A common one is for an establishing shot that introduces the audience to a new scene or location. Since there aren’t any cuts, a long take smoothly draws us into the space via continuous look at the setting and moving parts.

A one-shot cinema, one-take scene, continuous shot feature film, or a “oner”, is a full-length movie filmed in one long take by a single camera, or manufactured to give the impression it was. …

A take is one run of the camera, recording a single shot. During the production of a film, it is not unusual for there to be several takes of one shot, with the preferred or best take being decided upon during the editing process. In addition, the number of the take is spoken aloud and recorded onto the soundtrack.

Take. a single continuously-recorded performance, shot or version of a scene with a particular camera setup; often, multiple takes are made of the same shot during filming, before the director approves the shot; in box-office terms, take also refers to the money a film’s release has made.

Lens: A lens is a piece of a refracting medium bounded by two surfaces, at least one of which is a curved surface. The commonly used lenses are the spherical lenses, which have either both surfaces spherical or one spherical and the other a plane one. It converges a parallel beam of light on refraction through it.

There are two main types of lenses, known as convex (or converging) and concave (or diverging)./span>

The two main types of lenses are: Convex Lens (Converging) Concave Lens (Diverging)

Lenses can be classified into subgroups like prime, macro, wide angle, normal, telephoto, and zoom lenses. They’re also rated in regards to f-stop or speed. An example would be a 50mm f/2.0 lens or an 80mm f/1.4 lens.

Plano-concave – A lens in which one side is concave and the other is plano. Plano-concave lenses are diverging lenses. Positive meniscus – A converging lens where one side is concave and the other convex. Negative meniscus – A diverging lens where one side is concave and the other convex.

• A convex lens is employed in microscopes and magnifying glasses to converge all incoming light rays to a particular point.
• The convex lens is used in cameras.
• A convex lens is used for the correction of hyperopia.
• The converging lens is used in the projector as well.

The lens of the eye is a convex lens. It fine-tunes the focus so an image forms on the retina at the back of the eye. Tiny muscles control the shape of the lens to focus images of close or distant objects./span>

A concave lens is a lens that possesses at least one surface that curves inwards. It is a diverging lens, meaning that it spreads out light rays that have been refracted through it. A concave lens is thinner at its centre than at its edges, and is used to correct short-sightedness (myopia)./span>

Case 2 – Object is between Infinity and Optical Center

Convex lenses are used in microscopes, magnifying glasses and eyeglasses. They are also used in the cameras to create real images of objects present at a distance.

Definition of Convex A convex shape is the opposite of a concave shape. Just like concave, convex can be used as a noun for a surface or line that curves outward, and it also has a use in geometry, where it describes a polygon with interior angles less than or equal to 180°.

In general, there are two types of spherical lenses. So, lenses formed by binding two spherical surfaces bulging outward are known as convex lenses while the lenses formed by binding two spherical surfaces such that they are curved inward are known as concave lenses.
