Automatic White Balance (AWB). In automatic white balance mode the camera looks at the overall color of the image and calculates the best white balance setting. While the automatic white balance mode often works, it can make mistakes.

 


Automatic white balance - An HP Real Life technology that automatically adjusts white balance (the colour of light) to create an image as you would see it. Also known as Adaptive colour balance.

Automatic white balance compensation.
The colour temperature of a flash tube can vary subtly depending on its precise voltage.

Automatic White Balance compensates for different colour light sources, e.g. daylight, tungsten light, fluorescent light etc..

Automatic white balance performance is very good on this camera, but for best results a number of presets are available: daylight, cloudy, shade, flash and halogen, ...

Automatic white balance is generally pretty decent. The problem with it is that the camera must guess. It has no way of knowing for certain the kind of subject being photographed nor the kind of light shining on the scene.

The automatic white balance system gives great results, and the metering system is all but infallible in most conditions, apart from a slight tendency to overexpose fractionally in very bright conditions.

AWB (automatic white balance) is the default setting and the one you should use most of the time. Daylight, shade, cloud, flash and tungsten are all fixed settings that you can use under the appropriate lighting conditions.

Automatic White Balance: There are literally dozens of research projects on creating accurate white balance automatically. None of them are perfect, but they are getting better.

AWB - Automatic White Balance. A system for automatically setting the white balance in today's digital cameras. See also "White Balance"

Turn Off Automatic White Balance
In many photographic situations white balance is a godsend. By automatically neutralizing extreme color casts, believable digital color is rendered without breaking a sweat.

Although automatic white balance does a good job under most conditions, you can manually set your own white balance for better results. This is like using different types of film in 35mm photography.

Digital cameras may have the feature of automatic white balance so that the camera looks at the overall color of the image and find a white balance. However, if we take a photograph dominated by one color, the white balance will not be accurate.

Different light sources can confuse the automatic white balance of your camera.
If your camera supports RAW, you can record RAW and fine tune the white balance during the development process.

Most digital cameras have a means to select a color correction based on the type of scene illumination, using either manual illuminant selection, or automatic white balance (AWB), or custom white balance.

Some cameras come with built in automatic white balance correction. You can also adjust the color balance in an image editing software. The colors are divided into three pairs: Cyan and Red; Magenta and Green; and Yellow and Blue.

This is when the automatic white balance (or color balance) is needed. To work correctly, a bright, very white surface is necessary in the frame. If this is missing, the automatic function has no comparative value.

So, lets say, for instance you photograph a wedding, and return home with a slight color cast on your images because the camera's automatic white balance was fooled by mixed light sources in the church.

I've heard conflicting recommendations on where to set the white balance on my digital camera. Some sources advise the use of automatic white balance; others say to use a different white-balance setting for each specific light source.

Digital cameras usually enable the user to adjust for ambient light conditions using a white balance feature. Most cameras have an automatic white balance mode for daylight, cloudy, tungsten or fluorescent lighting.

White-balance settings can be changed within the digital camera to adjust for sun, shade, tungsten and fluorescent lighting; automatic white balance is also an option, although accuracy is generally inconsistent.

After considering cost and resolution, exposure control is the next big decision when purchasing a digital camera. How much manual control do you want? Is automatic white balance important? And does film speed matter in a film-less camera?

As you can see by the interactive example below, white balance also effects other colors as well. If your camera's automatic white balance setting doesn't get the color 'white' correct, it won't render the other colors correctly either.

If you're more experienced using white balance, play around with it a little (experimenting with it will improve your experience anyway). Some people prefer incandescent while others are happy to rely on the automatic white balance (AWB).[1] ...

Without correction, a picture taken at sunset can seem too yellow or orange and a picture taken under fluorescent lights might seem too green. Some cameras come with built in automatic white balance correction.

Most digital cameras feature automatic white balance, this means that the camera looks at the overall colour of the image and calculates the best-fit white balance, ...

Digital sensors also have intrinsic UV sensitivity and can also suffer from UV effects, though in the case of digital it's relatively easy to make post exposure color corrections, plus the Automatic White Balance function (if in use) may make ...

Automatic white balance. Because the color in a photograph is affected by the color of the light illuminating the scene, ...
