| I have been gathering some information on a type of polarizing filter which is used to "tint" the windows on private jets. From what I understand so far, this unit consists of a remotely controlled polarization sheet of material, controlled by a small touch pad . Sounds interesting, especially if the size of the filter itsself would be such that use on the platten a flatbed scanner would be possible. The ability to control the polarization remotely would eliminate the need to shift the position of the photo being scanned and allow for fairly rapid corrections. When I get a reply back from the company making these , if it looks like a useful tool, I'll post what info I have, Right now everything is a little hazy, fact wise. Tom |
