I agree that there are three things here and they are all different.

1. Inspecting a neg with a quality loupe.

(Make that four)

2. Printing it big with a quality enlarger lens and aligned enlarger.

3. Making a big fat scan out of the neg and checking it out on your monitor.

4. Projecting it on a flat mat screen with a quality enlarger lens
	(which i don't got, just a cheap  Kodak Ektagraphic FF lens 76mm f3.5, which is
probably acrylic!
		but which allows me to tell my K25 from my K64, no grain in the K25, would i
see the grain with a better projection lens?))))
