For accessing brush options, you need to right-click at a suitable point on an image.
Brush hardness should be more as soft edges may not be successful in erasing color completely. Choose adequate brush size. Spacing should be less. This will enable smooth erasure of line.
You may select ‘Sampling Once’ option from the top panel for sampling color once and erasing a large section of an image. Choose ‘Contiguous’ as Limit and ‘50%’ as Tolerance.
3) Use The Tool For Erasing Background
Choose an appropriate part of an image. Click and keep the left mouse button pressed. Start dragging the mouse around for erasing.
If you want to erase something that is not adjacent to present area, go to ‘Limits’ option and change ‘Contiguous’ to ‘Discontiguous’. This will allow you to delete photo background area that is not adjacent or is isolated.
4) Exercise Other Options
It is possible that the background color closely resembles the subject’s color. To avoid erasure of color from the subject, you need to keep the Tolerance level low.
In contrast, you should keep the tolerance level higher if the background and subject colors differ significantly.
You can also exercise ‘Protect Foreground Color’ option if background eraser is causing foreground color to fade. You can sample the foreground color by holding Alt/Opt to direct Photoshop not to erase the same with Background Eraser.
5) Erase Different Hues Of Background Colors
Once you use the tool to remove background from image for one color, you may find that some shades and tones of other colors are still present. To get around this, go about sampling a new color and carry out the process from start. Selecting ‘Sampling Continuous’ option from the top panel would also help.
However, you must exercise caution else you can accidentally erase image portions, which you wanted to retain, by wrongly sampling subject’s color. Use mouse crosshair for aiming at a different color and keep repeating the process until the image gets completely cleared of distractions.
