I haven't read through too many posts here so forgive me if this topic has been discussed.
I am puzzled by the developing times for Neopan 400 (and 100). When using Fuji's SPD it is very fast, only requiring 4.25 minutes at 20 degrees.
And yet with D-76 this film requires about 6.5 minutes. Neopan 100 requires over 7 minutes. The strange thing is that with most other emulsions SPD and D-76 times are almost identical.
I'm not just quoting "book" times but have verified the above numerous times in my own experience.
Is SPD specially formulated to work on Neopan film faster than others. Is that even possible?
