Chapter 15. Creating and Editing Digital... > Understanding Image Resolution

Understanding Image Resolution

One of the most important concepts that you need to understand when working with digital images is the resolution with which that image is captured or created and the resolution at which that image will be displayed or used. The resolution of the images that you use is critical to their quality and suitability to the purposes that you have in mind.

The Fundamentals of Resolution

Resolution can be a difficult topic to grasp because the same term is used in different contexts. To understand the resolution that you are working with, you need to understand the area you are in (for example, on the desktop versus working with a printer). Differences in resolution on different devices (scanners, cameras, printers, monitors, and even on different operating systems) greatly impacts how specific images look on those devices.
