Lighting is an important type of equipment used in photography and cinematography to provide the desired illumination needed to obtain an expected result. It is used in a variety of ways depending on the situation and on the desired end product. Lighting can be natural or artificial. Natural lighting is often the best choice, as it can provide the most natural looking results. Artificial light can be used to supplement or even replace the natural light, making it easier to control the light for the desired outcome. Lighting can be manipulated in a variety of different ways to achieve the desired effect. It can be diffused using things like umbrellas, bounced off of reflectors, and colored gels can be used to tint the light to have the desired hues. Lighting can be used to create a mood or atmosphere. For example, dim lighting can be used to create a creepy feeling or a blue hue can be used to create a calming or slightly sad atmosphere. By using multiple lights and lighting setups these effects can be even further amplified. Because lighting is so important to good photography and cinematography, it is important that photographers and filmmakers take the time to study and learn about lighting setups and techniques. It takes practice to know what setup and arrangement of lighting will work best in any given situation or desired effect.
