The term Lighting refers to how light has been used by the Cinematographer and Director. At its most basic level, lighting allows film-makers to capture an image in the first place.

In this lesson we got taught how lighting works and particularly three point lighting and we had a go at trying to create a scene using three point lighting as you can see either side of this paragraph to help with this we had a step by step in person guide and also we watched a video explaining what  three point lighting is as shown below.

Three point lighting is a standard method used in media such as theatre, video, film, still photography, computer-generated imagery and 3D computer graphics. By using three separate positions, the photographer can illuminate the shot's subject whatever way he wants, while also controlling the shading and shadows produced by direct lighting. The key light shines directly upon the subject and serves as its  illuminator more than anything else, the strength, colour and angle of the key determines the shot's overall lighting. For indoor shots, the key is commonly a camera's flash. In outdoor daytime shots the Sun often serves as the key light. In this case, of course, the photographer cannot set the light in the exact position they want, so instead arranges the shot to best capture the sunlight, perhaps after waiting for the sun to position itself just right. The fill light also shines on the subject, but from a side angle relative to the key and is often placed at a lower position than the key. It balances the key by illuminating shaded surfaces, and lessening or eliminating effects, such as the shadow cast by a person's nose upon the rest of the face. It is usually softer and less bright than the key light, and more to a flood. Not using a fill at all can result in stark contrasts across the subject's surface, depending upon the key light's harshness. Sometimes, as in low-key lighting, this is a deliberate effect, but shots intended to look more natural and less stylistic require a fill. In some situations a photographer can use a reflector as a fill light instead of an actual lamp. Reflecting and redirecting the key light's rays back upon the subject from a different angle can cause a softer, subtler effect rather than using another lamp.
