Blend Range Transparency

The transparency of an object or group of objects can be set using color ranges from the image of the object. This transparency mode is suitable for image objects that may contain some background tone regions.

With the blend range transparency mode, the mask is created from the object and the backdrop images using a tone adjustment function.
