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.
A lens is generally considered to be wide angle when its focal length is less than around 35 mm (on a full frame; see camera lenses: focal length & aperture). This translates into an angle of view which is greater than about 55Â° across your photo's widest dimension.
