Customise colour reproduction

LEARN HOW TO CREATE A CUSTOM WHITE BALANCE PRESET IN-CAMERA AND SHOOT IMAGES WITH ACCURATE, TRUE-TO-LIFE COLOUR

ONE OF THE biggest advantages offered by digital photography is the ability to adapt the camera to changeable lighting. In analogue days, should the colour balance of the ambient light change, the film type would have to be swapped to compensate, wasting the remaining frames. In the majority of cases, a white balance preset can be chosen from the camera menu, which will quickly adjust the colour bias to prevent strong casts. However, these presets are designed to cater for average lighting under usual conditions, and hence may lack absolute accuracy.

Therefore, in order to produce the most print-ready file possible, a custom white balance can be created for the current shooting environment. This is especially useful when shooting in JPEG format, when there is a requirement for large buffer capacity for example, since colour cannot be altered non-destructively, unlike with RAW files.

Using a standard white balance target, which is usually white or 18% grey, the camera is able to calculate a colour temperature that best represents the hues present in the scene, tailoring reproduction to the lighting that exists on a real-time basis. This improves colour fidelity, which can make a big difference when attempting to render natural tones in outdoor, interior or studio settings alike.

USE A WHITE BALANCE PRESET

01 It is always useful to try implementing a preset white balance (WB), especially in new environments, to see if any are appropriate without customisation. This may be possible under simple lighting.

SHOOT A REFERENCE TARGET

02 In mixed or studio lighting, where colour bias is obvious, hold a WB target so that it fills the frame and shoot using any preset. Prevent strong lighting falling on the target to avoid overexposure. 03 Enter the menu, navigate to the WB options and choose an image containing the target from which the camera can derive a reference colour balance. Choose the image that best represents light intensity.

CHOOSE CUSTOM PRESET

04 Once your custom WB has been defined and saved, use the command dial to select that preset name from the WB options. Be sure to choose the preset you just made, to guarantee colour accuracy.

SHOOT A TEST IMAGE

05 Now take a test shot to see if you are happy with the colour balance suggested. If there is an obvious bias, try reshooting the target, ensuring it fills the frame and is evenly lit.

FINE-TUNE TINT

06 For small colour shifts, further customise the colour balance using the fine-tune screen, if your camera model has this functionality. Make small tweaks and shoot another test.
