If you check the “Contiguous” checkbox, you only erase pixels touching the pixel color you select. To make the erased selection have smooth, versus jagged, edges, then check the “Anti-aliasing” checkbox. A lower opacity only partially erases the pixels. A 100% opacity completely erases all the selected pixels. Then use the “Opacity” slider to adjust the opacity of the erased pixels. A higher tolerance erases pixels with a broader range of color similarity. A low tolerance erases only pixels with a color very similar to the one you select. In the Tool Options Bar, you can also use the “Tolerance” slider to define the range of colors similar to the one to remove. It shares a spot in the Toolbox with the Eraser Tool. Make sure to also select it within the Tool Options Bar, if needed. To use the Magic Eraser Tool in Photoshop Elements, select it from the Toolbox. You can use this tool to only erase contiguous (touching) pixels or all pixels that are similar in color. Otherwise, the pixels will be erased to transparency. If you use this tool in the background layer or in a layer with locked transparency where you cannot edit the transparent pixels, the pixels will change to the background color. You can use the Magic Eraser Tool in Photoshop Elements to change similar pixels throughout an image.
