Chapter 13: Sizing and Transforming Images

Overview

Photoshop documents can be resized and transformed in several ways. An image can be enlarged by adding new solid-colored pixels or reduced by cropping out unwanted areas from its edges. An image can also be made smaller or larger by resampling. When you reduce the size of an image in this way, you discard pixels from the image content. When you resample to enlarge an image, you add new pixels. All of these operations can significantly affect the look of the final published work. This chapter will examine issues related to image size and will help you best determine the methods to choose when capturing, sizing, and transforming an image to achieve optimal results.

This chapter will help you understand:
