Bringing a Cheap 24 Year Old High-End Scanner Back to Life – It’s mind blowing

It all started when we needed to scan some slides. With my Screen Cezanne 5000 scanner I would get an amazing quality, but it would be exhausting to do. I have an old Epson scanner that could do it, but it’s also not a very comfortable task. So I had an eye on a Agfa Duoscan Hid scanner. These scanners scan film without the need of a glass. That makes things much easier. They are also great flatbed scanners. With that I take more care about my valuable Screen scanner. The lamps of it are not longer available, when they break its over. But as always it was more difficult to get this scanner up an running than I thought. It needed lots of cleaning and my first idea about a fitting computer was also not my best one.

The Scenic Mobile 800 was ahead of its time back then, but now to slow to work as a scan server.

Overhead projectors are obsolete since a long time, but back then it was amazing what that laptop could do.

Scanning without the need of glas – a great benefit of this scanner.

The scanner was very dirty and in the need of many cleanings. I cleaned it 4 times until it worked as expected. Whenever you open the scanner, you must be very careful. First of all disconnect power and SCSI. The Manual mentions also high voltage inside the scanner, I guess they’re mean capacitors or something like that. I already tried to clean the “bottom scanner” that takes care of the film scanning. I could barley see it with a little mirror, but not reach it. And dismounting the main scan unit was way too risky. I think I would never get the scanner calibrated again.

I was very happy for the SilverFast support. I had some issues, that were very specific to my configuration. Also the software is great for scanning film. Check out their website here : https://www.silverfast.com

This scan of one of my moste favourite portraits (Phoebe) was done with the Screen Cezanne and is very similar to the Agfa, see the video for more details

Preserving History – Renovating a 100 Year Old Camera – Bellow Edition

My good old Century No.2 camera has about 100 years behind her. She still works great, but her bellow is leaking light. Thats why I needed to repair it. I thought it is easiest to explain everything in a video, so it is easier to understand for you guys and hopefully also helpful. It took me a long time to put everything together. Why? Because it was important for me to reuse as many original parts as possible to preserve the history of this camera. I think this is a very important part when you consider to renovate a piece of history! Underneath the video are all links for the parts I needed.
