White Balance

White balance basically means colour balance. It is a function which gives the camera a reference to "true white" it tells the camera what the colour white looks like, so the camera will record it correctly. Since white light is the sum of all other colours, the camera will then display all colours correctly.Wehn filming at different times the light often changes,we may not see it but the cameras defiantly pick it up and so when filming if you manually correct the white balance it will allow all the video clips to be seen in similar lighting and the sunlight won't effect it.

You should perform this procedure at the beginning of every shoot, and every time the lighting conditions change. IYou will need a camera with a manual white-balance function. There should be a "white balance" button or switch on your camera.

1. If your camera has a filter wheel (or if you use add-on filters), make sure you are using the correct filter for the lighting conditions.
2. Point your camera to a pure white subject, so that most of what you're seeing in the viewfinder is white. One of the best ways of doing this is using a plain white piece of paper.
3. Set your exposure and focus.
4. Activate the white balance by pressing the button or throwing the switch. The camera may take a few seconds to complete the operation, after which you should get a message (or icon) in the viewfinder.
   Hopefully this will be telling you that the white balance has succeeded
   If the viewfinder message is that the white balance has failed, then you need to find out why. A good camera will give you a clue such as "colour temperature too high" (in which case change filters).

When changing the white balance you an also alter the colour by holding up say a blue piece of paper and the white balance will change the colour to an orange colour to help balance out the colours this is good as you can then create a warm and cold hue and mood when filming or taking photos.
