Weird white line in the negative.
Pulling out the roll from the reel, I notice an odd white line running along the top part of the negative. It's a milky white color, runs the length of almost the entire roll. It doesn't affect the pictures per se, it's just on top of the sprocket holes. Don't know what it is or what cause it, I've developed two other rolls using the same chemicals and they don't have this line. Film used was Legacy Pro (Neopan) 400, developed in HC-110 dil. B. Maybe it was caused while loading (?) since I had a difficult time getting the roll into the reel. Any help?
