I cannot see the worth of this film for contact printing as grain is so very fine. Its real value is in large enlargements. It is unlikely to produce enough grain and edge for biting sharp contacts no matter what its dev'd in. I have used it with Dixactol in 5x4. Grain still effectively invisible at 20x24. I would probably not want to use it in 10x8 unless prints were exceeding 40" plus as other films would still give grainless prints with lower cost and (for me) the preferable look of traditional films.
