If you want to truly master understanding white balance, we take a look at the following concepts. Color temperature this concept is an important field of photography, but have a lot of photography enthusiasts don't know its true meaning. In general the reader's eye, colour and temperature are wind horses of different areas in photography, light always according to their color temperature to define. Color temperature is Kelvin. And Fahrenheit, Celsius, Kelvin is the temperature of a unit of measure. Color and Kelvin temperature blackbody radiation originating from the body (it is heated until it glows) at different temperatures rendering of color is the color temperature. When the black body heat when you begin to glow becomes a dark red, if you continue heating becomes yellow and white, and finally becomes blue. This color temperature phenomena in daily life are very common, and believe that everyone is familiar to it. Cloudless blue sky color temperature of about 10000K, cloudy approximately 7000-9000K, sunny sunlight under 6000K color temperature is about, fluorescent color temperature of about 4500 K, tungsten color temperature of about 2600K, sunrise or sunset of color temperature of about 2000K, candle light of color temperature of about 1000K.

Color temperature for a digital camera, is the white balance, which is a lot of photography lovers more headaches.

In a variety of lighting situations, objectives of color will change. In this context, the white object change is obvious: in indoor light, tungsten light, white objects will look with orange tints, this illumination shooting scenes are yellowish; but if you are in the blue sky, with a blue tint. In such an illumination shooting scenes will too blue.

Now that digital cameras have the white balance sensor, generally located at the bottom of the camera.

White balance body will attempt to put white made into pure white. If this is the brightest portion, it will strengthen the yellow and blue, to reduce the screen of the yellow color to find more natural colors. The camera as long as the film white objects correctly restore objects white, can the same lighting conditions correctly restore objects of other colors.

Now digital camera white balance adjustments usually have 4-5 model, because the manufacturers of slightly, but the difference was not significant.

In Canon's digital camera, generally consists of automatic, manual, outdoor, indoor, etc. In the outdoor mode, the camera's white balance function will enhance the image of yellow, and when you're in the sunny outdoor shooting, you can set the white balance function in outdoor mode; if you mistakenly set indoors pattern, white objects will appear in blue color. In indoor mode, the camera's white balance function will enhance the image of the blue, in the light of indoor tungsten bulb, you can set when shooting indoors. If you mistakenly set the white balance in outdoor mode, screen color will become too yellow.

Indoor and outdoor mode that is specific to the sunny sunshine time outdoor and used about tungsten bulb 60W of indoor lighting, both representative light tones of white balance adjustment, and do not represent the full range of indoor and outdoor environment of white balance adjustment, do not possess common sense.

Therefore in some special color temperature setting, or adjust the white balance manually.

Beyond the automatic white balance adjustment range of lighting conditions, will be filming the light source under the manual white balance adjustment.

Manually adjustable front need to find a white reference, such as pure white paper — the kind of thing, with lens alignment it is filled with the camera viewfinder, adjust the manual white balance (different machine adjustment method, you can refer to instruction, usually hold the manual white balance button 1-2 seconds after the prompt), some cameras equipped with white lens cap, so long as the lid white lens cap can be white balance adjustment. Note that must be taken to spot light.

The procedure is as follows:

The camera zoom lens to the maximum wide angle (short focal position); white lens cap (or white) cover the lens with the strict; white balance to manual position; the lens alignment of the clear sky, be careful not to direct sun, closer to the lens until the entire screen white; press the white balance adjustment buttons until you find like reader manual white balance symbol stops flashing, then adjust the white balance manually.

Manually adjust the white balance you can get some special effects, such as: shooting red sunset, on the blue reference manually adjust white balance, you can take out full of warm atmosphere of the picture.

But if the camera's white balance setting on the auto position, the camera will sunset warm color temperature misjudgment into indoor, thus compensating the blue screen and reduce red, sunset atmosphere full of warmth. In contrast to the Red reference manually adjust white balance, you can take out the cold tones of blue.
