Three basic characteristics of light
|
Coherence (quality)color temperatureintensity
|
|
Coherence (quality)
|
The hardness or softness of light.
|
|
Hard light casts
|
Sharp, clearly defined shadow.
|
|
Types of lighting instruments used to create hard light
|
Beam-spot projector
ellipsoidal spotlight |
|
Soft light tends to
|
Hide surface irregularities and detail
used to create broad, even, area of light. |
|
Spun-glass diffusers are used
|
Over the front of lights to soften and diffuse their beams. At the same time diffusers also reduce the intensity of light
|
|
Umbrella reflectors
|
Create a soft lighting effect.
|
|
LED soft light consumes
|
Much less power and generates much less heat than incandescent versions.
|
|
Lifespan of LED lamps is rated at
|
100,000 hours and they can be readily switched from daylight to incandescent color temperatures
basic form LED lights are non-directional, hte light output of some versions can be directionalized, which means they are effective at greater distances |
|
A soft light source placed close to the camera minimizes ________. The effect is commonly referred to as _______.
|
Surface detail
flat lighting |
|
Flat lighting leaves the subject matter somewhat ______.
|
Dimensionless
Although it has certain applications, especially in ECUs of objects where shadows would obscure important details. |
|
A soft light source placed close to the camera minimizes surface detail.
|
Flat lighting
|
|
Used over the front of a light to soften and diffuse their beams
|
Diffuser
|
|
Color temperature
|
Refers to light's basic color. We're also speaking of a characteristic of light that goes beyond the obvious
|
|
Two basic color standards
|
3200 K for incandescent lamps used in studios and 5,500K for average daylight.
