Definition of White Balance
White balance (WB) is an element in photography and video that allows colours to be adjusted to be as close as possible to how they are perceived by the human eye in real life, as an initial assumption. How the camera interprets white light in different lighting conditions significantly affects the final appearance of a photograph.
White Balance Camera
Cameras use algorithms to analyse the scene and adjust the balance so that the white elements in the photo are actually white, which affects all other colours. This setting can be done automatically by the camera (Auto white balance) or manually, especially in difficult lighting conditions such as shadow, incandescent light or fluorescent light.
However, today’s editing technologies also allow for effective white balance correction at the post-production level. With programmes like Adobe Photoshop, photographers can fine-tune the white balance on the big screen, often achieving more accurate and satisfactory results than adjusting during the shoot itself.
Effect of White Balance on Colour Perception
For example, a photo taken indoors in artificial lighting without white balance correction often shows a yellow or orange glow, which can be undesirable. Making the appropriate correction in or post-production can change this photo, making the colours more natural and closer to those we see with the naked eye.
We can correct the white balance both during the taking of the photo and after it has been taken in post-production.
Although the initial white balance setting in the camera matters, editing allows us to fine-tune and correct photos with great efficiency.
Methods of White Balance Adjustment in Practice
Shooting with manual white balance settings allows you to adapt to specific light conditions on location. Manual settings are particularly useful in controlled conditions where the photographer has time to experiment and evaluate the results. For example, in difficult lighting conditions such as mixed light sources (natural and artificial), manual white balance adjustment can prevent unwanted skin tones or other elements in the scene.
On the other hand, the flexibility of RAW files in post-production is invaluable. By shooting in this format, it is possible to make much more precise white balance adjustments later in the studio without fear of losing the quality of the image. Photo editing software allows you not only to change the colour temperature, but also to subtly adjust the tones, which can dramatically improve the aesthetics of a photo.

White Balance and the Final Appearance of Photos
White balance does not just affect the colour white, but all colours. Incorrect settings can lead to photos that appear unnaturally cool (too blue) or warm (too yellow), which can disrupt the intended artistic or emotional effect of the photo. Therefore, even though white balance can be corrected in post-production, it is worth taking the time to learn and experiment with different settings directly in camera.
Modern tools and techniques allow a great deal of freedom in correction, both at the shooting stage and in post-production. This gives more control over the final look of their work, enabling them to accurately render the intended visual effects.
The Importance of White Balance
While it is possible to correct temperature both during shooting and in post-production, it is worth understanding its fundamental importance to the quality of the final image. Focusing on taking a good photo from the outset also includes considering the right white balance, which affects the naturalness and aesthetics of the photo.
Effect of White Balance on Colour Perception
White balance is crucial to the perception of colours in a photograph. Photos with a properly set white balance reflect the true colours of the scene, which is particularly important in portrait and landscape photography. For example, an incorrect temperature can make the skin in portraits appear unnaturally yellow or blue, which significantly reduces the aesthetic quality of the photo.
White Balance Options
Understanding the different methods of white balance adjustment is crucial for any photographer, whether amateur or professional. Choosing the right method depends on many factors, including lighting conditions and the desired aesthetic effect.
Automatic White Balance – Advantages and Limitations
Automatic white balance (AWB) is the most commonly used setting on cameras. It is particularly useful in dynamically changing light conditions, where quick adjustment of settings is crucial.
AWB uses algorithms that analyse the scene and automatically adjusts the white balance to make colours as natural as possible. However, in extreme lighting conditions such as mixed light, AWB may not always interpret the scene correctly, which can lead to unnatural shades, especially in shadows and highlights.
Manual White Balance Setting – When to Use It
Manual white balance setting gives the photographer full control over the interpretation of colours in the image. This is particularly useful in controlled environments, such as a photographic studio, where the lighting is constant and predictable. For example, shooting in a studio with artificial light sources often requires manual adjustment of the white balance to achieve the desired colour effects. Manual settings allow experimentation with different colour temperatures, which can significantly affect the mood and atmosphere of a photograph.
When shooting in a variety of conditions, it’s a good idea to use white balance grey card balance with you to help calibrate your camera. Using a white balance card when you first set up a scene allows you to accurately balance the white, which is particularly helpful when lighting conditions change or when moving between different locations.
WB can be an artistic tool that allows photographers to express their vision. Knowing and being able to use different methods of adjusting the balance can add depth or naturalness to photographs, regardless of the lighting conditions.
White Balance in Different Conditions
Understanding the effects of different lighting conditions on white balance is essential for any photographer to be able to manipulate colours effectively and produce images of the highest quality.
White Balance Daylight
Daylight, although considered ideal due to its naturalness, can also bring challenges, especially at midday when it is most intense. Photos taken in the midday sun without correction can appear too sharp with high contrast. Using the ‘daylight‘ white balance setting helps to neutralise excessive blue skies, preserving natural skin tones and environments.
When shooting outside on a cloudless day, set the white balance to ‘daylight’ (approx. 5500 K) for natural colours.
Adapting to Artificial Lighting
Shooting indoors with artificial lighting, such as incandescent or fluorescent light, requires specific white balance settings to avoid the dominance of yellow and green tones. For example, setting the WB to ‘incandescent‘ helps to reduce the yellow tones of incandescent light, giving the photo a more natural look.
When shooting indoors with incandescent light, set ‘incandescent’ (approx. 3000 K) to neutralise the yellow tones.
Shooting in Mixed Light Conditions
One of the biggest challenges for photographers is shooting in environments where there is more than one light source – for example, natural and artificial. In these situations, setting the white balance manually allows for a more precise adjustment to the prevailing conditions, which is crucial, for example in wedding photography, where different light sources may be present simultaneously in one location.
Knowing how different types of light affect a photograph allows photographers to choose the right white balance settings, which is key to achieving the desired visual effects. This skill is particularly important in professional photography, where expectations of photo quality and aesthetics are very high. By properly managing white balance in different lighting conditions, you can not only avoid common mistakes, but also experiment with the mood and atmosphere of your photos.
Tools and Equipment for Controlling White Balance
The availability of white balance tools and equipment enables photographers to precisely manage the colours in their images. Understanding how and when to use these tools is essential for the best results.
White Balance Grey Card
White balance grey card is one of the primary tools used by photographers to calibrate colours on camera. These cards, usually made of a durable, neutral grey material, help to set the white balance before the shoot begins. The user sets the card in the light in which the images will be taken, and the camera uses it as a reference point for colour correction. This is particularly useful in the studio or in difficult lighting conditions, where accurate colour reproduction is crucial.
When working in mixed lighting conditions, use a white balance card and manually adjust the white balance for more accurate colour reproduction.
The Impact of Post-Production on the Final White Balance Result
Post-production offers advanced correction tools that can significantly improve the quality of your photos, especially when the images were shot in RAW. Programs such as Adobe Lightroom and Photoshop allow fine-tuning of colour temperature and hue, enabling corrections that can completely change the character of a photo. Even minor adjustments in post-production can bring greater depth and realistic colour reproduction to photos.
Errors in Setting the White Balance
Although in photography every element can be interpreted as part of the artistic vision, some ‘mistakes’ in setting the white balance can unconsciously affect the perception and quality of the image. Consciously making decisions about WB allows you to have full control over the visual effect of the photograph.
One common mistake is over-reliance on automatic white balance, which can inadequately interpret specific lighting conditions.

For example, photos taken in the shade using AWB often show a bluish tint that can give the impression of being cold and offset. Another common problem is an incorrect white balance setting in mixed light source conditions, leading to photos with unnatural skin colours or an incorrect rendering of the environment.
Photographers should learn to observe lighting conditions and experiment with different white balance settings on their cameras. Practising with a white balance card or taking test shots before the actual shoot are effective ways to ensure that the WB matches the actual conditions. It is important to always check the appearance of your images on the camera screen and not just rely on visual impressions.
As we draw this article to a close, it’s essential to acknowledge that achieving a precise white balance in the camera is the foundation for photography that conveys true-to-life colors.
Whether you are shooting in the enveloping glow of daylight or under the sterile fluorescence of indoor lighting, understanding your white balance options can transform your images from amateur snapshots to professional-grade representations.
Should you find yourself needing to fine-tune those white settings post-shoot, a white balance adjustment Photoshop can be a game-changer, allowing for pixel-perfect correction. Always remember, tools like a white balance grey card are indispensable for nailing that perfect shot in-camera, saving you valuable time in post-production and ensuring that your photos look exceptional, no matter the light source.
