Color—it all seems so simple. We take a picture, the color looks great… if we have the perfect white balance.
How often have you returned home, uploaded images and thought, ‘Hmm I am sure that sunset was more golden’? Or ‘this snow was much whiter’?
We’re going to look at the first stage of that equation. This article is all about what is white balance in photography. And how to understand white balance in four simple steps.
What Is White Balance in Photography?
The way our eyes see color is very different from the way our digital devices decode it. Add to that the fact that different devices interpret color in different ways.
There is huge potential for your images to look wrong when you get them up on screen. But there is a system photographers use to get color right. From the camera to the final image.
It’s called color management. It involves camera settings, colors in your post-production software and monitor calibration.
All light has a color and that color is itself a temperature. The color temperature scale used for light is the Kelvin Scale.
At the lower end of the scale, 2000-4000k shows warm light of reddish yellows. At around 5500k, the color is pretty much what we see at noon on a sunny day.
As the scale climbs, the light gets progressively bluer. At about 10,000 K we reach the very blue light of a typical flash gun.
Our cameras have a sensor that determines what the color cast of the light is. We can let that sensor to select the right camera white balance. We do this by using the AWB (auto white balance) setting.
For the most part, this sensor is very accurate. But a large block of a single color can fool it. For example, a woman wearing a bright red dress.
In this case, the color sensor will see the image as being redder than it actually is. And it will overcompensate by turning the image bluer.
This is often what happens with those wonderful sunset pictures. The overabundance of red light fools the camera sensor into adding more blue. This neutralises the scene.
The results you would see by setting your white balance to these specific presets
4. How Do I Deal With Camera White Balance?
Modern digital cameras give you the option to change the white balance manually. You also have the auto white balance (AWB) option.
AWB is often suitable for daylight situations. In most other situations, it’s guessing what the balance should be. The most common example for this is when shooting indoors in tungsten light.
Canon, in particular, are bad at getting the color right on Auto mode. It can often come out far too warm.
Custom: This is for setting the photography white balance accurately using a grey card. More about this in section 3.
These modes tell your camera how much it should adjust the color of the photo it’s taking.
To show how these modes affect the temperature of an image, check out the photo below. The model had the sun setting behind her.
In a typical digital SLR these are the white balance settings you can choose from:
Auto: Good if you don’t know what you’re doing. It works well in sunlight but is unsuitable for most situations.
Photo comes out quite cold.
Daylight: Auto mode can be good in daylight but not perfect. I would use this balance in daylight.
Most people tend to stick to auto. It’s because they’re worried about forgetting to change the White Balance when they go back indoors.
Not bad, but the camera is trying to compensate for a much brighter environment. It’s overcompensating.
Shade: Auto mode makes photos look a little cold in the shade. Using this preset will be a lot more accurate.
Very accurate, it captures the spring evening perfectly.
Cloudy: Again, this is pretty self-explanatory.
Very good but still a little colder than the environment actually was. This setting is for much warmer light
Tungsten: This light comes from incandescent bulbs found in your home. Left on auto, your photos will come out very warm with an almost orange color cast in this environment.
Fluorescent: This comes from tube lighting conditions found in offices and hospitals. It’s a very cold light and can make your photos appear blue. This is also why offices have that nasty sterile feel.
Far too cold. This setting is for much warmer light and , as you can see, cooled the photo accordingly.
Flash: This compensates for the somewhat cool light of the camera’s flash.
Worked surprisingly well. It’s more accurate than auto mode for this sort of lighting.
You’ll see that the ‘Shade’ setting is most accurate for that situation.
3. How Do I Change My Camera White Balance?
There is no exact answer to this, hence I have left it to the end. It very much depends on the maker of your camera and the model.
Using the principles in this article, you should be able to adjust the settings on your camera. In doing so, you achieve the right white balance photography.
Professional-level cameras often have direct access to white presets. And manual white balance photography. This happens through buttons and dials on the body itself.
On lower level cameras you may well find that presets can be set from the body.
But the manual settings will be buried in the menu system. More often than not in the shooting settings.
My best advice here is to experiment with different white balances on some non-essential shoots.
As with many things in photography, the more you expose yourself to their use, the more natural they will become to you.
Setting a perfect white balance photo and understanding different color temperature is an important part of the photographic process.
I would say that after mastered the exposure triangle, mastering camera white balance photography should be your next stop. As you can see, the white balance definition is easy to understand.
It’s about understanding how the color of light effects the way your image looks. By dictating the photography white balance you can set the mood and feel of an image. Auto won’t do this for you.
Set Manual In-Camera White Balance Settings
Now you’re armed with an understanding of the color of light and its temperature. You can set degrees K to get a perfect white balance photography.
Not all tungsten lights, for example, give out the same color temperature.
If you are shooting under one that is less red, you can increase the color temperature. Try going from the preset 2500 K to 2800 K to get a more natural look.
You can experiment with different color temperature to get the best look for your image.
Custom and temperature create the most accurate camera white balance photography. First though, you need to learn about grey cards.
Grey cards determine which white balance settings your camera should use. They are 18% grey; a neutral hue.
To use grey cards, take a photo of the card so that it fills the whole frame of your camera. Then set this as the white balance inside your camera.
The camera sees the difference between the result and the neutral hue. It determines the balance from that.
The reason you’d use a grey card and not a white one is simple. If you overexpose any color enough, it’ll come out as white. White balance is about color, not brightness.
You took the grey photo in the same lighting environment as the rest of your photos. So the camera knows exactly how much to adjust the balance.
Custom: This is where you would take the photo of the grey card and set it in your white balance settings. All cameras are different so I recommend looking in your manual to check how to do this.
This is the most accurate way possible to capture color on the cheap and I fully recommend it.
Color Temperature / Kelvin: This is for professional photographers setting the white balance value themselves. The value is in Kelvin (K) – named after the man who created the scale.
For example, sunlight is approximately 5200 K. Tungsten is approximately 3200 K.
Use White Balance Photo Presets
All modern digital cameras not only have Auto White Balance settings but also have a number of presets. The include Tungsten lights, Fluorescent lights, Daylight, Shade, Cloudy and Flash.
If you find that a deep, overcast day gives you too much blue, switch to ‘Shade’ or ‘Cloudy’. These should warm your image up.
If you are shooting under tungsten light using AWB, switch to ‘Tungsten’. This will balance out your color temperature.
You don’t have to use a specific preset for a specific light. A classic way to maintain the saturation of sunsets is to set the Shade or Cloudy preset. This adds extra warmth to the image and keeps that sunset looking real.
Presets are a quick and simple solution to getting good white balance photography. But they are not always perfect.
By using the shade preset the saturation is much better in this sunset shot
Creating Your Own White Balance Settings
The color sensors in our cameras read the light reflected back from our scene. But it can get confused by large blocks of color.
There is a technique that can give us perfect white balance photography. You just have to carry a piece of white card.
By placing the white card in front of your camera you are reflecting back the pure untainted light.
This light information can be stored as a preset. As long as the light source does not change too much. Then it will give you correct and consistent white balance.
1. Which Setting Is Best for Me?
You have 5 options:
1 – Spend all your time shooting on auto mode and hope for the best. This is alright if you’re still trying to get to grips with exposure but after that I recommend you move on.
2 – Try to produce accurate results using the preset modes inside of your camera. This is a step in the right direction. But they’re still ballpark figures and won’t always produce 100% correct results.
3 – Shoot in custom white balance mode. This is the most popular choice by professional photographers. It can have a learning curve and requires carrying around a grey card.
4 – Use a light temperature meter. This is a very accurate solution but can cost a lot of money. It’s not a realistic option for most.
5 – Shoot in RAW. For those of you who don’t know, RAW is an uncompressed file format. It allows you to change things on a computer after you’ve taken a photo.
One of these things is the white balance.
Many of you already shoot RAW. One of the reasons that you do so is because you can manually set white balance in post-production.
When you shoot a RAW file, white balance is measured and applied as a reference. But you can change this in Adobe RAW, Lightroom or any other RAW processing software.
There is an issue here though. If you shoot only RAW, you have no real reference how the light was in the original scene. You only see the camera’s interpretation of it.
A better option is to to use one of the techniques above when shooting RAW. Presets, manual white balance or creating your own white balance settings.
You give yourself a more accurate base white balance reading to use in your post production.
Using RAW gives you full control over white balance but it is still good practice to set the balance yourself
