Here's an example of Neopan 400. I'm not sure if anything can even be told from a scan, but this is a 100% crop from a 1200 DPI scan. Good light, this was actually with my Spotmatic F and a Takumar 50mm i think.
Not sure about reticulation to be honest. At the most the difference would be from 20 to about 10 degrees. But this shot was developed in the summer so the water straight from my tap wouldn't have been that cold.
Maybe i'm just not used to what i'm seeing! These are my first own prints. I certainly don't mind the grain too much, just want to make sure i'm not doing anything wrong!
