There is no substitute for it, AFAIAC. It is the best medium speed color neg film made, period, and nothing comes close to its look, IMNSHO (except for Superia 100, which also seems to be gone in 120). All the Fuji Pro and Kodak Portra films are quite different from Reala, and far from "neutral" and "accurate" in my eyes. Fuji Pro S and Kodak NC are "subdued", Fuji Pro C and Kodak VC are "exaggerated", and Reala is right in between, or "normal". Reala is like a color negative version of Provia or EPN. Very straightforward and plain, with very little intentionally introduced "character". As far as I can tell talking to various retailers recently, it is discontinued in manufacture, not just in import. I can't seem to confirm this from Fuji, however. If Fuji proper is not responding, the next step is to find out from your local retailer when the next time their Fuji sales rep. will be in, and come in then and talk to that person.
