The print came out black because it was not exposed / developed long enough. Going by the development times, it is way too short.
Unlike most pan films, you can develop by inspection (safe light). Keep it going. With Dektol / Film, I need 12 mins - and that's with iso 100. Paper is, about 6?
With film, I need about 12 minutes constant agitation in paper strength Dektol. I had no idea paper required more development than usual as well. I'll give that a try and see what happens. Thanks for the tip
