Low light focusing
If you have difficulty focusing in low light, follow these suggestions.
Flash illumination is produced by an electrical discharge though a glass tube filled with gas (often Xenon) at low pressure. This is a short burst of light, typically lasting 1/1000s or so.
Angle Of Illumination - See "Flash Coverage."
Angle Of View - The area of a scene that is captured by a lens, such as normal, telephoto or wide-angle.
Source of illumination that lightens shadows.

The angle of illumination is important and varies with different types of subject.
Peripheral Illumination Correction is a nifty new feature that detects which Canon lens is mounted on the camera and compensates for any light fall-off, so image brightness will be consistent throughout the shot.
Fill-in. Illumination to lighten shadows, reducing contrast.
Fill lighting. In photography, lighting used to illuminate shadows.
Film speed. Measure of sensitivity of film to light. Usually expressed as an ISO figure.
Computational illumination
Controlling photographic illumination in a structured fashion, then processing the captured images, to create new images.
Control Panel Illumination
On cameras with a control panel, it can be hard to check your settings in dim light. Check to see that the camera has a button you press to illuminate this panel.
Backlight - The illumination for a color LCD display. Early color LCD used high voltage fluorescent lamps, newer LCDs now use white LEDs which are much more energy efficient.
FLAT LIGHTING - Illumination that provides little contrast on the subject and light or imperceptible shadows.
Unit of illumination (cd). 1 cd is 1/683W per steradian.
[CANDLE]
A preset setting on the camera. It is one of the selections for the [SCENE] function. Use this setting when taking pictures under the lighting of a candle or an incandescent lamp.
A color filter that transmits only those wavelengths of the illumination light that efficiently excites a specific dye. See Emission filter.
The former ensure vision at lower levels of illumination, while the latter account for higher light levels and the color that we see.
As a matter of fact, I use flash more often outdoors in daylight than I use it indoors as a main source of illumination. In the two accompanying photos, here’s the thinking behind my TECHNIQUE.
Reflectors are often used in photography to soften the effect of the main light or to bounce illumination into subjects shadows. Light does not always fall exactly where you want it. For this reason reflectors are used.

Built-in model lights: Certain strobes, like the Ikelite 200/DS125 and Inon Z-220, have very powerful built-in modeling lights that provide sufficient illumination for night diving.
No matter the time of day or the location, you can dramatically change the tone of the photograph simply by shifting the illumination of your subject.
Put the slide on a light box, or some other source of even illumination and look at the it though the lens, with the back of the lens to your eye and the front facing the slide.
Digital
If you're shooting digital you can do much the same thing.
Diffused window light gives us this type of illumination where contrast is held to a minimum. Photo (#1) was taken next to a large French door, and you can see how low in contrast the lighting is.
Developed by the Commission Internationale de l'Eclairage (International Commission on Illumination), it still uses three color channels, but not for red, green and blue.
Generally, when a ringflash is used as a single light, the results show an even illumination on the object or model with slightly darker contours and shadow contours all around.
You can also bounce or diffuse the flash to control its angle of illumination. Bouncing the flash off a white ceiling or a bounce reflector gives a soft effect. You can also soften the light by adding a diffuser in front of the flash.
A fairly recent development in continuous photographic lighting is fluorescents, which are cooler and provide nice soft illumination. Because they are cool, you can place them quite close to your portrait subject.
The angle of coverage for even, uniform, edge-to-edge illumination by a speedlight. Usually expressed in terms of focal length.
The camera's light sensor measures flash illumination, as reflected by the subject on the film and shuts off the flash where measurement indicates a correct exposure.
Similarly, film is manufactured to give you accurate colors indoors with tungsten illumination balanced for 3200 degrees Kelvin. Examples include Fujichrome 64T and Ektachrome 50.
This will test your strobist skills: Try balancing the illumination across a scene where both interior and exterior spaces need even, natural-seeming, and color-correct light.
The fun with B really starts if you photograph subjects where you have to provide the illumination yourself either with flash, a powerful torch, or a combination of the two.
A (Non-TTL Auto mode on Nikon Speedlights) The flash uses its sensor to measure the flash illumination reflected back from the subject controlling flash output to give correct exposure.
An enlarger using cold cathode illumination. A diffusion type of enlarger. These types of enlarger heads scatter the light more evenly across the surface of the negative.
Vignetting means that there's a decreasing (=darker) illumination towards the image corners.
If you like low tech, and if you like taking photos in dim illumination, film could still be the better choice for you.
The sun will act as the main illumination for the image, and the flash is going to act as our rim light. Rim lights illuminate the edges of the subject and are usually brighter than the main light (in this case, the sun).
The main area of confusion in EOS flash photography is the fact that P, Tv, Av and M modes handle flash illumination differently, especially when ambient light levels are not bright.
Since light can wreak havoc on photographs, choose a storage space that protects and shields prints from illumination. Fireplaces, furnace vents, light bulbs, candles and sunlight generate light and heat that can destroy family photos.
International Commission on Illumination (Commission Internationale de l'E'clairage). The CIE established an international standard for primary colors in 1931. This standard allows all colors to be defined as a weighted sum of three primary colors.
The rectangular area of illumination formed on a TV screen by the scanning process. An array of lines or dots of varying brightness which, when viewed from a suitable distance, produces the illusion of an image.

This gives you the most illumination, continuously, so you can focus. Move the whole head up or down until the image is about the right size, using the crank or handle. Then find the focus knob, and move it up or down and focus the image.
When such a print is solarized with a diffuse light source (that is, when all parts of the highlight areas receive the same level of illumination in the Sabatier exposure), the highlight areas naturally end up with a featureless, uniform density.
When using flash in dim light (when the flash will be the main source of illumination) it is very hard for me to avoid washed out, ...
-Fill light - source of illumination that lightens shadows. See Fill-in.
-Film - photographic material consisting of a thin transparent plastic base coated with a light sensitive emulsion.
Vignetting
Fall-off in illumination at the edges of an image. This can be caused by poor lens design, using a hood not matched to the lens, or using too many filters at the same time.
W ...
General name given to illumination that's produced from an electrically heated source, such as a lamp's tungsten wire filament.

Basically all the inverse square law says is that an object that is twice the distance from a point source of light will receive a quarter of the illumination.
