Chapter 14: Image Capture and Digital Photography

Overview

The process of digital imaging begins when an image is captured. Two broad types of devices can be used to convert a real-world scene into digital information: the scanner and the digital camera. These devices see light and color and convert what they see into numerical information that Photoshop can use. Learning to use a digital camera or a scanner properly is an important skill, and many variables enter into producing a quality image. In addition to image size , factors such as resolution, contrast adjustments, and hardware limitations must be taken into consideration. This chapter will introduce you to the best methods for inputting your image so that you can be assured of producing the best possible results in Photoshop.
