Step-By-Step Instructions:
1. Open the image of the cutout object/person. Open the image of the background image.
2. Copy and paste the object/person onto the background image.
3. Select the Polygonal Selection tool.
4. Zoom in and create a polygonal selection that outlines the edges of the object/person.
5. Adjust the Radius slider so that it will slightly blur the outlined edges of the polygonal selection. Then click OK.
6. As you can see below, the edges of the object/person have been blurred a bit. This blurring of the outline helps blend the overlapping object/person with the background better.
6. You’re done! You should now have a perfectly blended object over the background layer.
