How to do remove dust from negatives before scanning??

I have been using a rocket blower. The upshot is that it is improving my firm handshake.:)

I find that having negatives processed and printed or scanned causes MUCH more dust and scratches than having the film developed only and then delivered to me uncut. This is my normal workflow.

 

Then I blow, blow, blow. Call me "blow hard." :)

 

I recently asked my lab what they do, and they referred me to a canned air product called Dust Off XL Plus by Falcon. They say that they use it and that, unlike other compressed air products, it shoots dry air rather than wet air, provided the can is held upright.

 

So I am going to try it.

 

What do others do??

 

Dust is not a huge deal for me, at least not for 35mm film. For MF film it is more of a problem, particularly with B&W where the dust removal feature of my nikon coolscan isn't available.

 

I do find, though, that running the dust removal ever so slightly takes some of the clarity off the image. And it increases the scanning time by a lot. So I avoid it whenever possible.

Have you tried an Arctic Butterfly? It uses static electricity to capture the dust and may work very quickly and not send dust particles in to the air en masse just to be attracted back to the negatives.

thanks, JD and 2WK.

 

JD - is the Arctic Butterfly a product for negatives as well as sensors?

2WK - I have a similar orange cloth and haven't had much success with it. But I will try this one. I Typically will wash and dry my hands between each negative loading and run my fingers across the negative strip before loading it into the carriage, followed by blow, blow and blow... The orange cloth seems to just get in the way, and touch other things that have dust, like the table. Perhaps I'm just too clumsy.

I would think it could be. It is very soft and when it sweeps the surface the bristles would pick up the dust without blowing it all over. If I remember right negatives are loaded with static.

This cloth is a bit special I have come to believe...I think it is coated with something. I pull the whole roll tightly through the cloth, then a quick rocket blow or canned air and it greatly reduces my dust. When I'm not using it I keep it folded and back in its bag. Shake it out before using.

All the above mentioned techniques are cures, which I am sure are moderately effective. However, Prevention is more desirable, if practical for you.

 

Processing and scanning your own cuts out what, in my opinion, is the greatest source of dust and scratches. ie. Anyone else handling your films. Most 'labs' are no longer professional in their processing and handling (yes, I know there are exceptions) and will be the bain of your life.

 

I am fortunate in that I have facilities to process all B&W and colour films. As a consequence, handling and transport is minimal and a simple blow with a rocket blower is the most I ever do, if required.

Henry - what is the noise level on this? How much louder than my rocket blower?

Adam quietest compressor than disturbance of the street :D

Seriously I can not say silent but not noisy either :)

Noisy (a little) only when the compressor is charging

Adam look at this post (in "Other" thread "My new companion")

The compressor Kaeser is on your right

Best

I've eliminated a good bit of my dust problem (before wet printing) by, prior to brushing the negative, touching it to the incoming water line. Bare copper, it runs conveniently through the basement right next to the enlarger. A sufficient ground.

I just pull the neg strip through the index and third fingers. I know some say this will cause scratches but in more than ten years of using Coolscans I have yet to experience that.

I do that, as well. But I make sure I do it with freshly washed hands. So now my hands look and feel like those of a reptile :eek:

Man, I'm glad others do this, I was hesitant to admit to "squeegying" my negs. I do this as well while they are wet, straight out of the Photoflo before hanging to dry. Not something you'd teach to new processing chums, but something I have been doing for years.

It's a bit like playing a violin. Requires exquisite control. :)

I did it for many years but now seem to be blessed with dust free luck. I remove excess water by holding both ends of the film and 'snapping' it so that inertia removed water droplets that otherwise may dry and leave drying marks. Hang up in old electric clothes drying cabinet with door partially open as temperature control.

Rocket Blower (big one), Antistaticum cloth from Ilford, Antistatic and lint-free gloves. Wipe off dust with a moist cloth in the area where I handle the negatives prior to taking them out of their sleeves.

After I got rid of my flatbed scanner and got a dedicated film scanner 90% of my dust problems disappeared. Do note that I had the Epson V850 flatbed however, with it's ridiculous holders with AN-glass inserts. Not really glass, but plexi-glass, which is one of the most statically charged materials available. The people at Epson that decided to use Plexi glass as inserts for a film holder should be thrown into the open sea and left there. The most stupid idea ever.
