Techniques Glossary White light
A light source that contains a mixture of all wavelengths of the visible spectrum.
white light
visual sensation that results when the wavelegths between 400 and 700 nanometers are combined in nearly equal proportions; light that emits all wavelengths of the visible spectrum at uniform intensity.
White Light
The 1,000 or so colors humans who are not Color-blind can discern have their origin in white light. The Hues we attribute to any object depend upon how the surface reflects and absorbs light and how the eye interprets it.
White light
Light containing equal amounts of the primary additive colours of light. The human eye sees this light as colorless.
White point
The results of combining the additive primary colours, Red, Green, Blue.

White light is a combination of many wavelengths. It can show up tonality in all colours. However, the wavelengths may not be evenly distributed: the light may have a colour cast.
White light consists of all of the colors mixed together. The color of an object depends on how it absorbs and/or reflects light. If an object absorbs all of the light wavelengths, it will appear black.
White light lamp, range 0.5 - 3 m (1.6 - 9.8 ft).

White Lightnings are nice equipment - a good value, reliable and powerful (f16.4 @ 10' w. umbrella). In some location situations, they can have advantages over powerpack lights (placing an accent light 30 to 50 feet away from the power packs).
White light produced by a light source with a low colour temperature such as a tungsten light bulb is very orange compared to the bluish white light produced by a light source with a high colour temperature , such as the sun.
White Light see White Light Spectrum.
White light control is the level or switch on a color enlarger which removes all color filtration and returns it when required.
Pure, white light is composed of a balance of these colors. However, light is not always pure. Often, the color balance of the light has been altered.
Not all white lights are the same. Differences in white light are commonly described by their color temperatures (rated in Kelvin). The lower the number, the warmer the light; the higher the number, the cooler the light.
A beam of white light contains every color. Therefore, in terms of light, every color combined equals white. When an object appears to be white, it is because the object is reflecting every single color towards us.
A beam of white light (entering upwards from the right) is dispersed into its constituent colors by its passage through a prism.
Also, in color theory, the degree of purity of a hue in terms of mixture with white light. Schottky Diode A junction or barrier formed by the direct contact of semiconductor materials with a metal.
Cyan, magenta and yellow pigments serve as filters, subtracting varying degrees of red, green and blue from white light to produce a selective gamut of spectral colours.
Wash-white light 5. Dry-white light In addition to exposure, there are four factors in development that control image density, contrast, and, to a limited degree, the uniformity of individual densities in a negative.
The synchronization signal for these are sent from the screen using white light and not from a separate transmitter. European Format A stereo format which uses stereo pairs of 7 perforations (film sprockets) per image.
So, for example, the red our camera sees might be a red subject under white light or a white subject under red light. The only sure way to correct for this type of error today is with careful setting of the white balance for each scene.
The strobe I usually use is a White Lightning Ultra 1600, powered by a Vagabond battery pack. If I have to do a bit more walking, I use two Canon Speedlites stacked together with a thick rubber band.
To get around the aforementioned limitations of white light slaves, camera manufacturers and independent flash equipment makers have come up with a number of ingenious triggering systems.
This photo was taken in my home studio using my 1Ds MK II at ISO 100 and White Lightning studio lights. I did an in camera 'custom white balance' using an ExpoDisc pointed at the lights.
SOLARIZATION - Print solarization occurs when a photographic print is partially developed, then exposed to white light before the print is completely developed. The effect is a reversal of all or some tones - i.e.
White lights can be turned on while the print is in the stop bath. If the colors in the print are yellow, brown, or reddish- brown, any normal fixing bath can be used. However, take care not to over- fix, or a color shift may occur.
Manufacturers include Bowens, Elinchrom, Novatron, Photogenic, White Lightning, and a host of others and all are available as studio lighting kits.
Flash is a very intense white light. We've all seen those images where the flash has completely overexposed or washed out the color in a scene. Flash can destroy the light tone of a scene.
5000 kelvins is what we photographers call white light and is represented by 'average daylight', whatever that is, actually it's fairly obvious if you look at the chart below.
Dispersion A phenomenon in which white light rays deviate by different wavelength amounts resulting in a spectrum. The rainbow created by a prism is the result of dispersion.
Because the process involves absorbed instead of emitted light, CMYK is a subtractive color model (you start with white light and create colors by absorbing certain wavelengths of that light).
The reason for that is, the three filters transmit, sequentially, the primary colors in white light, red, green, and blue. To make an exposure, set the camera on multiple exposure. Take the first exposure using a red filter.
Abbreviation for Kelvin temperature, the measurement of the redness or blueness of white light. This is written without the degree sign.
The pigments subtract colors from the white light reflected off the paper. Yellow ink looks yellow because it absorbs (subtracts) everything except the yellow from the white light that is illuminating the page leaving on the reflected yellow light.
White light is comprised of all of the colors in the spectrum, so more light means more color. Look at photos that you've taken that should be very colorful, yet look drab, muddy and colorless.
Normally white light is used, but even then there would be a difference between illumination by daylight and illumination by tungsten light.
For most purposes white or quasi-white light is used, as it contains all the colors of the spectrum. This approach is objective, in the sense that by filtering, you get a certain color only if the incoming light contained that color.
Color that has a low saturation level appears washed-out or pastel-like, because it has a lot of white light mixed in the color. Completely unsaturated is grey, while very saturated color is intense and contains little or no white light.
The degree to which a color is undiluted by white light. If a color is 100 percent saturated, it contains no white light. If a color has no saturation, it is a shade of gray.
Scanner ...
I use Alien Bees monolights from White Lightning. They work perfectly for advanced amateur and professional location photography. You can also use them in the studio of course. But they are highly portable, work perfectly and are very well built.
Saturation
The degree to which a color is undiluted by white light. If a color is 100 percent saturated, it contains no white light. If a color has no saturation, it is a shade of gray.
@simon I really like the idea of the white light from the computer screen when you open a new document. I may give that a try!
Also, I am sure I have either a coffee filter or a pringles can lid around here most of the time.
I had Denny Manufacturing paint a special pink canvas with diagonal streaks in white light and blue that matched the elements I intended to use in the photograph.
Two colours are complementary to one another if, when combined in the correct proportions, they form white light. The term is usually applied to the dye colours, which are complementary to the primary additive colours of transmitted light.
Also known as the Sabbatier effect. Usually achieved by exposing a developing image to white light during the development process. The effect is a partial reversal of the image.
Nikonians Photo Glossary ...
Both of these films are designed to be used in the yellow-white light of photofloods that are specifically balanced for 3200 degrees. Household lamps may vary slightly from this color temperature, especially if they are old.
In color reproduction, equal parts of red, blue, and green light give us the sensation of white light. These colors are used in the form of filters in order to create the complementary colors, cyan, yellow and magenta.
A colorful object such as a leaf appears green because when white light strikes it, the leaf reflects only the green wavelengths of light and absorbs the others.
Equipment - You need a few pieces of equipment to pull this off: Table, two bright white lights on stands/lamps, tripod, digital camera, white sheet
2 ...
Also known as color purity or the amount of color density, the degree to which a color is diluted by luminance, or white light.
scale:
To enlarge or reduce an image by increasing or decreasing the number of scanned pixels.
Process whereby color images are produced, usually in scanners, by illuminating the object to be imaged with white light which is made to pass through three successive colored filters. Contrast with three-light method. See color model and scanner.
bend the rays of some colors more than others; a prism placed in the path of a ray of white light bends the blue and violet rays more than the orange and red, so that it spreads out or "disperses" the colors as a continuous spectrum.
A camera system which adjusts the colour balance of the image to compensate for non-white light, e.g. fluorescent light, sunsets etc..
X3 Sensor ...
Then paint directly on that layer with black or white; black darkens and white lightens. Start with a soft, low-opacity brush and build it up. You can do this twice, using one layer for dodging and one for burning.
When you think about the concept of a commercially silhouetted shot, you realize that it's basically about capturing subject matter in some idealized, dirt-free environment: a white room emanating white light from every direction.
The last tip I feel people need to know about shooting with fluorescent lights is that they produce little if any magenta light. As you probably learned in grade school, what we see as white light is actually made up of all the colors of the rainbow.
Is usually used in reference to the visible part of the electro-magnetic spectrum, i.e. the color bands produced by diffraction, and arranged according to wavelength, when white light is passed through a prism.
Speed: ...
Fix
Chemical process which converts unused light-sensitive silver-halide crystals to a soluble silver complex in both negatives and prints, making the image stable and unalterable in white light. Also referred to as hypo.
(see Hypo) ...
Achromatic Color - The primary colors of light (red, green, and blue) used by scanners, monitors, and other computer devices. When combined, they produce white light.
One technique is to shoot your subject in a dark room with a bright light source shining through a window. One side of your subject will be bathed in hot, bright colors or sharp, white light, ...
