I am looking for a high speed (preferably ISO 1600) B&W 120 roll film that is comparable to Fuji Neopan 1600 and am wondering what would be the best choice for the film and developer to preserve shadow details, smooth tonality and avoid excessive graininess (I find Delta 3200 and TMY 3200 overly grainy). Would I be better off pulling TMY 3200 by 1 stop or pushing Neopan 400 or Tri-X by 2 stops ? Would the answer to the question be different if I were to settle on ISO 800 instead of 1600 (and take my chances with a slower shutter speed ?) Finally, if I one favors preserving finer grain over shadow details, would Xtol be a better developer compared to D-76 ? Would appreciate suggestions from those who have compared the push vs pull alternatives. Thanks !
