Section 1: Creating Selections In the process of image editing, you may encounter situations where local adjustments are needed. In such cases, using selections to define a specific area of an image before performing edits is an effective method. Below we will detail the basic operations for creating selections in Photoshop CS3.
I. Standard Selection Tools Standard selection tools can create regular, simple-shaped selection areas within images. The main standard selection tools include four types: Rectangular Marquee Tool, Elliptical Marquee Tool, Single Row Marquee Tool, and Single Column Marquee Tool; detailed descriptions follow.
- Rectangular Marquee Tool The Rectangular Marquee Tool allows you to create rectangular or square selections in your image easily by clicking on the 'Rectangular Marquee Tool' button in the toolbox (as shown in Figure 2.1.1). Click and drag while holding down the left mouse button to create a dashed border rectangular selection. Figure 2.1.1 shows the properties bar for the Rectangular Marquee Tool. By clicking on this button, a reset tool panel appears as shown in Figure 2.1.2. In this panel's upper right corner is a menu that includes commands like 'Reset Tool' which restores current tool settings to default values; 'Reset All Tools' resets all toolbox tools back to their defaults...
