Answer:
Choose a dark room that has little or no ambient light, as that can ruin your exposures. You also need to have a blank wall where you can project your images. If you want a small projected image, place the projector at least four feet away from the wall. But if you want a bigger projection, place it at least 8 feet or more. Remember that the farther away you are, the larger the screen.
