One of the easiest and least expensive ways to get rid of a bad background or deleted piece of background in an image in Adobe Photoshop is to use the Background Eraser Tool. This tool works as a combination of the eraser and the Quick Selection tools, working together. The Background Eraser Tool uses the current color as the center of its brush and removes pixels on a pixel by pixel basis. The image will remain, so the effect is a brush stroke with very fine detail. You can use it to remove anything from a bright red apple to faded images of children.
There are a couple of methods you can use to erase an image. You can just use a single brush stroke to erase a certain area in the image or you can use the eraser and use a different brush stroke to erase smaller areas. If you use the eraser with the Brush Selection Tool, this allows you to select the color in a stroke, erase that color using another stroke, then erase the next color using another stroke until all the colors are erased. However, this technique will only work with images that have color in their background. If the background is black and white, the eraser will only work with a solid color brush. To erase any area of your image, you should use the Paint Bucket Tool, the Fill-In Tool, or the Stroke Path Tool.
Background erasers can be used to clean up a lot of mess in your pictures. The trick to using the eraser in your image editing software is that you must keep using it until you are satisfied with the way it has cleaned up the background. You should also try to be as subtle as possible with your background, because your eraser will cause the background to be outlined and will not be subtle at all. If you use a small brush stroke when you erase an area of your background, it will look cleaner. When you erase a large brush stroke, it will be harder to maintain the image. Once you are satisfied, click on the "Auto Erase" option, then you are ready to preview the image. and then print it.
