What does the Fujichrome F suffix mean?

[Leigh]

Some films like Velvia are available in both 100 and 100F versions.

What's the difference?

The non-suffix version appears to be slightly finer grain and sharper.

Both versions have an RMS granularity of 8.

If I remember correctly, F stands for Finer because it has an extra layer of color. The differences are numerous.

Seems to mean "flatter colour". Kind of. Not that there's anything other than RVP100 available now in both F and non-F.

I'm not going to make wild guesses. If i remember correctly, 100f came out prior to velvia 100 as an alternative to rvp. Many folks didn't like it.
Then there's also astia 100f.

I thought it stood for "Fuji" :)

You know, sort of a Deja Vu! :)

Shouldn't that be "Deja Fu"? :D
