You may want to eliminate the white background from a photo mainly because of two reasons. First, you may want to create a composite for which you need a cutout and second, you are looking for a transparent form of your logo. Fortunately, Photoshop comes equipped with a lot of features that would allow you to delete white background or any other type of background easily. What you should know is that the overall image quality and color will depend on the tools and techniques that you use to perform this edit. You can use The Magic Eraser or Background Eraser tool if the image that you wish to edit has only dark colors and no light colors. If you have to edit an image that has an elaborate background or lighter shades, you should opt for an advanced tool so that you don’t end up deleting important details by mistake.
In this article, we have given tutorials on how you can remove the background of an image using three Photoshop tools namely, the Magic Eraser tool, the Quick Selection tool, and the Background Eraser tool. What you should know is that transparency is denoted by grey and white checkered grid. So whenever you spot this grid, it would indicate a transparent grid.
Using this tool is quite easy, just focus on the following steps and you would be able to get desired outcomes:
The first 2 steps remain the same for the Background Eraser and the Magic Eraser tools. So begin by following the same first 2 steps.
Click on the Background Eraser tool to select it.
Go to the Eraser tab to spot this tool. The tool cursor bears crosshairs at its central portion and appears like a circle. You need to use these crosshairs properly in order to use the tool. These crosshairs selects the color that lies directly underneath. In the present case, these will sample the white background. Selecting appropriate preferences is the key to getting desired results. If we have to delete a white portion that lies just behind a vibrant portion, we should ideally select the size to be between 300-800 pt., a tolerance of 20 percent, ‘Find Edges’ as limits, and Once as the sampling option. You should also select “Protect Background Color” as a preference. The black color should in the foreground below the toolbar.
Deletion of the white background
Click the mouse button after putting the cursor on the white section. Continue to push the button and pull the cursor over the white section. We chose the 20 percent tolerance, so other colors would not get affected. If we choose a higher tolerance value, the other colors would get impacted to a small extent. You may want to opt for different tolerance values for different images. If a few white pixels remain, you can use the normal eraser to wipe them off.
The last 2 steps from the Magic Eraser tool should be followed now.
If a white background appears cloudy or has dark edges, you would need a different tool over which you can exercise a greater degree of control. The Quick Selection tool is one such tool.
