Two ways to cut objects out from the rest of the image.
Use the Cut tool to draw a shape around the object you would like to cut out and just release the mouse button or touch the starting point to close the path. Alternatively you can start cutting click by click to get a more precise cutout. Either way you can fine tune the shape by moving the control points even after the path is closed.
Use the Feather slider to smoothly blend it in.
With the feathering feature you can merge images seamlessly together, just like it was supposed to be there. The slider appears after the image has been cut. Digital compositing has never been so simple. Unleash your visual effects artist within.
