Have you ever wondered how you should set the white balance (WB) when shooting? In this article, I will explain how to use white balance by comparing photos taken with the WB set to Auto and Daylight.
Set the WB according to the desired colour tone instead of the weather
If you want to achieve a photo finishing that faithfully reproduces the colour tone that you see, you need to set the white balance (WB) to match the colour of the surrounding light. Sunlight changes in colour as time passes. It is bluish as the sun rises, but appears warm in the early morning and evening. Moreover, when shooting in the shade with no direct exposure to sunlight, blue light scattered in the blue sky shines on the subject, making its colour look colder.
For these reasons, when shooting in Daylight mode, the colour may not turn out the way you want when shot in the morning or evening or in the shade, although the colour finishing appears roughly as seen in the sun during the day. Therefore, when taking a picture with a preset WB, take note of how the light shines on the subject instead of the weather condition.
In the meantime, Auto White Balance (AWB) is more accurate and stable than Daylight mode, often reproducing colours more faithfully. However, a photo does not always need to capture colour tones faithfully. For example, when shooting in the shade on a clear day, while AWB can produce a good result by cancelling out the bluish tone of the subject, if an evening scene is shot in Auto mode, the reddish tone may be suppressed, resulting in a weaker impression.
To obtain a satisfactory colour tone, it is a good idea to either use the WB compensation function at the same time when shooting, or to first shoot the picture in RAW. You may wish to express the emotions you felt at the photographic scene with a variety of colour tones by changing the WB during RAW post-processing after shooting.
