Watch Compass (1980) Official Trailer

When you shoot incandescent light in daylight, the image appears blue. To compensate for this, you put an amber filter on the lens, but if you remove the filter from the lens and move it away from the camera, you will see two areas of different color temperatures. A series of photos was taken while rotating the filter around, and the area inside the filter becomes distorted as the shutter speed slows down.
