White Balance Introduction :

It sounds complicated to most people but it really is not.White balance is measured in kelvins and actually measures the colour temperature, in other words how warm the light is, we may have 3200k up to 8000kWhen we look at a white object our eyes will automatically adjust to the lighting conditions, so that the object appears perfectly white to us whether we are indoors under a tungsten bulb or out in the bright sunlight.While our eyes are excellent at making this adjustment, digital cameras are not and the same object will appear different depending on the colour of light in the scene (the colour temperature) this can leave our photos with a blue (cool) or orange (warm) tint.White balance is the process of giving our camera a helping hand, so that it can reproduce the whites in our photo as they should be. Once it gets the white right, all the other colours in the scene fall into place and we’re left with an image that perfectly reproduces what our eyes saw.

White Balance Settings :

Typical white balance settings include Daylight, Shade, Cloudy, Tungsten, Fluorescent and Flash, these work exactly as you would expect, you simply choose the appropriate setting for your shooting conditions and the camera will do the hard work of making white objects appear white.

Auto White Balance :

Auto white balance is usually very good on a nice bright sunny day, it’s not so good when it’s overcast or the scene is in shade, at times like this we may need to set the white balance to a cloudy or shade setting to warm the scene up, likewise under artificial light we may need to use a tungsten or incandescent setting.

 Custom White Balance :

For situations where the white balance settings will not do, most cameras also come with a Custom White Balance setting, in this mode we begin by taking a photo of a white object (a sheet of white paper or a professional white balance card) under the lighting conditions of our scene, then we tell our camera to use that image as its white balance reference & then all photos taken under those conditions will come out correctly balanced. This setting is great in a studio or even if we are selling items regularly on ebay as once we have the setting all photos we take come out with the same colour temperature.

Using The Wrong White Balance Setting : 

USING THE WRONG WHITE BALANCE ON PURPOSE Most of the time we will want the colours of our scene to be rendered as accurately as possible, but sometimes we can get a more impressive image by artificially warming up or cooling down the scene. To artificially warm up a sunset we can select one of the cooler white balance settings, such as Cloudy or Shade, this will enhance the warm reds and oranges in the photo and subdue the cold blues and greens leaving us with a much more pleasing image.
