Task 3 How to Erase a Background

Photoshop offers two ways to erase a background: the Background Eraser and the Magic Eraser. This task looks at how to use both tools, highlighting the differences between them. The Background Eraser erases an image area selectively, based on a pixel's value. It remembers the first pixel value you click and then erases only that value, ignoring other values. This initial value is referred to as a sample point because the value of the pixel is used as a sample to determine how the eraser interacts with the image. You use the Tolerance slider to determine whether the brush erases the exact value sampled or a range of values based on the sample.

1. Select Background Eraser

With the image you want to modify open onscreen, select the Background Eraser from the toolbox. If necessary, click and hold the active Eraser tool and drag to select the Background Eraser from the pop-out menu that appears.
