The article I published yesterday on Converting My Personal Library to Digital has already generated a number of comments at the end of the article and also private email messages to me. The most common questions are:
“What are your thoughts on the best receipt scanner that I can go between iPhone, iPad and PC?”
“What is the best portable scanner for use in libraries or archives where it isn’t convenient to carry a full-sized scanner?
My answer is the same for both questions: “Your present cell phone’s camera.”
Your cell phone probably is also your cheapest solution as most people already own a cell phone with a built-in camera of rather good resolution. That wasn’t true a few years ago when the cell phone cameras were lower resolution and produced somewhat grainy images. However, most of today’s cell phones produce high-quality 8-megapixel or even higher resolution images. My new cell phone has a 12-megapixel, phase detection autofocus and laser detection autofocus camera with f/2.0 aperture. It produces gorgeous images even when used close-up to the document being scanned… uh, captured. Most other cell phones these days have similar specifications or something approaching those specs.
