A photographer needs a green or blue shaded cloth for placing it as the background of the subject.

Use flood lights that are covered with a butterfly sheet as these illuminate a subject properly and eliminate all sorts of shadow areas on the face or clothes of the subject. These flood lights also leave a soft effect or touch on the face of a person and this enhances the perfection of photography.

Perform the masking process by selecting any image and replace it behind the subject. You can make a person place behind Seven Wonders of the World' or place him in an exotic and exquisite locale.
