Step 1
Select the layer on which you want to work. The layer must contain the elements you wish to alter with the magic eraser tool.
-
Step 2
Choose the magic eraser option from the tools menu found on the left side of the screen. This tool is grouped with the basic eraser tool. Press and hold the eraser tool to access the the magic eraser.
-
Step 3
Look at the options bar for choices concerning the magic eraser. You must select a tolerance value for the magic eraser tool. A low tolerance value will erase pixels that are very similar in color value to the pixel on which you first click. A high tolerance value will erase a wide range of pixels.
-
Step 4
Choose the opacity for the magic eraser tool. Opacity in Photoshop refers to the amount of transparency a layer has. An opacity of 100 percent will erase pixels completely. A lower opacity will create a partially transparent effect.
-
Step 5
Select the anti-aliased option to create a smoother edge when pixels are erased. Using anti-aliased helps avoid creating unwanted jagged edges.
-
Step 6
Select continuous to erase only pixels that fall within the tolerance value you specify and that are adjacent to each other. This erases continuous areas of pixels. Deselect this option if you want the magic eraser to erase all pixels that fall within the tolerance value anywhere in the image.
-
Step 7
Position the cursor and click to erase pixels that fall within the tolerance value. The tolerance value extends or limits the pixels that are erased.
