Modern digital cameras have a variety of metering modes that they use to evaluate the light coming through the lens and help you choose your exposure settings. Each one is different and designed to fit a specific need. As you gain experience with them you will start to know which metering mode to use for any given scene you are shooting.
If you’re shooting portraits you might want to use Spot or Center-weighted metering, while landscape shooters may prefer the versatility of matrix or evaluative mode. Knowing which mode to use often comes with time and practice. But what if I told you there was a metering mode built-in to some cameras that could basically guarantee your shots would come out properly exposed every single time? Well, if you believe that then I’ve got a bridge in New York I’d like to sell you.
Highlight-Weighted Metering Mode
However, if your camera has Highlight-Weighted metering it will certainly help you get better results from your photos. While I can’t guarantee your pics will be perfect every single time, it can really come in handy if you’re not sure how to meter your scene and want a solution that you know you can rely on.
Different metering modes for different situations
The reason photographers use specific metering modes when shooting various scenes is that they want to make sure the right thing is properly exposed. For example, if you’re shooting a portrait it’s important to make sure your subject’s face is neither too bright nor too dark, even is it means some background elements will end up bright white or pitch black.
Center-weighted metering can solve this problem by helping you arrive at an exposure setting such that whatever is in the middle of the frame (i.e. your subject’s face) is exposed just right. Other metering modes such as Spot, Matrix/Evaluative, and Partial Metering all perform similar functions in that they help you make sure you have just the right camera settings to get precisely the important part of your composition properly exposed.
Highlight-weighted metering tosses all that out the window. In the process, it could also dramatically alter your approach not only to metering a scene but to photography as a whole.
I used Center-weighted metering here to make sure this couple was exposed just right, even though the background is a bit too bright. I cared more about the couple looking good than the tree leaves behind them.
Enter Highlight-Weighted Metering for Select Nikon Cameras
Available on only a few Nikon cameras, (D5, D850, D810, D750, D500, and D7500 as of the time of this writing) Highlight-weighted metering utilizes the incredible dynamic range of modern image sensors to give you a massive degree of control over your photos. Provided you don’t mind doing a bit of legwork in Lightroom, Photoshop, Luminar, or other post-processing software.
It works by looking at the brightest elements of a scene (instead of specific areas like the center or the focus point) and using those as the basis for taking an exposure reading. On the surface, this might seem like a terrible idea because doing so would obviously mean a great deal of your photo could, as a result, be much too dark and underexposed to be usable.
Accessing Highlight-Weighted Metering
I’ve talked to some photographers who own cameras that can do Highlight-Weighted metering, and some of them aren’t even aware that their cameras have this capability. It’s not that surprising since Nikon doesn’t seem to go out of its way to advertise the feature, and even if you know about it you still may not know how to enable it.
To access this feature, press the metering button on your camera and then turn the control dial until you see an icon that looks the same as spot metering, with the exception of an asterisk in the top-right corner.
You will see the same icon if you look at the rear LCD screen of your camera, and as soon as it appears you’re good to go. However, figuring out how to enable Highlight-Weighted metering is one thing but understanding how it works, when to use it, and how to get the most out of it is another matter entirely.
Exposing for the Highlights
Before I get too deep into what this all means, it’s important to understand that Highlight-Weighted metering isn’t really the best solution to use for everyday shooting. It’s designed to make sure the brightest portions of your composition are not overexposed, which means a great deal of the photo is going to be shrouded in darkness.
You also won’t really see the advantages of using it unless you shoot RAW because it’s designed to give you an image that is extremely flexible due to the amount of data you have to work with during the post-production phase. Since JPEG files toss out such a huge amount of image data, they’re not much use with Highlight-Weighted metering because you simply don’t have much room to edit your photos when developing them in Lightroom.
Metering Mode Comparison
As an illustration of how Highlight-Weighted metering works, consider this series of three images. I took the following shot using Matrix metering mode, which tries to get a good overall balance between highlights and shadows. It’s a mode that many people use by default since it helps you get properly-exposed images in most shooting situations.
Matrix metering resulted in a good overall exposure but the sky is so bright that it can’t be fixed in post-production.
You can see that the camera tried its best to balance out the highlights and shadows, and the resulting image is decent but there is a massive portion of the sky that is simply too bright and can’t be recovered in Lightroom, Photoshop, or any other post-processing software.
Using Highlight-Weighted metering meant that my camera helped me adjust the exposure settings such that the brightest parts (i.e. the sky) were not overexposed, which resulted in an image that seems unusable at first.
Highlight-weighted metering preserved the brightest portions of the image but left the rest vastly underexposed. This is the image as it came right out of the camera.
Fortunately, due to the incredible dynamic range in modern camera sensors, an image like this is perfectly usable. The key is that the highlights haven’t been lost or clipped, so the sky is exposed just fine while the dark portions of the image still contain so much data (because I shot in RAW) that it can still be transformed into a print-worthy photo with just a few clicks.
The sky was exposed properly, with plenty of shadow details still available for editing. This is the same image as above, after processing to pull detail out of the shadow areas.
Some Caveats
As you might expect, there are some caveats to using this approach as well as a few questions.
First of all, experienced photographers might wonder what the big deal is with this approach since similar results can be had by simply using exposure compensation. That is if you take a shot and see that the image is overexposed, just compensate by underexposing it a few stops. The problem with this approach is that it’s a multi-step solution which means a critical moment can sometimes pass you by while you are adjusting the exposure. However, using Highlight-Weighted metering ensures that the brightest parts of your image will never be clipped and therefore have plenty of data to use when editing.
It’s also worth pointing out that in order to get the benefits of Highlight-Weighted metering you need to be willing to edit your photos afterward in order to bring up the shadows and adjust your images accordingly. If you’re used to shooting JPG or doing minimal editing, it might not be worth the additional time that this solution adds to your workflow.
Finally, to get the most benefits you need to use low ISO values since the data from the sensor will be more usable. Sensor dynamic range drops off at higher ISO values so if you find yourself shooting at ISO 6400, 3200, or even 1600 you won’t be able to bring up the shadows nearly as well as you could with images shot at ISO 100 or 200.
Another example
For one more example, here’s a series of photos of a goose that illustrate this concept in action. This first image was taken using standard Matrix metering which did its job pretty well. Overall the scene is properly exposed, except for one glaring exception: the overexposed part right at the base of the bird’s neck.

After seeing my results I quickly switched to the Highlight-weighted metering mode. In doing so, my camera made sure that the brightest part of the image was properly exposed, which left the rest extraordinarily dark.

Fortunately, there was plenty of color data to extract from the shadows, so a little finessing in Lightroom resulted in an image that I’d be happy to post to my Instagram feed.

What if you don’t have a Highlight-weighted metering mode?
If you don’t have Highlight-weighted metering built into your camera you can approximate its effects by using Spot metering and the exposure lock button on your camera. This would allow you to set exposure values based on what you deem to be the brightest part of the composition, lock in your settings, and then recompose your shot before snapping the shutter. It’s not as simple or elegant as having the camera automatically meter the scene based on the brightest part of the composition, but it’s worth trying if your camera doesn’t have this function.
Conclusion
I like to think of Highlight-weighted metering as another useful arrow to have in my photography quiver, but not something I use all the time for every one of my shots. For most images, I tend to default to Matrix metering since it will usually give me a properly-exposed shot that I can tweak if I need to.
However, when I find myself in situations with extreme contrast between the lightest and darkest portions I will often switch over to Highlight-weighted metering so I can stop worrying about checking my settings and dialing in exposure compensation. That way I know that I’ll end up with images that I can edit however I need to in Lightroom because nothing will be overexposed.
