1. An image-processing workstation, comprising a computer processor, a memory coupled to the processor, and a computer-readable hardware storage device coupled to the processor, the storage device containing an image-processing application configured to be run by the processor via the memory to implement a method for using imported depth information to mask or select areas of a first digital image comprising a first set of pixels that are each associated with a corresponding set of graphical properties, the method comprising: the image-processing workstation receiving the first digital image, wherein a depth map is embedded into the first digital image as metadata, wherein the depth map comprises a first set of depth values, and wherein a first pixel of the first set of pixels is further associated with a first depth value of the first set of depth values; the image-processing workstation accepting a command to identify a first subset of the first set of pixels; the image-processing workstation, in response to the command, identifying a boundary of the first subset, wherein the boundary comprises a second subset of the first set of pixels, and wherein the identifying the second subset is performed as a function of the depth map.
