Any hope for touching negatives?

Of course you took a DSLR backup of it, didn't you?

Otherwise, chalk it up to experience and try again later.

Looked up, saw the scene, took the shot, loaded a new sheet, looked up and it was gone. Just a couple seconds in all, there wasn't time for anything more.

I don't mind experience, it's when you think you're doing everything right and something comes along and screws it up for no good reason that makes it frustrating. I make plenty of mistakes and own up to those each and every time and learn from them and then make those mistakes less frequently while moving on to newer and better mistakes - that's okay, that's how it goes. Screwy things happening for no good reason is also the way life is, that's also how it goes. Fortunately there were a few that did turn out quite well so it's not a complete loss, just frustrating.

If the image is there but of low density and contrast, you should be able to scan and then restore it a pixel at a time in Photoshop. Lots of tedious work, but possible if the final print is worth it.

Unfortunately there isn't anything there to work with - it's clear. Looks like the negative buckled in the middle and pressed against the back of the one in front.

It's okay, not the end of the world. I figured it was lost but thought I'd see - sometimes I've scrapped things only to read about how they were actually fixable later.
