Understanding White Balance
Definition of White Balance
Before we delve into the relationship between white balance and colour temperature, let’s define what white balance is. White balance refers to the process of adjusting the colours in an image to ensure that white appears white and all other colours appear natural. When the white balance is off, the entire image can appear tinted in a particular colour, making it look unnatural and unappealing.
Relationship Between White Balance and Colour Temperature
White balance is closely related to colour temperature because it refers to the adjustment of colours based on the light source’s temperature. When the colour temperature of the light source changes, the white balance must also adjust to ensure that white appears white in the resulting image.
For example, if you take a photograph indoors under yellowish light, the image will appear to have a yellow tint, even though the objects in the scene are not yellow. To correct this, you need to adjust the white balance setting on your camera to remove the yellow cast and restore the natural colours of the scene.
Tips for Adjusting White Balance in Different Lighting Situations
Adjusting the white balance can make a significant difference in the quality of your photographs, particularly in different lighting situations. Here are some tips for adjusting the white balance in different lighting situations:
- In outdoor settings, choose a white balance setting that corresponds to the lighting conditions. For example, use “Daylight” for sunny days and “Cloudy” for overcast days.
- In indoor settings, choose a white balance setting that corresponds to the light source’s temperature. For example, use “Tungsten” for yellowish incandescent lights and “Fluorescent” for cool fluorescent lights.
- If your camera has a custom white balance feature, use it to adjust the white balance based on the specific lighting conditions.
- If all else fails, adjust the white balance in post-processing using editing software like Adobe Lightroom or Photoshop.
By understanding white balance and how it relates to colour temperature, you can ensure that your photographs accurately capture the colours of the scene and convey the intended mood or tone.

Common Myths About Colour Temperature
Colour temperature is often surrounded by various misconceptions and myths that can lead to poor lighting choices. In this section, we will debunk some of the most common myths about colour temperature and shed some light on the truth behind them.
Myth 1: All light bulbs with the same colour temperature look the same
This is a common misconception, and it couldn’t be further from the truth. Two light bulbs with the same colour temperature can look completely different due to the quality of light they emit. For example, a cheap LED bulb may have the same colour temperature as a high-quality incandescent bulb, but the LED bulb will emit harsh, unnatural light compared to the warm, natural light of the incandescent bulb.
Myth 2: Warm light is always better than cool light
While warm light may be more comfortable in certain environments, such as a bedroom or living room, it is not always the best choice. In some cases, such as in an office or a hospital, cooler light may be more appropriate as it can improve alertness and productivity.
Myth 3: The higher the colour temperature, the brighter the light
This is also a common misconception. The brightness of a light source is measured in lumens, not colour temperature. A high colour temperature does not necessarily mean a brighter light, and vice versa.
Myth 4: Colour temperature doesn’t matter in photography
This is a dangerous misconception, as colour temperature plays a significant role in the outcome of a photograph. Choosing the wrong colour temperature can result in inaccurate colours, loss of detail, and an overall unflattering image. It is essential to understand how colour temperature affects a photograph and how to adjust it accordingly.
By debunking these common myths, we hope to help you make more informed lighting choices and understand the importance of colour temperature in photography and lighting design.
