I'm comparing Neopan 1600 and APX 25 on the same image. Neopan appears to resolve more detail than APX, which I think is the opposite of how it ought to be? Also, Neopan appears to be resolving too much detail for the grain size—in a real photo, the grain would destroy some of the detail, but here it's acting as more of a layer on top of the detail.
Yep currently looking into grain for v1.2.0 release, likely coming next weekend. Will be a complete overhaul of the grain pipeline
