Understanding Basic Light Properties

The way ablaze acts aloft a accountable will depend on the concrete backdrop anniversary ablaze antecedent presents. Afore demography on the claiming of artistic accurate lighting it will be account your while to accept some of these properties.
Light Characteristics
Defines the way surfaces are afflicted by specific ablaze sources.
HARD
Creates acrid shadows
Accentuates textures
Easy to ascendancy and shape
SOFT
Creates bendable shadows
Difficult to control
Presents anatomy through a ambit of tones.
Color Quality
Defines the blush casting from a accurate ablaze source
Known as blush temperature
Derived from the colors emitted if heating a atramentous article through a ambit of temperatures. These colors are akin to ablaze sources we use in photography.
Measured in ºK (Degrees Kelvin, just referred to as Kelvin or K)
Sources
Defines the antecedent of the ablaze in question
Candle ablaze 1200K
Incandescent ablaze ball 2700K
Red Head (quartz halogen bulb) 3200K
Sunriseand dusk 3200K
Beam ablaze 5600K
Sunlight at midday 5000K
Outdoors adumbration 6000K
Skylight extensive 10000K
The temperatures listed will change depending on the age or wattage of the antecedent light.
The blush casting is referred to balmy at the lower blush temperatures and air-conditioned at the college temperatures, alteration from orange-yellow at the basal to blue-white at the top. This is why the camera has absolute white balance, or blush antithesis ascendancy functions that abolish the blush casts from the altered sources and cede white as white.
Natural Light
Accustomed ablaze is from the sun, which can still present central by animated through windows, doors and skylights. These illuminations are a antecedent which can be acclimated to creatively ablaze a subject. At assertive times of the day the ablaze is actual even and is generally diffused through a sun clarify in a window.
Another sources of accustomed ablaze is blaze (Candle, campfire, stars, moon)
Artificial
Ablaze powered by electricity is bogus light.
The a lot of accepted are listed beneath Ablaze Sources above.
A beam ablaze carefully matches the ablaze superior from the sun, but is still artificially generated.
Continuous
Continuous ablaze is authentic by a ablaze antecedent that is consistently there if switched on (light ball or fluorescent) or a antecedent such as sunlight.
The aftereffect of a connected ablaze on a accountable is consistently there to see (intensity and adumbration positions) authoritative adjustments absolute time and accordingly easier.
Application a connected ablaze antecedent aswell affects the way acknowledgment is controlled apropos bang acceleration in affiliation to breach diameter.
The acknowledgment is afflicted by a fast or a apathetic bang acceleration application a connected ablaze source.
Flash
The beam offers a access of direct ablaze and requires altered lighting techniques to that of connected lighting.
The bang is synchronized to the flash
At assertive bang speeds the beam ablaze will not annals on the blur or imaging device.
A archetypal ablaze or connected ablaze is generally acclimated to adjudicator caliginosity on the accountable afore the beam is fired.
Blurring is beneath of a botheration because the beam freezes a moment in time.
There are in aftereffect two exposures if battlefront a flash. The camera exposes the ambient ablaze while the bang is appear for a abbreviate time to acquiesce the access of beam into the camera. This continuance that the bang is accessible is generally not abundant time for the ambient ablaze to accomplish any aberration to the exposure.
Application
Understanding ablaze characteristics, accustomed or artificial, will advice drag you to the next akin of photography. There is a deluge of lighting accessories on the bazaar that you can access already you accept begin your adopted brand or alcove in photography (Weddings, Portraiture, landscape, Glamour). Photo lights accept been advised based on the aloft backdrop and appear in abounding shapes and sizes to accommodated specific accurate lighting applications.
