That's exciting news. Do they have software for the 9000?


I think so. They have a list of 80 some-odd scanners they support.

Ah.

A mechanical detail: my film is cut into six-frame strips. I was able to get the dry onto a ss spiral reel for the water wash and the initial dip in photo-flo. To give them a good rub, I removed them from the reel. What do you do with them for the second sluice in Photo-flo? I used a 4x5 rubber tank but was worried about an edge catching on the emulsion of another negative. And how do you hang them to dry?

As to your lovely wife: congratulations. I dated a Canadian in the late sixties..... I'll find the negatives of her, eventually.

OK- Wash one strip at a time but not on a reel- and tank, bowl or tray will work. Agitate and rub gently but with sufficient pressure to dislodge embedded particles. Squeegee gently and hang on a line made of cord, strig or light wire. Use a film clip, clamp-like paper clip, clothespins, or paper clips in the sprocket holes to hang the film from the line. Use a clip or clothespin at the bottom of the strip to weigh it down. It should dry curl-free.

So, re-washing didn't help. It appears, as was suggested elsewhere, that what I'm seeing is a chemical reaction, probably between the plastic of the sleeve and the emulsion side of the negative. The images in question have been in the "archival" sleeve for about 35 years...
Or it was something in the environment to which the plastic was porous. I've been in one house and three apartments in that period, and though I aimed for a cool, dry, dark place for storage ... Who knows?
Thanks again for your thorough response,

When you said your negatives were dirty, we thought they were dirty and tried to advise you accordingly. If I, for one, had known that the actual problem was emulsion deterioration, I would not have advised any kind of cleaner or, in particular, a solution which could soften the emulsion and only cause more damage. I think the best you can do now is let them dry, make the best copies you can, and correct your mistakes in post. Good luck!
