Chapter 11. Paper Options, Printers, and... > Working with low-resolution images

Working with low-resolution images

Perhaps you mistakenly saved over your original high-resolution file with a low-resolution version. Or, you received an image optimized for email or one downloaded from a Web site. Maybe you set your digital camera for a low-resolution setting to pack more images on your memory card. In any case, you've got a low-resolution image file that you want to print with high-resolution results. While turning a low-resolution image into a high-quality print isn't always easy (or possible), there are a series of steps you can take to evaluate your image and make adjustments to produce the best possible print.

Be wise when you resize

The first thing that comes to mind when presented with a low-resolution image for printing is to resize it to a higher resolution. This technique is called resampling, as your image-editing application literally samples the image data and re-creates that information at the new resolution. When pushed to its limits, resampling can pixelate the image, soften contrasts and transitions, and wash out colors. However, sensible resampling can produce acceptable results.
