RE: Reala 100 Grain
I know this is an old thread but I have seen the same problem with Reala on my Nikon CoolScan V ED. Very pronounced grain for a 100 speed film. I have now compared it to Ektar 100 and the Ektar has MUCH finer and more acceptable grain. I will go as far as to say that in many cases the Fuji Superia Xtra 400 shots I scan have less apparent grain than the Reala scans. ????? I don't know why, I'm still relatively new to this. I use local stores that develop C41 with Fuji processors so maybe it’s related to that. After shooting about five rolls of Reala at ISO 100 to ISO 50 and getting what I consider grainy results for ISO 100 film at resolutions from 1600dpi to 4000dpi I am frustrated.
I have had a few scans of Ektar shot at ISO 100, with excessive grain, most notably in blue sky. I think you mention in one of your articles that the gain on blue channels on scanners may be higher to compensate for the loss of light due to the orange mask resulting in potentially more noise in that channel especially if the signal is low to begin with. I shot my second roll of Ektar at ISO 64 resulting in finer grain than the roll I ran at 100. At 4000 dpi grain was there but finer than any other negative film I have scanned; at 1800 dpi it was detectable but essentially negligible. Regardless it is frustrating when you're not getting the repeatable quality you think should and you cannot find the cause.
