A] White Balance
If the colours in a picture look squiffy, the chances are that it’s down to an incorrect White Balance. This is an adjustable setting that is designed to help you get the correct colour balance – including clean, cast-free whites – under a wide range of lighting conditions.
Light sources have a colour temperature that’s measured using the Kelvin scale, with light that is made up of predominantly orange and red being commonly referred to as ‘warm’, and light that is made up of blue known as ‘cool’. In the Auto White Balance setting, your camera works out what Kelvin value to set. It usually gives decent results in clear, ‘midday’ light, but can sometimes struggle in more extreme conditions and under artificial lighting. This is why there are a number of White Balance presets to choose from when you shoot in P, S, A and M modes; simply select the option that most closely matches the conditions you’re shooting in. You can also fine-tune the White Balance settings in the Shooting Menu to make resulting images appear warmer or cooler.
For the most accurate setting, you can create a custom White Balance by taking a picture of a white object in the same lighting conditions, which the camera will use as a guide to create a new preset. To be sure of coming back with a usable image, you can also use White Balance Bracketing, although this only works with JPEGs.
Shade WB When shooting during the ‘golden hour’, Auto White Balance will try to correct what it perceives as an orange colour cast (which is what you want!), and the result can be rather wishy-washy. To give additional warmth to the scene, ‘trick’ the camera by manually setting a White Balance preset with a higher Kelvin value, such as Cloudy or Shade
