Five Things You Didn't Know About Scanners

Posted Friday, July 17, 2009

Popular Photography has published a short but interesting article about scanners.

I knew a couple of the items, particularly the "scanning film is better than scanning prints" item. Indeed, I write about this in the section of my book that deals with getting old photos into iPhoto.

But the "CCD sensor is better than a Contact Image Sensor" business -- I did not know that. More research is needed. Ah. A quick detour to Wikipedia provides some brief details on Contact Image Sensors. Hmm. Seems like they're a low-cost sensor alternative that doesn't provide the same potential image quality as a CCD-based scanner.

There you have it. I try to avoid learning new things on Fridays, but sometimes it just can't be helped.
