Since camera technology entered the market, new ways of photographing have emerged and, with it, more practicality and elegance in clicks and image making.
In other areas, we have already talked about the importance of colors, their temperatures and the challenges of photographing without this knowledge, so in this new article we will talk and focus even more on the theme of color balance and other associations so that the photo has the quality it deserves.
Today you will learn more about

White balance is a function used to compensate for color tone defects, generated by other light sources. An exact white color is considered an appropriate shade of standard color and can be generated when photographed in a light source with approximately 5500k and balanced colors of green, red, and blue.
On the other hand, the white appears reddish if it is under an incandescent bulb, whose temperature will be about 3000k, at this temperature the red element will prevail and the white will appear bluish if it is under a fluorescent light, whose color temperature will be about 6500k.
In this case, the blue element will prevail over these two light sources. The results of the photo shoot will depend on the hue, balance and temperature and light sources. Therefore, it is possible to adjust the white balance in the cameras using the following methods:
This balance is very important, because when you use it correctly, the photo is sharper and more quality, reaching 100% of the actual color value of the images. When the white balance is not set, the image tends to turn bluish.
See the images below
In the first photo, it is possible to notice that the color balance is incorrect and in the second image, the scale found the scale on this scale.
The white balance process eliminates unreal colors, that is, it even creates objects that are not white and leaves them in that tone, because that’s exactly how our eyes see these objects.
The photographer must understand that to get a perfect white balance in the photos, it is necessary to take into account the color temperature of a light source.
Our eyes, vision and brain work together and are very well trained to see different colors, be they cooler or warmer colors. As a result, we can easily perceive white color, but digital cameras usually have trouble adjusting auto-white (“Auto White Balance” or “AWB”).
Therefore, an incorrectly performed white balance will involve so-called “washed” images, i. e. they can have blue, orange, red, and even green tones. It would be a bad result for the photos.
In this case, what will the photographer need?
To make a perfect adjustment of the white balance for traditional photography, it would be necessary to use certain filters or films so that the lighting conditions that vary in intensity and brightness are differentiated by the camera.
Fortunately, this won’t be necessary in digital cameras, which are much more modern and versatile.
And that’s where understanding how this white balance happens becomes essential to help you avoid unwanted tones in photos that are generated by the camera’s own ABW.
In this way, it will be possible to improve the quality of photos on a large scale, depending on the lighting conditions.
Automatic white balance
Some photographers create problems with the camera’s automatic white balance. Many professionals experience this difficulty, with warmer or cooler colors, especially when there is an abundance of elements.
In the images below, you will see that there is a predominance in red, this is because the digital camera understands that this element has an improper predominance, which is caused by a warmer light source.
So, what’s going on?
The camera tries to compensate so that the average color is closer to that of a neutral tone and, in doing so, inserts the bluish color into the stones under the leaves.
It should be noted that some digital cameras are more likely to do this than others.
Then, in the first photo, you will see that the white balance was done automatically and in the second image, the scale was customized, so that the stones acquire their original color.
In the second photo, the custom balance was used with an 18% gray card and as a neutral reference.
An interesting fact about this is that the automatic white balance of a digital camera will be more effective when the photo contains at least 1 white element.
But it should also be noted that the photographer should not change the composition so that only one white element remains in the frame, as this can cause problems with automatic balancing and therefore damage the automatic white balance of his camera.
There are those who think that these tips are irrelevant, but when viewing this content and the possibility to compare one image in bluish tone and another in exact white, we can conclude that to learn more about colors, light sources, warm and cold colors and automatic and personalized balance, it makes the difference for a professional job!
