Level 3

Lesson 3

In this lesson, you will learn how to view an image at different zoom levels.

Introduction

In the course of editing an image, you will always need to magnify part of an image to work on small details, reduce the view size to see the entire image, or view the image at actual pixel size.

The following lesson will show you how to view an image at different zoom levels, and give you some information about the status bar displays.

·   Open a file approximately 1MB in size.

·   Rest the pointer on the lower right corner of the document window. The pointer will change to a double arrow.

·   Hold down the mouse button and drag the corner diagonally downward to enlarge the document window.

As you enlarge the document window, some numbers will appear at the bottom border of the window.

The area where the numbers are displayed is called the “Status bar”.

The percentage on the left side of the Status bar represents the zoom level of the active image.

·   Click the small triangle on the right hand side of the Status bar.

·   Choose Show > Document Sizes.

With Document Sizes chosen, the number before the slash on the right side of the Status bar represents the file size of the active image. The number after the slash indicates the file’s approximate size, including layers and channels.

Since this image is flattened, with no channels and contains only a background; the numbers before and after the slash are the same.

From the “Toolbox”:

·   Look for the “Annotation, Measuring, and Navigation Tools”.

·   Select the [ Zoom ] tool.

·   Position the [ Zoom ] tool over the dark magenta balloon and click once.

The image will enlarge to the next preset percentage level, which is 100%.

·   Click on the dark magenta balloon again with the [Zoom ] tool.

The image will enlarge to the next preset percentage level, which is 200%.

·   Hold down the Alt key on the keyboard so that the Zoom tool pointer appears with a minus sign (-) in the center of the magnifying glass.

·   Click on the dark magenta balloon again.

Now, the view zooms out to a lower preset magnification, which is 100%.

·   Release the Alt key.

Note: the preset increments are 50%, to 66.67%, to 100%, to 200%, to 300%, etc...

·   Draw a rectangle to enclose the clown’s head by dragging the mouse.

The image will enlarge so that the clown’s head fills the document window.

The zoom level also changes to 227.68%.

From the “Toolbox”:

·   Look for the “Annotation, Measuring, and Navigation Tools”.

·   Select the [ Hand ] tool.

·   Using the [ Hand ] tool, you can drag the mouse to pan over the image. This will allow you to find the area that you want to look at.

Conclusion

In this lesson we showed you how to navigate around the screen using the Zoom tool and the Hand tool.

You also learned how to interpret some of the information on the Status bar displays.
