The stroke border is not only an easy way to jazz up a common snapshot for a scrapbook, but in Adobe Photoshop CS4 the stroke border can go far beyond a simple frame for your photo. With a little experimentation--such as creating stroke borders and outlines around separate objects or around multiple objects in one photo, or employing varying colors as well as dynamic visual effects--borders can become quite elaborate, thereby making images pop out in virtual depth.
Simple Stroke Border
To add a stroke border to an image, select the menu item "Select" and click on "Select All" ("Ctrl+A").
Click on the "Edit" menu item and select "Edit" and click on "Stroke..."
In the "Edit" pop-up box that appears, create the stroke border by specifying your chosen attributes. Click "OK."
To adjust the size of the stroke, position, blend and fill type, repeat steps 2 and 3, and set the values in the "Stroke" pop-up box.
Stroke Border in Layers
Select the layered object in the "Layers" tab to apply a stroke border (click on the object and highlight it).
Click on the "Layer" menu and choose "Layer" and select "Layer Style" and click on "Stroke..."
In the "Layer Style" pop-up box that appears, select the check box for "Stroke."
Adjust the size of the stroke, position, blend and fill type by setting the applicable values. Click "OK." The layer will retain your selections, and may be edited and modified at any time, as long as the layer is not flattened. To make changes to the stroke style, repeat steps 1 through 4.
The layer styles can be cleared, as well as copied and pasted to other layers or images. Explore the "Layers" tools and experiment and have fun. Layers are one of the most powerful tools in Photoshop.
