The craziest thing that none of us can figure out...

How about this one...a student using a Nikon camera, removes film...but when she tries to load it onto the developing reel, half way thru the roll, the film starts to curve the other direction. How did it happen?

Looks like she had trouble loading the reel and turned on the safelight for a second or so. Definitely the film was curly mess when the lights went on.

I don't know, but it sure looks like art to me!

Seriously . . . I'll go with the light leaks during loading of the film on to the reel. Bill Barber

I'm not sure of the whole thing, particularly whether she had finished the entire roll before rewinding, but I'm pretty confident that she rewound turning the rewind crank in the wrong direction. I'd bet it was something of a struggle at that.

Based on the "shadowing" I'm guessing that a room light was turned on (or door opened) while the student was holding the film aloft in one hand and it was spiraled downward. The point where the shadow crosses is where the film was actually on the table and twisted around.

The anti-halation layer is enough to block the light from the rest of the negative to prevent fogging of the entire emulsion.

I can guarantee you that when confronted the student will respond with a blank look on his/her face and say "I didn't turn the light on" or "I just used my flashlight".

More likely, I'd say that the student's cell-phone rang and lit up like a Christmas Tree.

It has to have been a near point source to produce a coherent image of the edges of the film and the sprocket holes. Door open doesn't do it. Flashlight doesn't do it because the flashlight would have moved. The film had to be in one place long enough, in a place related to a near point source, to produce a coherent image.
