For photographers, white balance will be one of many trickiest ideas to grasp. And even when you perceive the fundamentals, deciding on the precise white steadiness setting is overwhelming. Your digicam doubtless boasts an array of choices, together with white steadiness presets (e.g., Daylight, Cloudy, Tungsten) and handbook Kelvin values.
However your digicam doubtless provides one other setting: Auto White Steadiness, or AWB.
Auto White Steadiness actually sounds interesting – in keeping with its title, when you set your digicam to its AWB setting, it’ll routinely select a white steadiness for the scene – however how good is AWB, actually? Must you belief it when capturing within the discipline, or do you have to work with a unique setting as an alternative, even when it takes extra effort?
That’s what I goal to reply on this article. Beneath, I clarify what Auto White Steadiness is; I additionally discover its advantages and limitations, and I lay out my suggestions for if you would possibly wish to use AWB – and when you need to most likely keep away from it.
Let’s dive proper in!
A fast overview of white steadiness
Earlier than I get too deep in my dialogue of Auto White Steadiness, I wish to make it possible for we’re all on the identical web page about white steadiness extra usually.
So what precisely is white steadiness and why is it so vital to digital pictures?
The rudimentary reply is that gentle (the inspiration of pictures) has variable color temperatures at totally different occasions of the day. Your eyes are significantly better at processing coloration than a digital digicam. Thus, a white object will all the time seem white to you – whereas a white object in various kinds of gentle will not all the time look white to your digicam, leading to unnatural coloration casts.
(These coloration casts usually exist alongside a blue-yellow spectrum in nature, although synthetic lights also can create inexperienced and purple casts.)
Now, white steadiness is the method that the digicam makes use of to take away these problematic coloration casts. Whenever you set your digicam to a white steadiness setting, you’re guaranteeing that it successfully counteracts unnatural temperatures and tints – in order that your photos extra carefully replicate what you see along with your eyes.
What’s Auto White Steadiness (AWB)?
Auto White Steadiness (AWB) is a digicam setting that tells your digicam to “guess” the perfect white steadiness possibility. In different phrases, if you set your digicam to AWB, it analyzes the scene and tries to choose a white steadiness that’ll make your images look pure.
(That is analogous to your digicam’s computerized publicity settings, the place your digicam tries to find out the perfect aperture, shutter velocity, and ISO values to create a tonally detailed picture.)
In my expertise, Auto White Steadiness can work, nevertheless it’s typically way more efficient if you’re outside coping with pure lighting, and it tends to wrestle if you’re coping with complicated lighting conditions.
How does AWB work?
To know when you need to use Auto White Steadiness, you could have a fundamental information of the totally different white steadiness presets your digicam provides. These can fluctuate relying on the digicam model, however they typically embody Daylight, Cloudy, Shade, Tungsten, and Fluorescent. Added to those are Flash, Kelvin, and Customized White Steadiness.
Observe: The Custom White Balance mode needs to be used when you have got particularly difficult lighting circumstances and have to nail the white steadiness completely. It permits you to level your digicam at a impartial portion of the picture, then creates a customized white steadiness impact that counteracts any coloration solid within the scene. It’s an underused possibility that provides nice outcomes, so examine your handbook and experiment with it someday.
Now, the Auto White Steadiness setting assesses your scene and chooses the brightest a part of your picture because the white level. Then it balances out the scene to make sure that this chosen white level seems utterly impartial.
Sadly, the white level your digicam chooses can fluctuate from one shot to the following, which may end up in picture sequences that includes very totally different coloration casts. Because of this, it’s a nasty concept to make use of Auto White Steadiness when capturing panoramas; in case your digicam modifications the white steadiness in the course of your panorama collection, the outcomes will look very unusual!
Auto White Steadiness comes with one other challenge: Your digicam can lock onto an space of the shot that’s not meant to be impartial (e.g., a yellow wall), after which attempt to steadiness it. When this occurs, as an alternative of neutralizing the colour casts, your digicam will create a few of its personal!
Right here’s the excellent news: Whereas Auto White Steadiness isn’t good, important enhancements have been made to AWB techniques, and the outcomes are getting higher. Nonetheless, it’s tough for Auto White Steadiness to deal with sure sorts of lighting (e.g., synthetic or mixture lighting setups).
It’s additionally value mentioning that you may typically run into a unique downside, the place AWB removes coloration casts you wished to maintain. This could occur if you’re capturing a sundown, or any scene the place the colour of the sunshine is crucial to the picture.
RAW Energy
Should you shoot in RAW, you’re most likely conscious that RAW information retain all the colour information captured by your digicam. This retention comes with an enormous profit: It permits you to change or select a unique white steadiness setting whereas post-processing your RAW information.
Because of this, many photographers argue that, so long as you shoot in RAW, you should use Auto White Steadiness with out challenge. (Although others argue that even when capturing in RAW, AWB does not give you the best colors.)
Even when we grant that RAW information will be successfully white balanced throughout post-processing, I nonetheless don’t suppose you need to use it on a regular basis.
Setting the white steadiness in-camera ensures that coloration rendition is constant throughout all of your pictures (e.g. when shooting a wedding), and it makes post-processing so much simpler, particularly when you’ve got a number of information to edit.
Additionally, AWB may give you totally different outcomes even when photographing the identical scene. Should you’re utilizing a zoom lens, you would possibly find yourself with one set of colours in your wide-angle shot – after which, if you zoom for a telephoto close-up, you find yourself with a unique set of colours. Positive, you’ll be able to right every thing when post-processing the information, nevertheless it’s typically simpler to only get the white steadiness proper from the beginning.
Take management of your digicam’s white steadiness settings!
You might wish to use Auto White Steadiness as a result of it’s simpler to let the digicam work out the precise settings based mostly on the scene in entrance of you. Nonetheless, as I defined above, this isn’t all the time the perfect method. Generally, it can save you your self a number of frustration in a while by nailing the white steadiness within the discipline. (And if you happen to’re ever capturing JPEGs, you positively wish to be sure to get the white steadiness proper; they don’t supply the identical flexibility as RAWs.)
Happily, setting white steadiness is just not as daunting because it sounds. And when the lighting circumstances are unchanging, you solely have to set your white steadiness as soon as (for these circumstances). Listed here are a number of fast suggestions:
If you’re outside on a sunny day, set your white steadiness to Daylight or Sunny. Whether it is cloudy, select the Cloudy white steadiness. Equally if you’re in shade, select Shade. These are very straightforward to recollect based mostly on their names!
When indoors, select Tungsten (or Incandescent) for incandescent lights. And when capturing an space with fluorescent lights, select Fluorescent.
That is merely setting your white steadiness to match your capturing circumstances.
You can even set your white steadiness to switch your current circumstances. When you begin experimenting with white steadiness and perceive the way it affects your images, you should use it to get inventive and make your pictures look hotter or cooler.
So long as you shoot in RAW, you’ll be able to all the time make changes in Lightroom, Seize One, or one other editor. However figuring out the right way to work along with your digicam’s varied white steadiness settings together with post-processing instruments will make you a simpler photographer!
Must you use Auto White Steadiness?
The quick reply is: Sure, typically.
The longer reply is that Auto White Steadiness is a useful setting when you find yourself uncertain of the white steadiness that may work for your scene. Should you shoot in RAW, you’ll be able to simply change your White Steadiness after the actual fact to search out the best choice. AWB will also be helpful if you’re photographing in quickly altering lighting circumstances, or if you happen to merely don’t thoughts fastidiously adjusting the white steadiness when post-processing your images.
Nonetheless, if you’d like extra management of your outcomes, select one of many digicam white steadiness presets, already tailor-made for particular circumstances, or use Customized White Steadiness to customise the setting on your particular scene. Setting your white steadiness within the discipline will remove that further post-processing step of fixing it from scene to scene and provide you with extra constant outcomes.
