How to get dust off film for scanning.

From: Eric Stevens on 6 Jun 2010 00:13 For my sins I have recently been attempting to use my Epson V700 scanner to digitize some 35mm Fuji negatives. I find that no matter how I try I cannot get rid of dust. The best examples are barely tolerable and the worst look like a blizzard. I've been using various combinations of brush, bellow and conductive cloth but nothing seems to work. In fact, I think my efforts are making things worse for me by building up an electrostatic charge on everything around me. Its not that the atmosphere is dry at the moment. We are just seeing the last of a tropical depression and the humidity has dropped to 60%. What am I doing wrong or, better still, what should I be doing right? Thanks in advance to all and sundry.

It's been some years since I did much slide scanning. I found that even with relatively clean slides, it took me 30 seconds or even more to remove the couple of flecks of dust from each slide. It's faster to clone out a few specs in Photoshop than to go back and do a re-scan. There is no easy solution - though if you have many slides, it may be worth buying a scanner, such as a Nikon with ICE technology, which uses a separate IR beam to detect, and remove the dust. If your budget is limited (whose isn't), buy a used scanner on eBay, and sell it again when you're done. -- Mike Russell - http://www.curvemeister.com

At least at one time you could buy static brushes with a small bit of radioactive isotope built in (electroplated polonium, as I recall). The radioactivity was weak but sufficient to discharge static electricity at very close range, so as you passed the brush over the film, the isotope discharged any static build-up, making it easier to remove the dust for good. I don't know if these are still sold. People tend to be more fearful now than they once were, so perhaps not (although there was nothing dangerous about these brushes unless you broke the isotope out of the brush and ate it, and perhaps not even then).

Its dirt and dust years of poor handling and storage |
