the ground glass remains translucent and shows the image projected on its surface but you cannot pass image making rays through it...they will be diffused.

Opaque to me means light will not go through.Nope, my bad. I have Brooklyn school system education: Opaque \O*paque"\, a. [F., fr. L. opacus. Cf. Opacous.] [1913 Webster] 1. Impervious to the rays of light; not transparent; as, an opaque substance. I thought it meant it let a little light through.
