photoshop lasso tool
Both the rectangular and elliptical marquee tools can make selections, and the selections they make are regular. It is difficult to pick out irregular shapes, so we will think of the three tools in the Lasso tool group.
The first lasso tool in the lasso tool group is used to make arbitrary irregular selections, the polygonal lasso tool in the lasso tool group is used to make certain regular selections, and the magnetic lasso tool in the lasso tool group It is a selection for making pictures with clear edges and a large color difference from the background. And pay attention to the settings of its property bar when using it.

1. Settings for selection addition and subtraction: When making selections, the "New Selection" command is used more frequently.
2. “Feather” option: The value range is between 0-250, which can feather the edge of the selected area. The larger the value, the larger the feathered edge.
3. The function of “anti-aliasing” is to make the selected area smoother.
4. The value range of "width" is between 1-256. You can set a pixel width, and the generally used default value is 10.
5. The value range of "Edge Contrast" is between 1-100. It can set the sensitivity of the "Magnetic Lasso" tool to detect edge images. If the color contrast between the selected image and surrounding images is strong, then a higher percentage value should be set. Otherwise, enter a lower percentage value.
6. The value range of "Frequency" is 0-100. It is an option used to set the rate at which key points are created when selecting. The larger the value, the faster the speed and the more key points there are. When the edge of the graph is more complex, more key points are needed to determine the accuracy of the edge. A larger frequency value can be used, and the default value of 57 is generally used.
When in use, you can control key points through the backspace key or the "Delete" key.
