Between the slides and the scanner, you're talking a lot of dust possible. --- news://freenews.netfront.net/ - complaints: news(a)netfront.net ---

My scanner is an Epson V700 which has a double lens system - one to focus on the image and the other to focus on the surface to detect dirt and scratches. The V700 comes with ICE technology.

Thanks for the suggestion. I was thinking of doing that except for the fact that today (in New Zealand) is a public holiday. Eric Stevens

I won't do it your way but I will rig up a pair of antistatic brushes designed to clean vinyl LP records. http://www.productwiki.com/carbon-fibre-record-cleaning-brush/ Second thoughts. These brushes use carbon fibres. Am I introducing a scratch problem? I don't think so. Vinyl records are likely to be vulnerable to scratch damage also. Still I will tread cautiously. Eric Stevens |
