Set Transparency Preferences in Photoshop Elements 12
Using the Transparency settings in Photoshop Elements requires an understanding of how Elements represents transparency. Imagine painting a portrait on a piece of clear acetate. The area you paint is opaque, and the area surrounding the portrait is transparent — invisible, in other words.
To display transparency in Elements, you need a method to make transparent areas visible. To accomplish that task, open the Transparency preferences and make choices for displaying transparency in your 2D Elements environment. Transparency becomes especially important when you start working with layers. The Transparency preferences are shown in the figure.
The Transparency preferences settings available to you include
Grid Size: The grid you see in the image in the upper-right corner of the Transparency preferences pane displays the default settings for the grid size and color. You can change the grid size to None, Small, Medium, or Large.
Grid Colors: From the drop-down menu, you can choose from preset colors to display the transparency.
First transparency background color: Click the swatch if you want to make a custom color choice for one set of the pattern squares.
Second transparency background color: Click the second color swatch if you’d like to choose a custom color for the second set of pattern squares.
Any changes you make in the Transparency settings are dynamically updated in the large preview in the upper right.
