Why is 11x14 three times the price of 8x10? Um, competition, supply and demand? I'm sure that it wouldn't be that expensive if Fuji were supplying 11x14.
Of course, a sheet of 8x10 is about twice the price of a roll of 35mm. Is that fair? That's life.
This means that in order to drive down the price of ULF color film, not only must be film popularized, but film in huge and unwieldy formats must be popularized.
