PICTURE IN A PICTURE
Picture in a picture includes three separate techniques. The first type, shown in the first three photos, was done by taking a photo in which a photo from the past is in front of the current location to show passed time.
The next part was to digitally manipulate a photo. It was done by taking a photo containing a frame and replacing the contents of the frame with the original photo.
The third part was to take a picture with an empty frame, showing something that could realistically be shown in a frame. I edited the outside so it was black & white to show contrast.
