Ion Audio's Slides2PC Digitizes Your Old Negatives Simply, For $100 Devices to digitize your old photo collections aren't new , but Ion Audio's new Slides2PC makes it about as simple and cheap as you might imagine. It takes a sled full of 35mm film negatives or slides, and turns them into 5-megapixel image files at the push of a button, with auto exposure control and color correction. So it's no pro-resolution image-cruncher, but 5-megapixels is perfectly serviceable—especially when the USB-connecting gizmo costs just $100. [Everything USB ]
