【"You need to collect some of the pictures you usually see, and do a good job of finishing the material to ensure you can use it immediately." "" Background eraser. Take a look at the background eraser. cursor, there is a "+" coordinate in the middle of the cursor, when the "+" cursor position in the position to erase, you can rub a better effect. In other words, it means the "+" cursor is the sampled anchor point, a color with similar color tolerances is erased when the sampled anchor points determine the color of the sample. (If your cursor is not the case, execute the Ctrl+k, in the Preferences dialog, in the "Display and cursor" tab in the Settings)

Speaking of the cursor, we're going to start talking about the three sampling methods of the background eraser. There are three ways of sampling, continuous, one time, and background color plate. These three kinds of ways have their own very unusual function. Here we introduce.

Continuous:the "+" Word cursor center constantly moving, will also be the sampling point of continuous changes, the effect of the erase is more continuous.

once:"+" Word cursor center Click the mouse color sampling, at this time do not release the mouse button, you can easily erase the sampled color, do not worry about the "+" Word Center will run to the screen elsewhere. To sample other colors just release the mouse and press the mouse to repeat the above actions.

background swatches:the "+" cursor does not work at this time, the background eraser tool only to the background color and tolerance of the color similar to erase.

Select the throttling mode for the erase. " discontinuous" erases the sample color that appears anywhere in the painting; " continuous " erases areas that contain sample colors and are connected to each other; the find Edge erases the connection area that contains the sample color, while better preserving the sharpness of the shape's edges. In fact, these three kinds of restrictions are not obvious, it is recommended to use the "discontinuous" option.

The last option is very important, and sometimes when you erase the background, the edge noise left is more serious, as shown in:

If you use the Background eraser tool again to remove these edges, it is easy to erase the image you do not want to erase, especially when using " continuous " and " One time " sampling, it is easy to rub the image that you do not want to erase. Use the Eyedropper tool to set the color of the image you don't want to erase to the foreground, so check the "protect foreground" option so you don't get to the point where you don't want to erase it.
