With the arrival of my New Nikon scanner, I tried a few old old negatives, Tri-X, and found the glassine sleeves they'd been stored in wrecked them badly, with scratches everywhere.

I vaguely recall when I was doing my own darkroom duties, that rubbing the negative against oily skin (nose/forehead) on the film base would reduce the scratches when printing. I assume that would also be true for scanning. Does anyone recall this fact or fable? If so, do you rub the emulsion side or shiny side?
 
I've heard those tales too...you would want to apply anything to the side that has the scratches...
Edwal also makes a product called "No Scratch" that works very well...apply with a fine brush and then clean it off after your done...
 
Thanks. That helps. I'll try it with "nose oil" first and it that fails, I'll try Edwal. Thanks for the fast answer!
 
"nose oil" goes on the base side, not the emulsion. The idea behind it is that it defuses/disperses the light where the scratches are so it won't show up during print. I would think it works for scanning, but you'll have to confirm :)
 
I used vaseline/white parafin (very small qties) rubbed on the back side of the film and it works great.
It fills the scratch with something with aproximately the same refraction coef than the film base and so the light goes through ok.

for scratches in the gelatin, you're doomed...
 
I got a commercial no-scratch solution at the surviving real camera shop in the area.

It's really meant for optical printing with an enlarger, but it does work for scanning too.
 
Actually it was called "nose grease" back in the day.

Nose Grease? That doesn't help. Maybe even sounds worse.

Anyway, I tried it and had some success. I see I need to clean my old negs first, so I have an order in for PEC-12 and some PEC pads. AND some Edwals, since the nose is kinda dry and more grease free these days.

Noses are funny places to wander around. You could easily get lost there. Make sure you obtain the stuff from the correct location.
 
For when the scanning is done, there's the free program Polaroid Dust and Scratch Removal.
A useful filter, however in the photos I'm rescanning, the subject wears a veil, the filter ruins the fabric and turns the photo to a gray mush. But otherwise, Polaroid is a great filter.

Same on Andreas Feininger's manual, but he clearly says to use it just for printing and then gently rubbing it off with, if I remember well, "toluene".
