When you open a picture in Photoshop Elements, you’re looking at a huge mass of pixels. These pixels are tiny, colored squares, and the number of pixels in a picture determines the picture’s resolution. This relationship between pixels and resolution — important to understand in all your Elements work — relates to creating selections (as we explain in Book IV, Chapters 1 and 2), printing files (Book IX, Chapter 2), and sharing files (Book IX, Chapter 3).

This chapter explains some essential points about resolution and image sizes and displaying images onscreen, especially in terms of the way these points affect how you end up modifying your images.
