I tried neopan 400 once, several years ago, and my guestimation for development blew the highlights out so far that the nightmare of printing it has kept me from ever trying it again. Though with so many fans of it here, and since I have become a fan of Acros, I might give it another go but I am curious as there is no mention of the grain relative to other 400 speed films. How grainy is the Neopan compared to Tri-x, or HP5 or Tmax 400? Developed in Rodinal will it become total grit? I am concerned with the 120 and 4x5.
