What Is White Balance?
This is a term that refers to the light’s color temperature. Lights have 3 levels of primary colors which include the color red, blue, and green.
Color temperatures that are low tend to appear warmer as they have greater proportion of red wavelengths. Higher temperature colors however, have higher percentage of blue wavelengths, causing it to look cooler.
Measuring Color Temperature
So, how do we measure the color temperature of lights? We use degrees of Kelvin (K) – the values of light vary depending on the type of light.
White lights are neutral light with a measurement of 5400K. It is similar to the equal amounts of wavelengths of the colors red, green and blue. The cool color of the blue skies is at an estimation of 7500K. Whereas flames from candles produce warm lights that are about 1800K.
Why Is There A Need For White Balance?
Unlike our very own eyes that have the ability to naturally adjust light temperature to see light as white or neutral, our camera’s imaging sensor cannon do that.
Here’s where the White Balance feature come to the rescue. The DSLRs will be able to capture the authentic color as long as it is set correctly and can match the color temperature of the various types of light that fall onto your subject.
Setting Up The White Balance Feature
To ensure that your DSLR’s imaging sensor can match the various color temperature of lights is to use the White Balance feature. This function is present in all DSLRs which give you, the photographer the ability to choose the color temperature.
Do not be discouraged with the thought that managing the White Balance feature is tough to do. Digital cameras these days make it way easier to complement photography attempts. A vast majority come with the Auto White Balance feature which is at most situations very reliable.
