Adjusting Resolution

As you learned in the chapters about iMovie and iDVD, resolution is an important concept to understand in digital imaging and can be just a little bit complicated because it means different things in different situations. To refresh your memory, resolution is what determines the quality of what you see on the screen—and what you see in print. You already know that your Elements images are bitmaps. A bit, in this case, is a pixel, an individual picture element. You can enlarge a piece of your image enough to take a good look at individual pixels. Figure 22.11 shows an image of flowers in various stages of enlargement up to 1600%. At that size, you can see that the image consists of little squares in different colors or shades of gray.
