A photographing device is provided, including a photographing unit, an image processor which separates an object from a first photographing image obtained by the photographing unit, a display which displays background live view on which the separated object is superimposed, and a controller which obtains a second photographing image corresponding to the background live view when a command to shoot a background is input, and generates a composite image by adding the separated object onto the second photographing image. Accordingly, a composite image may be easily generated.
