Kelvin Scale
Imagine you are out on a sunny day, capturing the stunning landscape with your camera. As you review the photos later, you notice that the color of the image doesn’t quite match what you saw in person. The blue sky appears too warm and yellowish, rather than the vibrant blue it actually was. This discrepancy in colors can be attributed to one important element in photography: white balance.
White balance refers to adjusting the colors captured by your camera to accurately represent the true colors of the scene. It ensures that whites appear as pure whites and all other colors are depicted faithfully. To understand how white balance works, we need to delve into the Kelvin Scale – a numerical representation of different color temperatures.
The Kelvin scale is named after William Thomson, 1st Baron Kelvin, who developed it during his research on thermodynamics. In photography, this scale is used to measure color temperature and categorize it based on warmth or coolness. Warm tones are represented by lower values (around 2000K-4000K), while cooler tones have higher values (around 5000K-10000K).
To better grasp the concept of color temperature, consider these real-world examples:
- A candle flame emits a warm light at approximately 1800K.
- Midday sunlight has a neutral tone at around 5500K.
- Overcast skies tend to result in cooler lighting conditions at about 7000K.
Understanding how various light sources affect color temperature is crucial for achieving accurate white balance in your photographs. Here’s an example bullet point list highlighting its significance:

You want to capture the true beauty of this moment, but how do you ensure that your camera accurately reproduces these colors? This is where understanding white balance becomes crucial.
White balance refers to the adjustment of colors in your photographs so that they appear neutral or natural under different lighting conditions. One way photographers achieve this is by using the Kelvin scale – a numerical system that measures color temperature. By adjusting the color temperature setting on their cameras, photographers can compensate for different types of lighting and maintain accurate color reproduction.
To better understand how white balance and the Kelvin scale work together, let’s consider an example: photographing a snowy landscape on a sunny day versus at dusk. In the first scenario, with bright sunlight illuminating the scene, selecting a higher color temperature (e.g., 6000K) would counteract any bluish tint caused by the snow reflecting blue skylight. On the other hand, during dusk when warm golden tones dominate the scene, choosing a lower color temperature (e.g., 3000K) would prevent those hues from appearing overly orange.
Here are some key points to keep in mind when working with white balance:
-
Different light sources have varying color temperatures. For instance:
- Incandescent bulbs emit warm yellowish light (~2700K).
- Daylight usually falls within a range of 5000K to 6500K.
