Digital pictures consist of dots called pixels. Enlarging a picture makes these pixels bigger and reduces the resolution. It is common to take pictures at low resolutions, such as 72 dpi, but such pictures will end up looking blurry when enlarged. If you want a quality picture that you can print, it must be at a resolution of at least 200 dpi (dots-per-inch). You can attain this by setting your camera to take pictures at its highest resolution. Resize your picture, free, with Paint, a program already on most computers, or use a photo-editing application, like Photoshop, for more options and professional results.
