    A few years ago when we were digitizing 35mm images as a trial for study purposes for several courses, we also tried digitizing some of the lantern slides on the AGFA Studioscan IISi flatbed scanner with transparency attachment. They scanned beautifully. The "lanterns" that had changed to that special shade of magenta, were scanned as a gray scale and sharpened a bit.

    So we are hanging on to all our old lanterns and looking forward to incorporating them into the active teaching collection again when the structure for teaching with the digital images is built in our college.

    One big hurdle is the identification tags have fallen off many lanterns. This too we will overcome.
