Oobleck is an example of a fluid whose viscosity is not constant; itâs viscosity changes depending on the stress or forces applied to it. If you poke it with your finger and apply a large force, it becomes very viscous and stays in place. If you gently pour it, applying little force, it will flow like water.
The camera angle marks the specific location at which the movie camera or video camera is placed to take a shot. A scene may be shot from several camera angles simultaneously. This will give a different experience and sometimes emotion.
Angle of View (Angular Field) - The area size captured by a photographic lens is expressed as a diagonal angular field called Angle of View. The shorter the focal length of a lens, the wider the angle of view (wideangle), while the longer it becomes, the narrower the angle of view (telephoto). (ref. Field of View) Aperture - Lens opening. The opening in a camera lens through which light passes to expose the film. The size of aperture is either fixed, as in a reflex or catadioptric lens, or adjustable. The aperture size controls depth of field.
