Washing - photo flogreenspun.com : LUSENET : B&W Photo - Film & Processing : One Thread
On the film base side I got small dust along the film -on right side when you facing film base (not emulsion side). The Question is what you doing after 30 min Washing (every ditale counts) - please. I am talking about 35 fi

If I understand you correctly, you still have spots (dust?) on your negatives even though you have washed them 30 minutes and this is a real problem because it is 35mm. I doubt it is dust as you surmise but I guess it could be. You might try using a film cleaner like that made by Edwal. I have had mixed success using it and you might want to try a small area first. It this doesn't do it and someone else can't help then I guess you will just have to get good at spotting--it happens to all of us.

Using Photo Flo, I could never get rid of all the water spots on my film. Try using Edwal LFN, one drop in 500ml of distilled water, for a final soak. Hang to dry in a dust-free environment.

Use distilled water and Edwal LFN; no more water spots.

What you describe sounds like dust adherring to the film when the emulsion is still wet and soft. Try hanging it in a bathroom after you have run the hot water in the shower. Better yet, run the shower and then hang the film in the shower. There is an increadible amount of dust in our homes especially with any kind of rugs or carpets. The emulsion is very soft on wet film and it acts like a magnet. Photo-flo won't help with this problem. And too much photo-flo is as bad as not any. When your film dries it looks like water spots but it is dried photo-flo which is nothing more than soap. James

I've had great results with Photo Flo. I after rinsing my negatives 12+ times (still on the reel in the open canister), I add a few drops of Photo Flo to the empty canister, fill slowly, let sit for about a minute, then rinse again about 10-12 times. It's also important to hang your film to dry in a relatively dust-free area.

If you rinse your film after using photo-flo you completely negate its effects. Photo-flo should be used sparingly (about half strength) with distilled water as a final rinse.
