Understanding Light in Photography

Light is an essential element in photography. It helps to create the atmosphere of the image, bring out the details, and can even transform an ordinary scene into something extraordinary. Understanding light is one of the most important aspects of photography, and it is essential for any aerial photographer to understand how to use it in their work. In this article, we will explore the basics of light in photography, including the different types of light, how to use it for different purposes, and how to use it to create stunning images. Whether you are a beginner or a professional, this article will help you gain a better understanding of light in photography and how to use it to create beautiful photographs.

Ambient Light

: Ambient light is the existing light that is already present in an environment.

It can be anything from sunlight to artificial lighting, such as light fixtures or candles. Ambient light provides a general level of illumination and can be modified by using reflectors, diffusers, or gels.

Natural Light

: Natural light is sunlight or moonlight. This type of light has a warm, inviting quality and is the preferred light source for many photographers.

Natural light also provides the most even illumination and can be used to create beautiful photographs with minimal equipment.

Artificial Light

: Artificial light is any type of lighting that has been created by humans. This includes light fixtures, lamps, and camera flashes. Artificial light can be used to create dramatic effects in photography and can be modified in various ways to control the intensity, direction, and color temperature of the light.

Properties of Light: There are several properties of light that affect photography, including color temperature, intensity, direction, and quality. Color temperature refers to the hue of the light and how warm or cool it is. Intensity indicates how bright or dim the light is. Direction describes the angle of the light in relation to its subject, while quality determines how soft or harsh the light is.

Lighting Techniques: Different lighting techniques can be used to create different effects in photography. These techniques include backlighting, sidelighting, high-key lighting, low-key lighting, rim lighting, and fill lighting. Backlighting involves placing the light source behind the subject to create a silhouette effect. Sidelighting involves placing the light source to one side of the subject to create dramatic shadows.

High-key lighting is a technique that involves using a lot of light to create a bright, airy look. Low-key lighting is a technique that uses less light to create a darker, more dramatic atmosphere. Rim lighting involves using a backlight to create a glow around the subject’s edges. Fill lighting involves using a softer light source to fill in shadows and reduce contrast.

Modifying and Controlling Light: There are several ways to modify and control existing light, such as using reflectors, diffusers, and gels. Reflectors are used to bounce existing light back onto the subject for a brighter effect. Diffusers are used to soften the intensity of direct sunlight or artificial lights for a more even illumination. Gels can be used to change the color temperature of existing lights for creative effects.

Camera Flashes and Lighting Equipment: There are various types of camera flashes and lighting equipment that can be used to create different effects in photography. Speedlights are small flashes that attach directly to the camera and offer great portability and versatility. Studio flashes offer more power and control but require more setup time and space. LED lights are small, versatile lights that offer great energy efficiency and can be used for both stills and video.

Monolights are powerful strobes that provide more control over power output and recycle times than speedlights or studio flashes.

Types of Light

Light is a crucial element of photography, providing the main source of illumination for most pictures. To effectively use light in photography, it is important to understand the different types of light available. We will start by explaining the three main types of light: ambient, natural, and artificial.

Ambient Light

is the existing light in a scene, whether natural or artificial. This includes any light sources that are not directly added by the photographer.

It can be natural light from the sun, moon, stars, or even streetlights. It can also be artificial light from lamps or other indoor lighting.

Natural Light

is light that comes from sources like the sun and moon. Photographers often take advantage of natural light to create beautiful and interesting photos. Natural light offers a softer and more natural-looking illumination than artificial light sources.

Artificial Light

is any light that is added by the photographer.

This includes studio lights, flash units, and other lighting equipment. Artificial light gives the photographer more control over the intensity and direction of the light.

Modifying and Controlling Light

In photography, light is often modified and controlled in order to create a desired effect. This can be done in a number of ways, from using reflectors and diffusers to manipulating the angle of the light or adding artificial sources of light. Reflectors are a great way to modify existing light, as they allow you to bounce light off of a surface and onto your subject.

This can be used to add more light to a photo, or to soften and diffuse the light. Diffusers are another way to modify the existing light, as they allow you to spread out the light source, resulting in softer, more even illumination. The angle at which you shoot can also have a major impact on the quality of light in your photos. By shooting from different angles, you can take advantage of different types of lighting and create interesting shadows. Additionally, you can adjust the direction of the light by using reflectors or diffusers. Finally, if you don’t have enough natural light, you can add artificial sources.

This could include studio lights or flash units that are set up to give you the desired lighting. Additionally, you can use colored gels to modify existing light and create interesting effects.

Lighting Techniques

Lighting is an incredibly important part of photography, and understanding the different techniques used to manipulate light can create stunning images. There are many different lighting techniques available for photographers to use, from bouncing light off a wall or ceiling to using a reflector. One of the most popular techniques is using multiple lights in an arrangement known as a three-point lighting system.

The three-point lighting system uses three separate lights to create a variety of effects. The first light is the key light, which is the main source of light and usually placed in front of the subject to create the main illumination. The second light is called the fill light and is placed on the opposite side of the key light, usually at a lower intensity, to help fill in any shadows created by the key light. The third light is a backlight, which is placed behind the subject and helps to separate them from the background.

Other techniques include using a single light source with flags or diffusers to control the direction and intensity of the light, or shooting with natural light. Natural light can be used to create some stunning portraits, but it requires an understanding of how the quality and direction of the light changes throughout the day. Experimenting with different lighting techniques is key to creating unique images that stand out from the crowd. With practice and experimentation, any photographer can learn how to manipulate light and create beautiful photographs.

Properties of Light

Light has several properties that affect photography.

Photographers must understand these properties in order to make the most of the light they use for their photos.

Color Temperature

The color temperature of a light source affects the look and feel of a photo. It is measured in Kelvin (K) and ranges from 1,000K (red-orange) to 10,000K (blue-white). In photography, color temperature is a measure of how warm or cool a light appears in an image.

Warmer tones provide more orange and red hues while cooler tones provide more blue hues.


Intensity is the amount of light emitted by a source. It affects the brightness and contrast of an image. Intensity can be adjusted by changing the distance between the light source and the subject, as well as the angle of the light.

DirectionThe direction of a light source can have a huge impact on the look and feel of a photo. The direction of light will determine where shadows are formed and how they are defined. It is important to understand how directional lighting can be used to create dramatic effects.


The quality of light refers to its softness or hardness. Soft lighting produces diffused highlights with soft shadows, while hard lighting produces harsh highlights with sharp shadows.

Quality of light can be adjusted by using diffusers and reflectors to control the intensity and direction of the light. Photography is a creative art form that relies heavily on understanding how light works. With a solid understanding of the types of light, its properties, and lighting techniques, photographers can use different techniques and equipment to modify and control light for beautiful imagery. By understanding the basics of light, photographers can create stunning photographs that capture the essence of a moment. With a bit of practice, anyone can become a master of light and create beautiful works of art.
