filmscanners: grain in negs/slides
Why do scans of color negatives appear grainier than those from slides?
I have always read and experienced myself that color negs are less grainy,
especially in high ISO emulsions and that in slides everything above ISO 100
shows pronounced grain (ok - naow we have Provia 400F).
But from what you write and from my first set of scanned negs and slides I
conclude that negs really show more grain that slides. What's the reason for
this phenomenon?
BTW the pronounced grain from my negs I don't consider intrusive in any way.
I'm just curious what's so peculiar in film structures that different
effects are achieved although both types of film use dye clouds.
