Eraser Tool

                 Eraser Tool deletes the object on the selected layer and makes it look transparent, i.e.,
                 the background layer’s object can be seen. You can change/toggle with the preferences in
                 the Options bar for Eraser Tool. Set your brush size and the mode that you want to use.
                 You can choose from Brush, Pencil, or Block options. To change the transparency of the

                 object, use the Opacity slider. Flow option helps you to determine how quickly the eraser
                 is applied.

                  Background Eraser Tool

                 To remove a background or part of a background from an image in Photoshop, we use the
                 Background Eraser Tool. This tool is a combination of the Quick Selection Tool and the
                 Eraser Tool. Background eraser means erasing the background without erasing the main                     117
                 object. It is therefore very tricky and requires more than just an eraser. It samples the

                 color at the centre of the brush and deletes pixels of the similar colour when you drag the
                 tool around your image.

                 Follow the given steps to use the Background Eraser Tool:
                 Step 1:  Select the Background Eraser Tool from the Tools panel.

                 Step 2:  In the Options bar, pick a brush size according to the image, set the Sampling to
                          Continuous, the Limits to Find Edges and the Tolerance to low. A low tolerance
                          means that only areas that are very similar to the sampled color will be erased. A
                          high tolerance erases a broader range of colours.

                 Step 3:  Bring the mouse pointer near the edge of the object from which you want to remove

                          the background. You will see a circle with small + sign (cross hair) in the centre.
                 Step 4:  Click and drag to start erasing. Do not drag the cross hair over the edges. As you
                          click and drag, you will see a checkerboard pattern appearing in the areas you have
                          erased. That is the background of your canvas.

                 Step 5:  Once you have erased around the entire
                          object, you can switch to the  regular
                          Eraser Tool for any final adjustments.

                 Step 6:  Choose a large brush size and erase the
                          rest of the background.
                          Though  this tool  does not erase  with                  Using Background Eraser Tool
                          perfection around the edges, it is the quickest way to distinguish the background
                          and the main object.
