Scanning

Please scan only paper in the lab. 3D objects like keys and coins scratch the glass and prevent others from making high-quality scans. Thanks!

Slide Scanner is Back


Our slide scanner is back from the shop, and is now clean, functional, and ready for you to start scanning slides again!

Slide Scanner getting cleaned

We've sent our Nikon slide scanner off to be serviced and cleaned. We're not sure exactly when it will be back, but I'm hoping it will be back in the next two weeks or so by mid-June. Sorry for any inconvenience its absence may cause, but it's all being done in the name of cleaner, crisper images, so it'll be worth the wait!

Digital ICE

Digital ICE is a technology which works specifically with transparent and semi-transparent materials like photographic film. It fairly reliably reduces or eliminates dust, scratches, and dirt that would be otherwise visible in a scanned image, without loss of quality of the underlying image. It uses a combination of hardware and software, so it's generally integrated into a slide or transparency scanner, much like the one we use here in the lab. It's not something you can simply download for your existing scanner. Also, because of the way it works, it does not have an effect on scans of opaque objects like photographic prints.

Here's a real-life example:


This is a crop from a scan of a slide taken in the 1960s. On the left, you can see all of the dirt, mold, dust, etc. that has accumulated on the surface of the film. This would be nearly impossible--or ridiculously time-consuming at the very least--to clean up in Photoshop. But the right-hand image shows you that turning on Digital ICE cleans up the dirt almost magically.

There are a couple of small drawbacks to Digital ICE. The first is that it slows down the scanning process. The second is that you will notice a slight decrease in sharpness, but nothing that can't be easily rectified in Photoshop with unsharp mask.

You can turn Digital ICE on in Nikon Scan before you start scanning slides. Ask the lab consultant on duty if you need help.

The Acetate Connection

Scrrraaaaattttcchhhhhhh! That's the sound of car keys on the scanner. If you're scanning anything other than books, magazines, or other paper products, please be extra careful with the scanner. Ask the lab consultant on duty for a piece of clear acetate (ok, technically it's "Dura-lar, the acetate alternative") to put down under the items you're scanning--like car keys, candy, paper clips, your hands and face, pens and pencils, iPods, scissors, staplers, and so forth--so we can keep the scanner glass clean and scratch-free.

Sheet Feeder Broken


Alas, the sheet feeder on our scanner is broken. kaput. dead. gone. 6 feet under. This is an ex-sheet feeder. (or maybe it's just pining for the fjords.) When you try to use it, either it doesn't feed the paper, or it actually chews the paper up. We've tried everything but have finally given up. The manufacturer's website (I still can't believe this) actually recommends hitting the scanner to fix this problem. And we did hit it. Several times, in fact, before we even knew we were supposed to. :) Anyhoo...

The flatbed part of the scanner still works fine. We're working on replacing the sheet feeder functionality with a dedicated sheet-fed scanner, which will hopefully be much faster than the one we've had all along.

Update: Thanks to Pat Heller for the following information:
