- Removing background With the Polygonal Lasso Tool.
Another elite tool to remove the background around the image is the Polygonal Lasso Tool. This can particularly be useful when you have a moderately complex item like a bird on a branch, for instance.
We will start out by duplicating the background layer so you have something to go by as you work. If we recall from our previous tutorial, the shortcut Ctrl+J (Cmd+J on Mac Os) was used in duplicating a layer. This can also be done by right-clicking on the layer and selecting “Duplicate Layer” The lasso tool is designed for working with images with complex edges set against a contrast color. When using the lasso tool, you’re free to choose the area you want to keep (the bird and the branch). Then by using the move tool, you can move your chosen area and the background remains empty. When you have moved the image to where you¬¬ want it to be located, you can then add other colors as needed to enhance the image or use the colors that make the image more unique. Another option is to select the lasso tool in the tools panel, select the Polygonal Lasso Tool, and then pick a spot on the image to connect the lasso.
Then you just carefully pull the “string” out along the surface and edges of the image, and work your way around the entire image, making sure the layer named “Background Copy” is selected in the layers panel.
Then you choose the refine edge box.
Select a 1 for smooth, 0.8 for feather, and +4 for contrast, select “layer mask” from “output to” and then click on Ok. (You can play around with these settings to experiment more) Go to the right hand side of the page, by clicking on the little eye icon beside the layer thumbnail, and the background disappears. You can now add a new background by Placing or Filling (as in previous tutorial).
Your result should look like this… or somewhat.
..and we’re done!
