George Eastman American entrepreneur and founder of Eastman Kodak Company
"Light makes photography. Embrace light. Admire it. Love it. But above all, know light. Know it for all you're worth, and you will know the key to photography."
One of the most important elements of photography is LIGHT!Light allows us to capture images that convey a mood and emotions. Understanding light and how to control it, is understanding photography!
Light is defined as the visible radiant energy responsible for the sense of sight and may refer to sources of illumination such as sunlight or a lamp. Without light, photography would not be possible, as light illuminates the scene and allows the camera to capture images.
Intro to Light in Photogaphy
Light is a key factor in creating a successful photograph. It determines the brightness and darkness of an image and sets the tone, mood, and ambiance of the subject.
Light has an extraordinary power to convey the emotions in your images to resonate with the viewer.The key to mastering photography is to focus on lighting techniques.
Artificial LightSources
Natural LightSources
All light is emitted by a source, most commonly a heat source or a thermal source. There are many types of light sources, but they can all be categorized into one of TWO categories:
Types of
Light Sources
Natural light is ambient light emitted by natural sources instead of a camera flash or another artificial light. Nature offers many natural light sources, including the sun, moon, and stars. Sun is a primary source of light. It emits visible light, infrared light, and ultraviolet light. Natural light changes from a yellow to a blue tone throughout the day and cannot be controlled or manipulated.
Natural Light
Sources
Is considered artificial because it's human-made.
FIRE
Light can also be produced artificially, as you can see by looking around you. Artificial light is widely used in homes, commercial buildings, and a variety of other settings. They are available in different shapes, sizes, colors, and brightness levels. Artificial light can be fully controlled by manipulating its color tone, intensity, quality, and direction. Sources include flashes, strobe lights, fire, and permanent lights.
Artificial Light
Sources
- Incandescent light sources
- Luminescent light sources
- Gas discharge light sources
Types of
Artificial light sources are categorized into one of three broad categories:
Artificial Light
Sources
Incandescent light sources emit light when heated to a high temperature. Visible and infrared light are produced during the process. These incandescent lights range from the common light bulb to large tungsten hot lights used in photography studios and movie sets. Incandescent lights emit a warmer, more yellow color tone compared to natural daylight.
Examples of incandescent light sources include fire, candles, and incandescent lamps.

Luminescent Light
Luminescent light sources, such as fluorescent tube lights, are used in most buildings and offices. They produce a cool white or bluish light tone. Luminescent lights are NOT commonly used in photography, but shooting in settings where they are used can create challenges. To correct the harsh blue light, photographers adjust settings in their cameras.
Examples of luminescent light sources include fluorescent lighting tubes and electric light bulbs.
Luminescent Light
When electricity passes through certain gasses at very low pressure, it produces a neon light. These are called gas discharge light sources.Examples of gas discharge sources include neon lamps and sodium lamps.

Types of Light Quality
Light has distinct qualities that create different visual moods in a photograph. Lighting quality refers to how the light source, either natural or artificial, is adjusted for a subject.The position and quality of light affect the clarity and sharpness, tone, contrast, emotion, and texture of your photograph, as well as other factors.
The TWO factors that determine the quality of light are the SIZE of the light source in proportion to the subject & the DISTANCE between the light source & the subject.
There are FOUR main types of light quality:
- HARD light
- SOFT light
- SPECULAR light
- DIFFUSED light
Types of Light
Quality
The transition between the light and the shadow is harsh and defined due to the bright lighting that the sun provides.This results in a high-contrast look.
HARD LIGHT
Hard light is created when the light source is SMALLER and FARTHER from the subject.Hard light is a bright light that casts distinct harsh shadows and draws attention to a specific part of a photograph.Hard light adds dimension and depth to your images. It results in a high contrast that creates a strong sense of drama and gives your photos an edgy and gritty look.An example of a natural source of hard light is direct sunlight. Although the sun is small and extremely far away, the light can be very intense. An artificial source of hard light is a camera flash.
HARD LIGHT
The larger and nearer the light source is to the subject, the softer the light will be. Soft light is flattering, it casts SOFT shadows that are bright yet balanced and not sharply defined. Smaller and finer details do not appear in shadows, so soft light results in low-contrast images. An example of an artificial soft light source is a lamp covered with a lampshade used in a home. A natural source of soft light would be the sunlight that comes in through a window.
The transition between the light and the shadows is more gradient and much smoother, resulting in a low-contrast image.
SOFT LIGHT
Soft Lighting
Soft lighting is commonly used for portrait photography, as it smooths skin, hides acne, and brings out the light in a subject's eyes. It is widely used in fashion photography, travel photography, and food photography as well.
The light sources emit DISFUSED light that is LARGER and CLOSER. This spreads out the light and softens it.

Soft Light vs Hard Light & Diffusion
SOFT Lighting
HARD Lighting
- Bright light & strong shadows
- High contrasts between light and shadow
- Creates a sense of drama and depth
- More flattering
- Soft, light shadows
- Low contrasts
- Transitions between light & shadows is more gradual
When the light passes through a semi-transparent or translucent material on the way from the source to the subject, it gets diffused. Diffused lighting sources are uniform all over their surface. Diffused light and soft light are different from one another. Soft lighting refers to the soft shadows, while diffused light distributes the light equally along its surface. For example, when the clouds are present in front of the sun on an overcast day, the light gets diffused. A sheer curtain over a window is another example of a light diffuser.

Soft Light
Specular light is defined by the existence of strong highlights and shadows in the photograph. Details in the center of the photograph may be incredibly bright, while details toward the edges may taper off into the darkness. For example, the light generated by a traditional flashlight or spotlight illuminates bright areas in the center of an object. Observe the image on the right. The light at the center is stronger, but it becomes smudged at the edges, and the subject stands out from the background
Specular Lighting
HighIntensity
LowIntensity
The intensity of light refers to the brightness level of light used. This is what makes your subject stand out. The intensity of light is affected by the size of the light source, the intensity of the light sources, as well as the distance between the light source and your subject. If you increase the distance between your subject and light, the intensity of light will decrease. Whereas, if you bring the light source closer, the intensity of light will increase.
intensity of light
Each natural or artificial light source has its own individual color, or 'color temperature, on a scale from red to blue.
- The HIGHER the Kelvin value ,or color temperature, the bluer or cooler the light color. Cool colors tend to recede visually and look 'smaller' in a composition.
- The LOWER the Kelvin value, or color temperature, the warmer the light color.
Light color temperature determines the characterization of the spectral properties of a light source. Color temperature is measured in standard Kelvin (K) units and is a physical property of light.
light color Tempature
The Kelvin Scale
As the name suggests, white or neutral color balancing is referred to as white balance in an image. The human eye is excellent at adjusting to different color temperatures. This means objects appear roughly the same color regardless of outdoor sunlight or indoor artificial light. Digital cameras, however, view objects as different colors depending on their lighting. This causes photographs to form a color cast– an overall blue or orange tint that makes the photograph appear unnatural and unpleasing.
White Balance
White Balance Made Easy
White Balance throughout the Day
WHITE BALANCE PRESET
DSLR cameras correct these color casts by optimizing the color temperature of the scene with the help of preset white balance settings. Auto WB preset (white balance) is a default setting in the camera that automatically corrects the color cast depending on ambient light and the use of flash to compensate for different color temperatures.
Custom WB or K preset in advanced DSLRs allow users to set the white balance color temperature manually in this mode by adjusting the Kelvin value.

FlourescentPreset
The cloudy preset setting generally warms the colors more than daylight mode. It is good for capturing portraits.
Shade has a cooler tone than direct sunlight.The shade preset will warm things up and give you more neutral looking skin tones in portraits.
The flash of a camera has a cooler tone than direct sunlight and using flash WB mode can warm up your photo and prevent skin tones from turning cold in portraits.
Fluorescent preset is indicated by a glowing tube and warms up your photos by compensating for the cool blue light of fluorescent light bulbs or tubes.
TungstenPreset
Tungsten preset cools down the color in photos by adding the opposite color.
White Balance Preset
Daylight/Direct Sunlight preset is indicated by a sun symbol. It's calibrated to set fairly ‘normal' (neutral colors) white balance settings under midday sun. It can be used as a fixed standard for capturing colors exactly as they are in non-standard lighting conditions.
- You can set your camera to default– select the auto WB setting and let the camera's electronic brain evaluate the scene to figure out the best white balance settings to use.
- You can look at the color cast and set a preset white balance depending on the lighting conditions (sunny, cloudy, shady, fluorescent, tungsten, or flash).
- You can control the white balance of your images manually by setting the Kelvin temperature scale to a neutral one based on the scene.
You have learned three basic approaches that you can take to white-balance your images:
