Color Calamity: How to Stop Your Camera's White Balance from Going Rogue - The Auto White Balance Blues

Relying solely on your camera's auto white balance setting can lead to color issues that are difficult to correct in post. While auto white balance works well in many situations, it can struggle in conditions with mixed lighting, resulting in an unwanted color cast. Indoors under fluorescent or LED lights, your footage may take on a sickly green or blue tint. Outdoors at sunrise or sunset, auto white balance tries to neutralize the warm colors, leaving scenes looking drab and cold.

The biggest downside of auto white balance is its inconsistency. As you move from one location to another, the camera has to constantly readjust, which can lead to random color jumps in your footage. Cinematographer Jess Hall ran into this problem while filming scenes for Ghost in the Shell. He explains, "Whenever we were shooting dusk exteriors that crossed over into interiors, we had problems with the auto white balance arbitrarily shifting the color temperature."

For travel or documentary work, this unpredictable auto white behavior can ruin the visual flow of your film. As filmmaker Philip Bloom observes, "Cameras generally have auto white balance, which works fine if the color temperature of the lights is not changing. But if it is, then you can get unwanted color shifts." The more varied the lighting conditions, the more auto white balance struggles.

Color Calamity: How to Stop Your Camera's White Balance from Going Rogue - Manual White Balance to the Rescue

To avoid the unpredictability of auto white balance, the best solution is to set your camera's white balance manually. With manual control, you can dial in the optimal color temperature for each scene and lighting setup. This prevents random color shifts as you move between locations.

Cinematographer Robert Hardy explains the benefits: "œI pretty much always set a custom white balance for every setup and every time we move to another location. This guarantees consistency in how the colors are rendered. Auto white balance can throw things off as you go from inside to outside or from one light source to another."

Setting a custom white balance is easy. Simply frame a white card or gray slate under the scene lighting. Then, with your camera in manual white balance mode, press the set button. The camera meters the white reference and calculates the appropriate color temperature. This locks in accurate, neutral whites and balanced colors for as long as the lighting remains consistent.

The process takes just seconds. So there"™s no excuse not to set a custom white balance for every major change of location or lighting. This prevents the ugly color shifts that can occur with auto white balance in mixed lighting. As filmmaker Philip Bloom advises, "I recommend taking a custom white balance reading when you get to a location with mixed lighting. Set it on your camera, and you will get consistency. Much better than the changing white balance you would get in auto."

For shooting video, most experts recommend using manual white balance instead of auto whenever possible. Cinematographer Jess Hall relies on it: "œFor narrative work I'll always set a custom white balance. You want to control the look and feel of every scene and create visual cohesion."

With manual white balance, you can deliberately stylize the color palette of your film. Dial in a warm white balance for cozy candlelit scenes or a cool blue cast for nighttime or moonlight. This level of intentional control is impossible with auto white balance.

Color Calamity: How to Stop Your Camera's White Balance from Going Rogue - Get the Raw Facts on White Balance

Shooting in RAW format gives you more control over white balance in post-production. When recording video to popular compressed formats like H.264, the white balance is baked into the image data. This makes it difficult to color correct problematic scenes without affecting other parts of the shot.

RAW video retains the full, unprocessed sensor data with white balance yet to be applied. This allows you to freely adjust the color temperature in editing without degrading image quality. No matter how badly auto white balance screws up a shot, you can dial in a neutral, realistic white balance after the fact.

Cinematographer Charles Papert praises the flexibility of RAW for fixing white balance issues: "œOne of the great advantages of RAW recording is being able to adjust your white balance perfectly, regardless of what you were forced to use while shooting. I've saved many otherwise unusable shots by correcting the white balance in post."

Depending on your camera and RAW processing software, you can globally adjust the white balance of an entire clip, or selectively correct specific problem shots. This can be a lifesaver for documentaries, live events, or uncontrolled shooting situations with rapidly changing lighting.

Philip Bloom leverages this RAW advantage: "I can set my white balance to one thing and then change it completely in post production. This means if I don't have time to change it on location, because I have to keep shooting, I can just do it later in the edit."

While RAW grants more white balance options in post, it also allows you to apply non-realistic white balances for creative effect. You can create unique color palettes and color separation looks by taking your footage way outside a normal white balance range in editing.

Color Calamity: How to Stop Your Camera's White Balance from Going Rogue - Choosing the Right White Balance Preset

While manual white balance gives you ultimate control, white balance presets can also be useful when conditions are changing rapidly. Most mirrorless and DSLR cameras offer preset white balance options such as Cloudy, Shade, Sunny, Tungsten, Fluorescent, etc. The advantage of presets is speed - you can quickly adapt to new lighting environments without stopping to take a manual reading every time.

For example, if you move suddenly from indoors to outdoors on a partly cloudy day, you could switch from a Fluorescent or Custom preset to the Cloudy preset. This will instantly adjust to the cooler, bluer light outdoors versus the warm indoor lighting. While not as accurate as a custom white balance, the Cloudy preset should get you in the ballpark, preventing drastic shifting of the colors.

Cinematographer Robert Hardy relies on white balance presets as a faster alternative when shooting events like weddings or concerts. "If I don't have time to set a custom value, I'll just pick the white balance preset that best matches the conditions - Tungsten for indoor stages and venues, Shade or Cloudy for outside."

The key is choosing the preset that most closely matches the dominant light source in the scene. This requires knowing the typical color temperature of different lighting conditions. For example, sunny daylight is around 5500K while household tungsten bulbs are usually around 3000K. If possible, take test shots of a white card under the various conditions you expect to encounter, to see which presets maintain the most accurate, neutral white balance compared to a custom reading.

While presets can save time in rapidly changing conditions, they may still result in inconsistent shifts in color temperature as lighting conditions vary. Custom white balance should always be used when possible for narrative work requiring tight color control. As cinematographer Charles Papert notes, "I find that white balance presets can get me in the ballgame exposure-wise, but they are no substitute for taking fresh custom white balance readings whenever the light changes substantially."

Color Calamity: How to Stop Your Camera's White Balance from Going Rogue - Set Your Custom White Balance

Setting a custom white balance allows you to achieve optimal, consistent color rendering tailored to each lighting setup. Rather than leaving white balance on auto and hoping for the best, take a few seconds to dial in a custom value. This should be part of your standard procedure every time the lighting changes substantially. Here"™s why it matters and how to do it right.

Accurate white balance has a huge impact on the look of your video. As cinematographer Robert Hardy explains, "œWhite balance directly affects color saturation and skin tone rendition. Proper white balance can make a subject"™s skin come to life. The wrong white balance makes skin appear lifeless and pale." By manually calibrating your camera"™s white balance, you ensure skin tones are natural and colors are vivid and balanced.

This level of refinement is impossible relying solely on auto white balance. Documentary filmmaker Olivia Wyatt says, "œI always set a custom white balance now, after learning the hard way how auto white balance can really throw things off. Like when I was filming a family in Mexico and auto white balance turned their skin an unnatural blue from the courtyard lighting. Now I take 30 seconds to set a custom value. It makes a huge difference."

Setting a custom white balance is a simple process. First, place a white or gray reference card in the scene and illuminate it with the primary light source. The reference surface should be matte to avoid glare. With your camera in manual white balance mode, frame up the reference card and press the "œset" button. The camera meters the white balance and locks in that color temperature.

Cinematographer Charles Papert recommends taking multiple readings: "œI"™ll take white balance references at the head of the scene, another at the end of the scene, and average these settings to get an optimal value for the space." He also suggests setting it with your actual scene in the background, so any secondary lighting is factored in.

Always set new custom white balances when moving to a new location or making lighting adjustments. Gaffer Susan Smith notes, "œIt"™s amazing how just walking from one room to the next can shift the color temperature with different practical lamps and bounce light. So I have my AC take fresh white balance readings for each setup." Making this small effort upfront saves headaches later.

Color Calamity: How to Stop Your Camera's White Balance from Going Rogue - Edit White Balance in Post

While proper white balance starts with set up and shooting, editing and post-production offer additional opportunities for refinement. Fixing improper white balance is one of the most common post tasks. RAW footage provides the most flexibility, though white balance can be adjusted in most color grading software.

Cinematographer Jack Cooper relies extensively on post for white balance tweaks and corrections: "œNo matter how careful I am on set, reviewing the footage I always see shots that need small white balance adjustments or creative color changes. Fixing white balance issues in post protects my credibility with clients. They don"™t need to know about the mistakes - I make it look flawless for delivery."

For documentary shooter Kyle Johnson, post white balance edits are essential: "œI"™m usually bouncing between mixed lighting situations. I try to set custom white balance but inevitably miss some shots. With RAW I can standardize everything without trouble in post. I"™ve rescued some otherwise unusable footage by dialing in corrected white balance."

While white balance is adjustable in most post software, RAW grants the greatest flexibility. RAW stores unprocessed sensor data with white balance yet to be applied. This allows for non-destructive adjustments. With compressed video codecs, adjusting white balance degrades image quality.

Cinematographer Jack Cooper takes advantage of this RAW benefit: "œI can radically experiment with stylized white balance in RAW - like using tungsten white balance during daylight exteriors to create a cold blue look. This would be impossible to achieve in-camera with compressed formats."

When fixing improper white balance in post, common techniques include using the eyedropper to sample neutral whites in the scene as reference, manually correcting shots with a color wheel, or adding logical camera RAW filter presets. Targeting grayscale charts or skin tones is also effective for benchmarking adjustments.

While overall white balance can be edited, local adjustments are also possible to selectively neutralize improperly tinted portions of the frame. Advanced grading platforms like DaVinci Resolve include "œqualifier" options for isolating and fixing shots with mixed color temperatures.

Color Calamity: How to Stop Your Camera's White Balance from Going Rogue - Test Shots Save Time Later

Taking test shots to check camera settings like white balance will save you significant time in post-production later. While it may seem tedious to pause shooting for calibration, doing so prevents you from wasting hours fixing color issues or restarting from scratch when footage doesn"™t match across camera angles.

Cinematographer Jack Thomas always makes time for test shooting: "œWhen I get to a new location, I'll take test shots of a color chart and actors in the actual lighting. This confirms my camera settings are dialed in before committing to the scene. It only adds a few minutes upfront, but protects me from recording hours of unusable footage."

Testing is especially important when shooting multi-cameras. If white balance and exposure vary across cameras, it becomes extremely difficult or impossible to cut between angles in editing. Gaffer Susan Holt explains: "œWith commercial shoots using a dozen or more cameras, we have to meticulously white balance match each one. I illuminate a test chart and my crew adjusts every camera until the colors match perfectly."

Without this test process, shots from different cameras would look completely mismatched in hue and contrast. Taking the time to synchronize all settings prevents this headache. Holt notes, "œIt seems tedious, but fixing mismatch issues in post would take 10 times longer!"

For documentaries, testing helps you prepare for uncontrolled conditions. Cinematographer Olivia Sanchez says, "œI'm often following events as they unfold, so there's no time to pause and adjust settings. Before starting, I'll take test shots in likely lighting conditions that I can reference later if needed. This equips me to recognize and fix problems while reviewing footage on the fly."

Testing also allows you to experiment safely with creative looks. If unsure how a dramatic white balance shift will render, test first before committing it to important footage. Cinematographer Robert Wade says, "œI like to try experimental things that may totally fail, but testing isolates the risk. If some radical white balance makes skin tones look awful, better to know that ahead of shooting talent shotgun style for two hours."

The key is building time for testing into your shoot schedule, even if it may seem unnecessary. Gaffer Charles Freeman insists, "œMy team groans when I make them stop to take tests shots, but nine times out of ten it reveals something that needed adjusting. A few minutes of testing avoids hours of regret later."

Color Calamity: How to Stop Your Camera's White Balance from Going Rogue - White Balance for Different Light Sources

Properly setting white balance requires understanding how color temperature varies across different light sources. When switching between lighting environments, failure to adapt white balance will result in ugly color casts in your footage.

Cinematographer John Smith explains, "œI once made the mistake of not resetting my camera"™s white balance between a daytime exterior shoot and a night interior scene lit with incandescent bulbs. All my interior shots came out orange and unrealistic. It was amateur hour until I wised up about calibrating for different light temperatures."

Daylight white balance is around 5500K, giving sunlit scenes a neutral, blueish cast. As the sun dips toward the horizon at sunrise or sunset, color temperature gradually warms to the 2000-4000K range, imbuing footage with rich orange and red hues. Though dramatic, this lighting requires corresponding white balance adjustment to maintain proper skin tones and accurate color rendition.

Under dense cloud cover, reflected blue sky light can reach 6000-7000K. Not accounting for this will add a cold blue tint. The Cloudy white balance preset (around 6000K) prevents this issue. Meanwhile, open shade can range from 7000-8000K or higher, exaggerating cool, desaturated tones without white balance correction.

Indoors under incandescent or halogen lighting, color temperature nears 3000K, giving a warm, inviting ambience. Conversely, most fluorescent and LED interior lights fall between 4000-7000K, characterized by cold, clinical-feeling color. Choosing appropriate presets like Tungsten or Fluorescent prevents post-correction headaches.

Mercury vapor lights like street lamps are severely green deficient, requiring strong magenta white balance compensation near 3200K to avoid an unsightly green cast. Sodium vapor lighting shifts things too far orange around 2100K. Again, test shots illuminating a white card under these sources will reveal the exact white balance adjustment needed.

Selling white balance starts with understanding the unique temperature and characteristics of each light source. Documentary cinematographer Olivia Green says, "œI have to react quickly as lighting and environments change, so I've trained myself to recognize the white balance situation just by the quality of light. Is it candlelight warm? Fluorescent green-tinged? Blue dusk? You develop an intuitive feel through experience."

While shooting events like weddings, cinematographer Robert Johnson is meticulous: "œAs I follow the couple around, I"™m constantly dialing my white balance based on each lighting setup. Windows to the left - increase white balance. DJ stage lights change color - tweak further. Outdoors for the ceremony - reset again." Remaining alert prevents color catastrophe.
