White Balance

What is white balance?
White balance is a setting found on a lot of digital cameras, it enables you to calibrate the camera to the scene you are shooting so that it correctly displays the colour white. 

Light is made of up lots of different colours, and types of lighting are varied, e.g. indoor lighting might have a yellow tint to it, neon lighting might have a green tint. Different types of lighting will affect how the colour white is read by the camera. 

How do I change my white balance?
White balance (WB) often has an ‘automatic’ setting, so you don’t have to alter it manually. 

However, if you find that the colour white in your photos isn’t looking quite right, you usually have the option to alter this manually. If your camera gives you the option to do this, you can set it manually by going onto the WB setting, and choosing ‘custom’. Once you’ve chosen this option photograph a surface that is white, like a blank piece of paper. That way you’re telling the camera what the colour white looks like, and it will remember it when you are shooting.

Other options the WB setting often gives you is a selection of different scenes to choose from, e.g. ‘daylight’ or ‘indoors’. When you select one of these the camera will choose what it thinks is the optimum white balance for that environment.

What is the Kelvin Scale?
The kelvin scale (as represented by the 'K' icon in the image above) in the context of photography is a system to measure the temperature/hue of lighting. 

Previously I discussed how you can create a custom white balance, but another way of adjusting your white balance manually is to select 'K' and scroll through the numbers until the white colours you're seeing through the camera look the most accurate
