I was able to locate a local lab to make Ilfochrome, the replacement for Ilford's Cibachrome. The 16x20 enlargements retain the saturated color of the Fuji Velvia 4x5 transparencies and have the unique luminescence, almost porcelain appearance, of the discontinued Cibachrome. Ilford's website indicates that the new material is available in three contrast grades. I highly recommend Ilfochrome for special prints from transparencies.
