I wanted to share you the finding that I have personally found; grain is actually so small that scanners cannot resolve it like it is. Nothing else. I really don't know what scanner grain is; maybe it is some kind of more clumped grain, please enlighten if you know. I was personally blown away how I've always thought that the scanner grain is the actual representation of film grain and found out with my own hands that it isn't.
As fas as grain in scans goes, I've never seen grain in a scan that looks like the true grain that I see in a grain focuser, for instance. But that's quite a magnification of course, and in my case the 5mm enlarging lens sees even closer than my grain focuser, but of course it can't see the entire negative, only a few millimeters. So that technique is
amazing for doing huge enlargements of tiny sections of a negative. A grain lover's dream.
Please do not draw any conclusions longer than that of my postings here. I also have right to tell my experiences about V600 here without anybody needing to get butthurt about it.
Oh, but drawing conclusions is what we do. Also, "butthurt"? My butt feels great, no worries, no hard feelings, nothing.
