What is F11 illuminant?

CIE F11 illuminant represents a narrow tri-band fluorescent of 4000° Kelvin color temperature, CRI 83. This is a category of fluorescent lamps with narrow tri-band phosphor construction with a 4000° Kelvin color temperature that can be made by several lamp manufacturers.

What is the light source?

Light sources are devices whose primary function is to produce visible or near-visible radiant energy for general illumination and specialty applications. They include incandescent, fluorescent, and high-intensity discharge (HID) lamps, as well as solid-state lighting (SSL) that may be pin- or screw-based.

What is a 6500K light?

Actually, 6500K means 6500 degrees Kelvin. It has nothing to do with brightness whatsoever. It’s the temperature color. 6500K is equivalent to the color of light provided by an overcast, cloudy day, which is slightly (very slightly) bluer than mid-day sun. 5500K is equivalent to mid-day sun color.

Should I use D50 or D65?

For one, the white point of most photographic paper is very blue when viewed under a D50 illuminant. On most displays it is harder to achieve high luminance levels at D50. It is for these reasons that, when working with photographic paper, calibrating to D65 may produce a better screen-to-print match.

Is D65 the same as 6500K?

D65 is not the same as 6500K!

ANSI separately developed its standard for 6500K using the xy chromaticity coordinates of (0.313, 0.337), and most manufacturers will strive to hit this color point as their target color point.

What are the classification of light?

Electromagnetic spectrum and visible light

Generally, electromagnetic radiation (EMR) is classified by wavelength into radio waves, microwaves, infrared, the visible spectrum that we perceive as light, ultraviolet, X-rays and gamma rays. The designation “radiation” excludes static electric, magnetic and near fields.

Which source of light is brightest?

A light one billion times brighter than the surface of the Sun has now been created in a lab, making it the brightest light ever produced on Earth. The record-breaking laser beam has revealed new properties of light, and it could be used in medical equipment or to create more powerful computer chips.

Is moon a light source?

The Moon is not a light source, it does not make its own light. The Moon reflects light from the Sun. We can see the Moon because light from the Sun bounces off it back to the Earth.

How is light made in nature?

Natural sources of light include the sun, stars, fire, and electricity in storms. There are even some animals and plants that can create their own light, such as fireflies, jellyfish, and mushrooms. This is called bioluminescence. Artificial light is created by humans.
