As well as double-clicking to close polygonal and magnetic selections, you can also hold down the Control key and click. The Magnetic Lasso tool can be turned into the Polygonal Lasso tool by holding down Alt/Option and clicking with the mouse where you want the straight line segments to end.Likewise, you can turn the Polygonal and Magnetic Lasso tools into the regular Lasso tool by holding down Alt/Option and dragging with the mouse.To revert to the regular Lasso, release the Alt/Option key while the mouse button is held down. You can temporarily turn the regular Lasso tool into the Polygonal Lasso tool by holding down Alt (Windows) or Option (Mac), then releasing the mouse button, then clicking where you want the end of the straight line segment to be.As well as the automatic points added by the Magnetic Lasso, you can add your own manual fastening points by clicking with the mouse.You can keep pressing Delete all the way back to the first fastening point if necessary. If you place a fastening point incorrectly with the Polygonal or Magnetic Lasso tools, press the Delete key on the keyboard to “undo” the point.When you delete the selection you should be left with just the non-white pixels on a transparent background (3): Upvote. A higher Frequency value will place more fastening points as you trace round the object. However, it is likely that you will be better off using a different tool such as the Magic Wand (1) to select all the white pixels. The Frequency option controls how often the Magnetic Lasso tool will automatically place fastening points. A high Edge Contrast value will only detect edges that contrast strongly with the rest of the image, whereas a lower value will detect softer edges. For more blurred edges, reduce the width and trace more precisely.Įdge Contrast specifies the tool’s sensitivity to the edge of the object you’re selecting. If your object has well-defined edges you can set a high “Width” value and trace the object quickly and roughly. 37.Width controls the range of pixels around the mouse pointer within which the tool looks for the edge of the object you’re tracing.Doing so allows you to easily select the area you want, no matter how many times you clear the selection. In general, as outlined in ' Use Color Fill for the Undercoat' and ' Making a Selection with the Magic Wand', it is recommended that you create an Undercoat layer and then use the Magic Wand to make selections. For example, if youre drawing a path around a bird. You could shade this with an airbrush or similar. Like the magnetic lasso, the magnetic pen helps your lines stick to any edges identified in the image. When you close the Layer window you will be able to see the dashed lines the show where the selection is. Open the Layer window and tap ① Normal Layer to toggle to the Current Layer to a normal layer. Incidentally, this is a great Photoshop prank to play on co-workers, friends, soon-to-be-enemies, etc., because the Feather field is usually the last place they. If you want to apply colors you need to change the Current Layer back to a Normal Layer. Please note that when the Current Layer is the Selection Layer it is not possible to choose colors (as there are no colors in the selection layer). The area that you have brushed over will turn a transparent blue. You can now use the brush or eraser to make a selection. Tap this layer to make it the Current Layer and then close the Layer window. The uppermost layer, with the pink background, is the ② Selection Layer. If, however, you want to make a more detailed selection you can use the selection layer.įirst, open the ① Layer window. The Magic Wand and Lasso tool are most common when making selections.
