Front projection film is designed to be viewed from the front of the screen, while rear projection film is designed to be viewed from the back. With front projection, the projector is placed in front of the screen, and the image is projected onto the film from the front. This setup is commonly used in home theaters and conference rooms. Rear projection, on the other hand, involves placing the projector behind the screen, and the image is projected onto the film from the rear. This setup is often used in large venues and outdoor events. The main difference between front and rear projection film is the direction of the projection. Front projection is suitable for smaller spaces with controlled lighting, while rear projection offers better visibility in areas with high ambient light and eliminates the risk of casting shadows on the screen.
