You might have experienced taking very bright pictures in low light whenever you are using flash. This problem can sometimes arise when the metrics of a frame are not balanced, and it doesn’t match well the aperture and ISO settings of your camera. For such conditions, features like Flash Exposure Compensations are there to help you capture some clear and colorful shots without capturing too dark or too bright images.

The function that allows you to apply exposure compensation to unleash the full power of your flash is known as flash exposure. You may use flash exposure to brighten darker regions of an image without impacting the overall exposure. Certainly, it’s a feature featured on all mirrorless cameras, DSLRs, and high-end compact cameras. Many of the top camera phones also offer this feature. To enable it, good cameras include an easy-to-find button; others need you to dig through a menu.
If you have been struggling with low-light photos and you don’t know how to take good photos with flash, then this guide is for you. We will show you what Flash exposure compensation is and how to use it for taking photographs.
Understanding Flash Exposure Compensation
From camera to camera, the variety of exposure correction capabilities provided varies. Many people limit the range to plus or minus two stops. The range of top cameras is closer to +/-5 stops. However, many completely automated shooting modes on DSLRs and mirrorless cameras do not enable manual overrides like exposure correction.
To access exposure compensation, users have access to one of the camera’s creative exposure modes, such as Aperture Priority (A or Av), Program (P), or Shutter Priority (S or Tv).
How to Use Flash Exposure Compensation
When you feel the need to use the flash exposure compensation feature, you need to understand a few things and make the perfect use of your options.
I’m Glad You’re Here! Photography is a fascinating art form that allows us to capture and preserve moments beyond imagination in time. However, for beginners and amateurs, getting started with photography can be intimidating, especially when it comes to choosing and using the equipment and techniques to follow.
Click below to read a comprehensive article for beginners to master the basics of capturing moments beyond imagination.
You can do so in one of two ways:
Quick Control screen:
- This is by far the easiest approach. To alter the amount of flash correction, highlight the Flash Exposure Compensation setting and twist the Main dial.
- Alternatively, if you like the old-fashioned approach, hit the icon or click Set to bring up the second screen in the picture, where you may alter the setting using the Quick Control dial, Main dial, or Multi-controller.
- The access is simple; sliding your finger along the scale or tapping the Brighter and Darker arrows will let you adjust the settings.
- When you’re finished, tap the return arrow or hit Set. The value of flash compensation displays on the Shooting Settings screen when it is active. In the viewfinder, the identical plus/minus flash sign appears but without the actual value.
Note: When you set the Flash Exposure Compensation to zero, the flash-power symbol vanishes from all displays until you return to Quick Control mode.
Second Shooting Menu:
- To see the left screen in the example below, go to the Shooting Menu and select Flash Control.
- To get the proper screen, go to Built-in Flash Settings. Now, as indicated on the right in the image, select Flash Exp. Comp. to bring up the same adjustment panel.
- Any flash-power adjustment you make, like exposure correction, remains in effect until you reset the control, even if you turn off the camera. So, before you use your flash, double-check the settings.
Pro Tip: The Auto Lighting Optimizer function may conflict with the effect generated by flash exposure adjustment; therefore, it’s best to turn it off.
Adjusting Flash Ratio
The Flash Exposure Compensation function, which influences the flash unit’s output level, may be used to modify the flash output. You can increase the flash power to +3.0 or decrease it to –3.0 by dialing in a positive flash exposure compensation while simultaneously dialing in negative exposure compensation.
Note: A setting of 0.0 indicates no flash adjustment, but you can increase the flash power to +3.0 or decrease it to –3.0 by moving the dial in order to go for a positive flash exposure compensation in negative exposure compensation.
Pro Tip: With a default flash ratio of 1:1, obtaining a 2:1 flash ratio requires an FEC of +1 and an EC of -1/2 to -2/3.
To reduce the flash ratio, input a negative flash exposure compensation while also dialing in positive exposure compensation (but not more than +1). Assuming a default 1:1 flash ratio, obtaining a 1:2 flash ratio necessitates an FEC of -1 and an EC of around +1/3 to +1/2. Finally, it’s worth noting that FEC isn’t always employed to alter the flash ratio. It may also be used to correct problems in the flash metering system of your camera.
The simplest approach to make your image brighter or darker is to use the +/- exposure compensation adjustment on your camera, which gives you complete control over the exposure of your shot. Exposure adjustment is available on almost every camera on the market today. It’s easy to use and can be used in a variety of circumstances, saving you time in post-production and helping you to obtain the photo you want with less effort.

Modes Of Flash Exposure
You will have to face the challenge of understanding the modes of exposure for flash photography. Some settings presume you simply want a fill flash, while others think your camera’s flash will be the primary source of lighting, ignoring ambient light. Fortunately, every camera uses its flash as either the primary or fill light source.
Knowing when and why your camera utilizes its flash in each of these situations is crucial.
- The behavior of the Aperture Priority (Av) and Shutter Priority (Tv) modes is significantly distinct.
- In Auto Mode, the flash only fires if the shutter speed falls below what is considered hand-held, which is normally around 1/60 of a second. As the light reaching the subject grows darker, the flash ratio gradually increases, but the shutter speed must be at 1/60 of a second.
- Program (P) mode also has the same features, except that it allows the photographer to require the employment of a flash in instances where the subject is well-lit, in which case the flash will operate as a fill flash. As the ambient light level rises, most cameras automatically reduce their fill flash.
- As a result, the fill flash ratio can range from 1:1 to 1:4. When the shutter speed is more than 1/60 of a sec, flash in Program mode behaves similarly to flash in Auto mode.
- The camera exposes ambient light in Manual (M) mode based on how you select the aperture, shutter speed, and ISO. The flash exposure is then estimated depending on the amount of light that is still required to illuminate the subject. As a result, manual mode allows for a significantly wider variety of flash ratios than the other modes.
Note: In Program mode, one must normally push their flash to “on,” causing the camera to use the flash as a fill flash. Unlike Auto and P settings, however, the flash ratio never exceeds roughly 1:1, and exposures are as long as necessary.
If a flash exposure is not feasible with that setting in any mode, the corresponding setting in your viewfinder will blink. This might include demanding an aperture outside of your lens’s range or a shutter speed quicker than your camera/flash combo can handle.
Factors Influencing FEC Selection
There are several things that can influence how your camera and flash meter TTL flash, and hence how much flash exposure correction has to be dialed in. This may include the reflectivity of your subject, how far the subject is from the backdrop, how much of the camera frame is filled by the subject, whether the subject is off-center or centered in the frame, available light, and the exposure algorithms used by the camera designers, and back-lighting.
As a result, when determining how much flash exposure correction to dial in, you must juggle all of this. A seemingly difficult endeavor that becomes simpler with practice.
Note: if your flash is simply used as a fill light, the actual flash exposure compensation can vary significantly without hurting the final image quality.
Editing Photos Captured with FEC
Although learning how to utilize flash exposure correction might be difficult, it doesn’t imply you can’t use images that aren’t precisely exposed. If you need to balance or change your flash exposure shots, editing them in Lightroom is a quick and straightforward way to do it. It may take some practice to become acclimated to shooting with flash, but keep in mind that your photographs may be quickly rectified and polished in post-production.
Here are a few easy methods to use Adobe Lightroom to modify and fix exposure:
- Select Auto to have Lightroom modify your image automatically.
- Experiment with the different levers that regulate highlights, blacks, shadows, and whites.
- Use the Exposure slider to adjust the overall brightness and darkness of your photograph.
Some Tips for Best Use of Flash Exposure Compensation
Using Daylight and Flash in the Same Shot
Using a flash outside on a sunny day is a terrific technique that is simple to use. For this, you will simply pop up your flash or place it in the camera’s hot shoe and shoot as you would for a daylight photograph. Flash metering and balancing of the two light sources will be handled by the camera.
However, changing the flash intensity to daylight brightness may drastically alter the appearance and feel of your photos.
Note: It’s feasible to get rid of unsightly shadows on your subject’s face generated by intense sunshine and brighten up subjects that are silhouetted by strong backlighting by employing flash as an additional fill-in light source.
To do this, you may need to lower the flash’s output power so that it does not take over and appear unnatural. Negative flash correction is used for this. If you want the flash to be the primary light source, set the flash exposure compensation to 0 and change the exposure compensation on the camera to -1 to darken the backdrop.
Against a dark and somber backdrop, this will make your subject stand out. When employing this method in low-light situations, it’s a good idea to use the camera’s Slow Sync setting. To preserve the compensating effect, the shutter speed might be reduced to less than 1/60 sec.

Pluses, Minuses, and Stops
A plus (+) setting brightens the image. A negative (-) value darkens the picture. Stops are exposure units that make up the exposure compensation scale. The quantity of exposure is doubled or halved with a full stop change. For more fine adjustments, most cameras provide intermediate ‘half stop’ or ‘third stop’ increments.
Depending on your subject and the metering method you’re using, it changes. A setting of +1 is generally normal for a snowy landscape (however, +0.4 or +3 may be required on occasion). With many views, you may take a photo, assess the outcome, and then reshoot with a different level of compensation to guarantee you obtain the desired effect. When calculating accurate adjustment amounts, the histogram may be quite useful.

FAQ’s
When is it appropriate to utilize exposure compensation?
When photographing something that is mostly black or white, you’ll almost certainly need to apply for exposure compensation. Shooting a white picture (such as snow-covered countryside) will cause the camera to underexpose the whole image.
What’s the variation between ISO and exposure correction, and how do you use them?
The contrast is that with ISO, you adjust for lack of exposure by magnifying the signal, but with EC, you raise the quantity of exposure your sensor receives, and it’s always better to obtain an ideal exposure when it comes to image quality.
Is there a link between exposure compensation and noise?
Exposure adjustment is similar to altering the ISO on your camera in terms of effect. Exposure correction is nearly always the preferable option because boosting the ISO also boosts the noise in your photographs!
