Last frames from the diafine roll. Some bromide drag happening here, will need to increase inversions or start using a stainless steel tank.
3200-4000 (can't remember) Very thin, but certainly usable for scanning.
You can really see the contrast picking up from this point on, mainly because the roll is finally rated at 1250 (best speed for diafine)
Actually, there might be another part. Still a few frames from this trip on another roll :)
