What are the 2 qualities of light?
INTENSITY and BRIGHTNESS
INTENSITY typical refers to the 'strength' of a light source. Intensity of a source exists independent of its distance. Intensity is measured in candela (The old term was candlepower). ILLUMINATION refers to amount of light falling on a surface.
Here are the five most important qualities of light to consider about light: quantity, direction, color, contrast, and Hard/Soft.
- An introduction to lighting for photojournalists. Note: Many of these photos were taken by photojournalism students in COMM 242.
- The three characteristics of light:
- Intensity. Light can vary in intensity by as much as 1,000 times. ...
- Quality. Light is perceived as hard or soft. ...
- Direction. ...
- Color balance.
Angle, Size, Distance, Shape, Duration, and Color are each qualities of light that photographers can combine and manipulate these qualities in setting the look of their photograph for impact beyond just illumination.
Natural light sources include the Sun and stars. Artificial light sources include lamp posts and televisions.
Light is essential to our health and wellbeing; it regulates our sleep-wake cycle. It can also help with our daily routines: from bright functional light to keep you energized and up your concentration level, to warm light that creates a cozy ambiance that helps you to unwind in the evening.
It is measured in footcandles or lux – it is the amount of light (lumens) falling on a surface (over any given square foot or square meter). Therefore, light intensity is measured in terms of lumens per square foot (footcandles) or lumens per square meter (lux).
Photography is “writing with light.” So, let's build our conversation about lighting on five fundamental characteristics of light: Direction, Intensity, Color, Contrast, and Hardness.
Hard and soft light are different types of lighting that are commonly used in photography and filmmaking. Soft light is light that tends to "wrap" around objects, projecting diffused shadows with soft edges, whereas hard light is more focused and produces harsher shadows.
Light quantity is the number of light particles (called photons) capable of performing photosyn- thesis. Light quantity is more complex because it can be measured in two ways: the instantaneous amount of light (light intensity) and the cumulative amount of light delivered each day (daily light integral).
What is direction in qualities of light?
The simplest of light's qualities is its direction relative to your camera. There are essentially three directions: frontal, side and backlighting. The three directions have a different effect on how three-dimensional your subject appears to be due to the that shadows are cast.

- 2- Fluorescent Lamps:
- 3- Compact Fluorescent Lamps (CFL):
- 4- Halogen Lamps:
- 5- Light Emitting Diode (LED):

- Ambient lighting.
- Task lighting.
- Accent lighting.
- Decorative lighting.
There are three basic types of lighting that work together to light your home: General, Task and Accent.
Light is a form of energy that moves in straight lines. It also reflects off things, and that reflected light enters our eyes, allowing us to see.
Exposure to natural light helps our bodies produce Vitamin D, improves our circadian rhythms and sleep patterns, helps us to focus, enables us to get more done, and even makes us happier.
lux, unit of illumination (see luminous intensity) in the International System of Units (SI). One lux (Latin for “light”) is the amount of illumination provided when one lumen is evenly distributed over an area of one square metre.
Glare can be generally divided into two types, discomfort glare and disability glare.
It is measured in degrees of Kelvin (K) on a scale from 1,000 to 10,000. Typically, Kelvin temperatures for commercial and residential lighting applications fall somewhere on a scale from 2000K to 6500K. A light bulb's color temperature lets us know what the look and feel of the light produced will be.
The light we can see, made up of the individual colors of the rainbow, represents only a very small portion of the electromagnetic spectrum. Other types of light include radio waves, microwaves, infrared radiation, ultraviolet rays, X-rays and gamma rays — all of which are imperceptible to human eyes.
What is light and its types?
Visible light– Can only be seen through the naked eye. It's a form of electromagnetic energy. The source of visible light is the sun. It can also emit from lanterns, flashlights, light bulbs, etc. Infrared light– is also a form of electromagnetic energy that produces heat.
Light is made of particles called photons, bundles of the electromagnetic field that carry a specific amount of energy. With sufficiently sensitive experiments, you can count photons or even perform measurements on a single one.
Soft lighting is a type of light with few hard shadows that's bright yet balanced. In soft lighting, the transition between the light and the shadows is more of a gradient and much smoother. When your subject is bathed in soft light, there will be little to no shadows on their face.
Solid light, often referred to in media as "hard light" or "hard-light", is a hypothetical material, made of light in a solidified state. It has been theorized that this could exist, and experiments claim to have created solid photonic matter or molecules by inducing strong interaction between photons.
Hard light is a quality of light that casts harsh and well defined shadows. A subject or scene lit with this type of light has a very abrupt transition between the highlights and the shadows. Hard light typically comes from a relatively small source relative to the subject.
Brightness is an attribute of visual perception in which a source appears to be radiating or reflecting light. There is often confusion around terms such as luminosity, magnitude, light intensity and how humans actually perceive light.
Quality is a measure of excellence or of a state of being. It describes something, either of how it was made, or how it is as compared to others. Quantity, on the other hand, is the extent, size, or sum of something. It is countable or measurable and can be expressed as a numerical value.
Color quality is a function of the spectral output of a light source, the spectral absorbance/reflectance of an object, and the sensitivity of the eye's cone photoreceptors to different wavelengths of light, which we perceive as color.
Answer: We can change the direction of the light by phenomenon called reflection.
Light often describes the light source or light reflected within the composition. In realistic compositions, if there is light, there is shadow.
What is a light Class 6?
Light helps us see objects. The torch bulb is an object that gives out light of its own. The Sun, is another familiar object that gives its own light. During the day, its light allows us to see objects. Objects like the sun that give out or emit light of their own are called luminous objects.
Light is a type of energy that makes it possible for us to see everything around us. Light comes from different sources called light sources. Light can come from a natural source or a manmade source.
If you look inside a computer or TV screen, you'll see they contain only three colors of light: red, green and blue. The three specific cone cells in our eyes work together, allowing us to translate these three colors of light into millions of different colors.
What is light? Light is a radiation or a form of energy that our eyes can detect. Light enables us to view our surroundings. Light travels from one place to another in a straight line.
Light is defined as the electromagnetic radiation with wavelengths between 380 and 750 nm which is visible to the human eye.
- It is used in solar panels to derive the energy of the sun to perform domestic functions.
- It aids in the production of food and the growth of plants.
- It is utilized in satellites and space stations to provide electricity.
- It is found in a lot of technological gadgets.
Each astrological element is made up of three zodiac signs: Aries, Leo, and Sagittarius are fire signs; Taurus, Virgo, and Capricorn are Earth signs; Gemini, Libra, and Aquarius are air signs; and Cancer, Scorpio, and Pisces are water signs.
- Light is an electromagnetic wave.

What are the characteristics of light in the Bible?
In the Bible, light has always been a symbol of holiness, goodness, knowledge, wisdom, grace, hope, and God's revelation. By contrast, darkness has been associated with evil, sin, and despair.
White light is composed of seven components. These colours are violet, indigo, blue, green, yellow, orange and red.
Light: Light is a form of energy which helps us in seeing objects. When light falls on an object, some of the light gets reflected. The reflected light comes to our eyes and we are able to see an object. Luminous Object: An object which produces light is called a luminous object, e.g. sun, bulb, etc.
In theology, divine light (also called divine radiance or divine refulgence) is an aspect of divine presence perceived as light during a theophany or vision, or represented as such in allegory or metaphor.
Jesus Christ is the light of the world because he is the source of the light which “proceedeth forth from the presence of God to fill the immensity of space” (D&C 88:12). His light is “the true light that lighteth every man that cometh into the world” (D&C 93:2; see also D&C 84:46).
Always pointing back to the light source.
When Jesus said, “Let your light shine before others,” that wasn't the whole sentence. He went on to give the reason why it's important to shine: “so that they may see your good works and give glory to your Father who is in heaven” (Matthew 5:16b).
In western countries such as France and US, red is thought to be the colour that represents love and passion because it is the colour of blood. However, just as it represents the fiery passion of life, it can also symbolize danger because of that same association.
Light is electromagnetic radiation which shows both the properties of waves and particles. It is the form of energy and also keeps the Earth warm. It exists in the form of tiny energy packets known as photons. Each wave consists of the wavelength or the frequency.
