1.4.2.4 MINIATURES

Models and landscapes that are built to some relative scale make large objects like cities, ships and science fiction vessels possible on film. The sky's the limit. Many films have been made with miniatures standing-in. Scaled miniatures can be built of nearly any appropriate material, as long as it looks convincing. All miniatures must be shot carefully, not to reveal their actual size. To maintain the illusion of scale, there are two simple techniques that are very effective. First, shoot with the lens set to a very small F/stop (F/8 -> F/22) to maintain depth of field and keep every part of the miniature in focus.

Miniatures only look small up close because your eyes cannot see both up close and far away at the same time. Something huge is all in focus because it's usually beyond arm's distance, which the eyes can keep in complete focus. For example, if you look at a book at the end of your nose, the rest of the world behind it goes out of focus. It doesn't look like a 500 foot tall monolith to you because you're busy focusing your eyes up close. If you were to look at a real 500 foot tall monolith, it would all be in focus to your eyes because it really is big. A deep zone of depth-of-field on a miniature can simulate that kind of scale by keeping every part of it in focus. Maintaining the illusion of scale can also be augmented by using a mist of fog (like dry ice or aerosol); we are used to seeing haze in the atmosphere and any landscape miniature would profit from a bit of atmospheric haze. If something really big were to move, you would have to shoot at a higher speed (slow-motion photography) to scale up its speed. For example, if you wanted to create the illusion that your foot long model is supposed to look like a fifteen foot long truck falling off a cliff, you would multiply your frame rate (24FPS) by the scale of your model; in this case, 24 multiplied by fifteen, so you would have to have a camera capable of shooting at a frame rate of 360 frames per second to slow down the fall so its scale looks convincing on screen.
