George Cairns explains how to remove colour casts using Capture NX-D
Discover how Nikon Capture NX-D can help you alter your white balance setting to remove unwanted colour casts
If two photographers shoot the same scene at the same time with identical cameras, the colours in the resulting photos can
look quite different. One camera’s shots might feature a cool, blue colour cast, while the other camera could capture warmer-looking colours. These discrepancies in colour can occur because different white balance settings were used.
Your Nikon has a range of white balance presets to help it deal with the different colour temperatures produced by various light sources. Daylight has an average colour temperature of 5000 degrees K, for example, while light from an incandescent bulb has a lower colour temperature of around 3000K. Confusingly, lower-colour-temperature light sources produce warmer colour casts, while higher temperatures produce colder ones. Your Nikon’s white balance settings are designed to counter these tints and produce accurate colours.
White balance presets
You camera’s Auto White Balance (AWB) setting will analyse whites or greys in different lighting conditions, and warm them up or cool them down as necessary. Sometimes the AWB setting won’t succeed, and you’ll end up with cold-looking landscapes, or indoor portraits in which skin tones appear too orange. Choosing an in-camera white balance preset can give better results – selecting Direct Sunlight, for example, tells the camera that the colour temperature of the ambient light is close to a cool 5500K, so it will warm up your shots accordingly.
Choosing in-camera white balance settings manually can be timeconsuming, so you may prefer to stick to AWB. And as long as you shoot RAW, Capture NX-D enables you to select a different white balance setting post-shoot, so you can banish colour casts with ease.
