What is White Balance?
As a professional photographer, white balance is an essential concept that plays a crucial role in my work. It’s all about ensuring that colors in my photographs are rendered accurately, regardless of the lighting conditions. White balance is the process of adjusting the color balance in an image so that white objects appear true white, without any unwanted color casts. This, in turn, provides a neutral reference point for other colors in the scene.
When we’re out shooting, the color of light varies depending on the light source and time of day. Our eyes are remarkably adept at adjusting to these different lighting conditions, automatically compensating for color temperature shifts, allowing us to perceive colors consistently. However, digital cameras need a bit of help in this regard, which is where white balance comes into play.
By correctly setting the white balance, we can maintain the integrity of the colors in our images and create photographs that accurately represent the scene as it appeared to us. It’s not only about technical accuracy, though; white balance can also be manipulated creatively to enhance the mood or atmosphere in our photos, allowing us to express our unique artistic vision.
In-Camera White Balance
In-camera white balance is a powerful tool that helps us to capture images with accurate and consistent colors. Digital cameras perceive light differently from the human eye, as they use sensors to interpret the color temperature of the light source. To reproduce accurate colors, cameras need to know the color temperature of the light in the scene, which is where in-camera white balance settings come into play.
Most digital cameras come equipped with a range of white balance presets that are designed to work with specific lighting conditions. These presets compensate for the color temperature of the light source, ensuring that the colors in your images are rendered accurately. Some common in-camera white balance settings include:
- Auto White Balance (AWB): The camera automatically detects the color temperature of the light source and adjusts the white balance accordingly. This setting is suitable for many situations, but may not always yield perfect results.
- Daylight: Designed for shooting outdoors under natural sunlight, this setting compensates for the slightly cool color temperature of direct sunlight.
- Shade: When shooting in the shade, the color temperature is cooler than under direct sunlight. This preset warms up the colors to maintain accuracy.
- Cloudy: Similar to the shade setting, this preset warms up the colors to compensate for the cool color temperature of an overcast sky.
- Tungsten: Designed for shooting under tungsten or incandescent lighting, this setting cools down the colors to counteract the warm, orange hue of these light sources.
- Fluorescent: This preset is designed to neutralize the cool, greenish cast often associated with fluorescent lighting.
- Flash: When using an external flash, this setting compensates for the slightly cool color temperature of the flash to ensure accurate color reproduction.
In addition to these presets, many cameras also offer a custom white balance setting, which allows you to manually set the white balance using a reference object, such as a gray card or a color calibration target. This can be particularly helpful in situations where the in-camera presets may not provide optimal results, or when you’re working with mixed lighting conditions.
By understanding and utilizing the in-camera white balance settings, we can ensure that our photographs represent the scene accurately, both in terms of color and atmosphere. This mastery of in-camera white balance ultimately enables us to create high-quality images that meet the expectations of our clients and viewers.
Post-Processing White Balance
As professional photographers, it’s important to remember that capturing the perfect image doesn’t always end when we press the shutter button. Sometimes, despite our best efforts, the in-camera white balance settings may not deliver the most accurate color representation. In such cases, post-processing becomes an essential step in fine-tuning the white balance and achieving the desired color balance in our images.
Working with RAW files is highly recommended for post-processing white balance adjustments, as it provides the greatest flexibility and preserves the highest level of detail. Unlike JPEG files, which are already processed and compressed in-camera, RAW files contain all the unprocessed data captured by the camera sensor, making it easier to make adjustments without losing image quality.
Popular photo editing software, such as Adobe Lightroom and Photoshop, offer a range of tools specifically designed for white balance adjustments. These tools allow you to tweak the color temperature and tint of your images, either by selecting from a list of presets or using sliders to make precise adjustments. You can also use the eye-dropper tool to sample a neutral area in the image, which helps the software to calculate and apply the correct white balance automatically.
When adjusting white balance in post-processing, it’s important to strike a balance between technical accuracy and creative intent. While the goal is often to achieve true-to-life color representation, there may be instances where a slight color cast or deviation from accurate white balance enhances the mood or atmosphere of the image. In such cases, it’s up to us as artists to make deliberate choices that align with our vision and the message we want to convey through our photographs.
What is Color Temperature?
Color temperature is a vital concept in photography that helps us understand and describe the characteristics of various light sources. It is measured in Kelvin (K) and refers to the relative warmth or coolness of the light’s color. Color temperature is based on the principle of black-body radiation, where the hue of the light emitted by an ideal black body (an object that absorbs all radiation falling on it) changes as its temperature increases.
In practical terms, color temperature provides a way to categorize the colors of light sources. Lower color temperatures (around 1,000-3,000K) are associated with warmer, more reddish-orange hues, which are typical of incandescent bulbs, candles, and sunrise or sunset light. On the other hand, higher color temperatures (5,000-10,000K) correspond to cooler, bluish hues found in daylight, overcast skies, and shade.
Understanding color temperature is essential for photographers, as it allows us to predict how different light sources will affect the colors in our photographs. By considering the color temperature of the ambient light or any artificial light sources we use, we can make informed decisions about white balance settings and adjustments, ensuring accurate color representation in our images.
The Relationship Between Color Temperature and White Balance
Understanding the relationship between color temperature and white balance is crucial for photographers, as it enables us to make informed decisions about how to capture images with accurate and consistent colors. Color temperature describes the color characteristics of a light source, while white balance is the process of adjusting the colors in a photograph to neutralize any color cast caused by the light source.
When we take a photograph, the light source’s color temperature directly impacts the colors in the image. Depending on the light source, the colors in the scene may appear warmer (more orange) or cooler (more blue) than they would under neutral lighting conditions. Our eyes are remarkably good at adapting to these variations in color temperature, allowing us to perceive colors consistently across different lighting conditions. Digital cameras, on the other hand, require assistance to adjust for the color temperature of the light source, which is where white balance comes into play.
White balance compensates for the color temperature of the light source by adding or subtracting color in the opposite direction on the color temperature scale. For example, if the light source has a warm color temperature (e.g., incandescent bulbs), the white balance setting will add cooler colors (blue) to the image to neutralize the warm color cast. Conversely, if the light source has a cool color temperature (e.g., shade or overcast sky), the white balance setting will add warmer colors (orange) to counteract the cool color cast.
By understanding the relationship between color temperature and white balance, we can make informed choices about which white balance settings to use in various lighting situations. This helps us achieve accurate color representation in our images, ensuring that the colors appear true to life and consistent across different shooting conditions. Furthermore, mastering the connection between color temperature and white balance empowers us as photographers to manipulate these settings creatively, enhancing the mood and atmosphere in our photographs to align with our artistic vision.
In essence, the relationship between color temperature and white balance is a fundamental aspect of photography that plays a critical role in capturing images with accurate and consistent colors. By mastering this relationship, we can produce high-quality images that resonate with our clients and viewers and convey our creative intent effectively.

White Balance Scenarios
Best White Balance for Cloudy Day
For cloudy days, a white balance setting between 6000K and 6500K is generally recommended. This range of color temperatures helps to compensate for the cool and diffused light characteristic of overcast conditions. By adjusting the white balance to this range, you can effectively neutralize the bluish color cast that often occurs under cloudy skies, resulting in more accurate and natural-looking colors in your photographs.
Best White Balance for Sunny Day
For sunny days, a white balance setting between 5400K and 5500K is generally recommended. This range of color temperatures corresponds closely to the color temperature of direct sunlight, which typically falls between 5200K and 5600K. By adjusting the white balance to this range, you can effectively maintain accurate and natural-looking colors in your photographs.
Best White Balance for Mixed Lighting
In situations with mixed lighting, where multiple light sources with different color temperatures are present, determining the ideal white balance can be challenging. Since there isn’t a one-size-fits-all solution for mixed lighting, using a custom white balance is often the best approach to achieve accurate colors in your photographs.
To set a custom white balance in mixed lighting conditions, follow these steps:
- Find a neutral reference point: Look for a gray or white object within the scene that is illuminated by the mixed light sources. This could be a gray card, a white piece of paper, or even a neutral-colored surface.
- Capture a reference image: Take a photo of the neutral reference object with your camera, ensuring it fills a significant portion of the frame and is correctly exposed.
- Set custom white balance: Refer to your camera’s manual for specific instructions on how to set a custom white balance using the reference image. Generally, this involves selecting the “Custom White Balance” option in the camera menu, choosing the reference image, and confirming the new white balance setting.
By setting a custom white balance based on a neutral reference point within the scene, your camera will effectively average out the color temperatures of the mixed light sources, resulting in a more accurate and balanced color representation in your photographs.
Best White Balance for Sunset/Sunrise
During sunset and sunrise, the light is often characterized by warm, golden hues that contribute to the unique atmosphere of these moments. While using Auto White Balance (AWB) can sometimes yield satisfactory results, it may not always capture the true essence of the warm and vibrant colors present during these times.
In AWB mode, your camera will analyze the scene and try to neutralize the color cast by adjusting the white balance automatically. However, this might result in an image that looks too cool and does not convey the warm and magical quality of the sunset or sunrise.
Best White Balance for Indoor Photography
In indoor photography, the most suitable white balance setting largely depends on the specific lighting conditions you’re working with. Many indoor environments use artificial lighting, such as tungsten or fluorescent lights, which can have different color temperatures and result in varying color casts.
For environments lit primarily by tungsten or incandescent bulbs, which are common in residential and some commercial spaces, setting your white balance to 3200K is a good starting point. This color temperature helps to counteract the warm, yellowish-orange hue these light sources typically produce, resulting in a more accurate and natural color representation in your photographs.
