An informal walk through of how I mount two sheets of 4x5inch negative film onto a scanning drum designed for the Howtek Scanmaster 4500.

  • why do you use mylar while KAMI fluid dries rather quickly and thus eliminates the spilling problem.

  • @zhengjdc The mylar is required to hold the film in place so it doesn't fly off the drum when it starts spinning. Furthermore, without the mylar in place the KAMI fluid would dry within seconds and after it dries it will no longer effectively displace air to prevent Newton rings and maintain contrast.

  • Are you (and jamesrosssmith) members of the Yahoo high end scanner user group? There has been some discussion about using other fluids . . . some of which aren't even specifically designed for drum scanning. Clean up may become more problematic though.

    For lower resolution scans there are some mounting powders that you can use but at even 300DPI and up you'll start to see the powder. Without mounting fluid contrast seems extremely low and every flaw on the drum shows up.

  • I noticed that you use FILM cleaner to "polish" the mylar overlay. I'd recommend NOT doing this, as the drums are very susceptible to solvents and such. The film cleaner will attack your drum's surface, causing hazing or worse, crazing(microfractures). I've also seen drums become "sticky" due to using bad chemicals(like Windex, NEVER USE WINDEX) to clean/"polish" their drums.... BAAAAAD idea...

  • @jamesrosssmith we always used Liquid paraffin to 'oil' transparencies, available cheaply from Chemist / Pharmacists - you will get a funny look as its prescribed for constipation. Worked a treat for our award winning scanning back in the day!

  • @Klyment

    Well, with good sealing technique, I had sealed film successfully without mylar and the fluid stay underneath of the film for the entire scanning process.

  • ...same problem here. Is it possible to scan dry mounted neg/pos with success?

  • Great video. It's almost impossible to get Kami fluid here in Australia :(

  • yeah you shammy that film. shammy it good.
