Pepper's Ghost is a special effects technique for creating transparent ghostly images. It works by reflecting the image of a ghost off of a sheet of plexiglass. IThis effect has been a staple of theaters and haunted houses since John Pepper popularized it in the 1800s. In this project, I am going to show you how you can incorporate this technique into your Halloween setup.
Step 1: How the Illusion Works
Step 2: Create a Ghost in Your Pictures and Video
Set up your camera in front of the desired background. Position your ghost to one side of the camera. The ghost can be a person in a costume, an image on a computer monitor, or just a picture. Hold up the plexiglass in front of the lens at a 45 degree angle to both the camera and the ghost. The camera will see a faint reflection of the ghost.
You may also get reflections of other objects around your ghost. To avoid this, you can either set up your ghost in front black backdrop or you can put the ghost in a dark room and use a flashlight or lamp to light up just the ghost.
