More About Resizing ... and InterpolationResizing an image - especially if you're making it larger (which is usually the case) - involves rearranging the data (pixels) in your image. And making an image larger than it's original size and resolution involves a process called "Interpolation." There was a time when Interpolation was frowned on, and for good reason. It didn't work well at all, and images rapidly deteriorated to the point where they were just downright ugly (big nasty pixels, "digital noise" and ghostly artifacts). But the technology has gotten much, much better over the past couple of years. So, while you still need to be watchful, don't be afraid to "Interpolate." Simply put, all the software is doing when you interpolate an image is adding pixels to existing pixels using some kind of magic (I truly DO NOT understand how this is possible!). As I understand it, the added pixels are made to resemble the original ones, and blend colors together in such a way that they are virtually indistinguishable. In any case, try it. Your mileage may vary. But I've had outstanding results - even when interpolating an image up from it's original (10.026x6.66 inches @ 300 dpi) size to a whopping 20x30 inches.
