Inverting and removing masks
You can invert a mask so that the protected area becomes editable and the editable area becomes protected. Inverting a mask when defining the image area that you want to protect is easier than defining the area that you want to edit. For example, if you want to edit an intricate shape in an image that is set against a plain background, it is easier to select the background and then invert the mask.
You can remove a mask from an image when you no longer need it.
First, the background was selected (left); then, the mask was inverted to define the orange bottle as an editable area (right).
