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.
Wide Angle Lens A wide angle lens is basically a âfar zoomed outâ lens; it can capture more of the scene than the human eye can focus on. A typical wide-angle lens has a focal length of 24-35mm. Ultra-wide-angle lenses, which capture even more of a scene, have very short focal lengths of 24mm or less.
