1. Open a Photo in Photoshop
First, open your image in Photoshop and look at the layers panel. If for some reason you don’t have this panel, then you need to turn it on/off by pressing the F7 key or going Window > Layers. There should be one layer there; the program defines it as the Background. There is a lock icon on the right of the layer. It means that the layer is locked for editing and currently you can’t remove background from an image.
2. Select the Background Eraser Tool
By default, the Background Eraser is located behind the Eraser Tool. To activate it, right-click (Win) or Control-click (Mac) on the Eraser Tool > choose the Background Eraser Tool from the drop-down menu.
3. Select a Hard Round Brush
You need to choose the same settings as shown in the screenshot below. At this stage, you need a Hard Round Brush. The Background Eraser Tool is actually a brush, and like the other Brush tools in Photoshop, you can adjust its size right from your keyboard. Press the left square bracket key “[“ several times to make it smaller, or the right bracket key “]” to make it larger.
You can also adjust the hardness of the edges by pressing a Shift key. Press Shift + left square bracket “[“ several times to make the edges softer, or Shift + right square bracket “]” to achieve the opposite effect.
4. Configure Background Eraser Tool Settings
The parameter that largely affects the success of Photoshop deleting background process is the Limits of the Background Eraser. When the program grasps which color you want to get rid of, Limits gives the cue of where to look for appropriate pixels. While altering Limits, you can choose Contiguous, Discontiguous or Find Edges modes. I recommend selecting “Find Edges”.
You also need to adjust Tolerance, which “tells” how much a pixel’s color differs from the sampled color not to confuse Adobe Photoshop. By default, this value is set to 50%, but you need to go as low as 25%.
5. Proceed with Background Removal
Now you can increase the size of the Eraser and start deleting the background in Photoshop. Don’t restrict your movements, as the tool won’t erase your main object, but will work only with the background. Your background will be painted over with a checkerboard, which denotes a transparent background. You can place the object on another background that suits you or leave it on a transparent one.
6. Done! Save the File
Once you are done removing the background, take a closer look at the result to make sure there are no unnecessary parts of the background left. Export the image as a PNG file. Click File → Export → Quick Export to PNG. If you save it as JPEG, all our hard work will go in vain, as the picture will be saved with a white background. JPEG doesn’t support transparency.
Be careful! While deleting the background in Photoshop, you simultaneously remove the shadows that the object cast. That’s why it is a good idea to learn how to add drop shadow in Photoshop. The process boils down to 8 simple steps but guarantees realistic results.
