I developed a roll of 120 last night with straight D-76 (my little kitchen stays cool, and I kept the chemicals right in font of the A/C). I miscalculated the volume needed to completely cover the expanded Paterson reel, and had to race to add a few mls. So, the negs look great except for a quarter-inch edge the length of the strip that had 30 seconds or so less development.
AND, I discovered the light-tight Paterson funnel does NOT lock in the normal position with spout down in the small Super System 4 tank, which I should have checked before going dark. It does lock with the spout pointing up (?).
Aieeeeee! I had to race about to go from developer to water to fixer, covering and uncovering with the tight lid. This discrepancy is NOT listed in the Super System 4 instructions ...
