A design technique that places a part of the picture as a frame around the main subject in order to emphasis the center of interest.
Man-Made Frames can be found all around you.
Natural Frames always look good too!
Blur other people to make the frame, and focus on the main subject.
Framing Illusion
Use Photoshop or the free Adobe Mix App for your Phone or I-pad to cut out the picture frame. Take two photos, preferably using a tripod; one photo with your subject holding a frame, and one photo just of the background. Place the background photo down first in Photoshop. Cut away the inside of the frame on the second photo to reveal this simple framing illusion.
