When photographing landscapes with a bright sky and darker foreground, itโs not always easy to capture the full dynamic range in a single frame. Thatโs where Graduated Neutral Density (GND) filters and multiple exposures come into play; two common techniques that help balance light in challenging scenes.
At first glance, using a GND filter may seem like the faster, simpler solution. And in many cases, it is. But when the horizon is uneven, like with jagged mountains or tall trees, a GND can actually do more harm than good. On the other hand, blending multiple exposures gives you full control in post-processing, but it takes more time and effort.
So, which approach is best?
In this article, weโll take a closer look at both techniques, compare their strengths and weaknesses, and explore when to use each one in the field. Youโll also find example images and tips to help you decide which method best suits your style and workflow.
What is a Graduated Neutral Density Filter?
A Graduated Neutral Density (GND) filter is a partially darkened filter designed to balance the exposure of an image, most often by darkening a bright sky while leaving the landscape untouched.
These filters come in various strengths (like 1-stop, 2-stop, or 3-stop) and with different transition types:
- Soft edge: gentle, gradual transition, great for uneven horizons
- Hard edge: abrupt transition, ideal for flat horizons like seascapes
- Medium edge: a balance between the two, often the most versatile
- Reverse grad: darker in the center and fades upward, useful for sunrise and sunset
You slide the filter into a holder (typically on a square or rectangular system) and position the transition to match your horizon. When used in the right conditions, a GND filter allows you to capture a well-balanced image in a single exposure, eliminating the need for exposure blending or additional post-processing.

What is “Multiple Exposure for Better Dynamic Range”?
Multiple exposure bracketing is a technique where you capture a series of images at different exposure levels, usually one normal exposure, one underexposed (to protect highlights), and one overexposed (to bring out shadow detail).
This approach allows you to capture the entire dynamic range of a scene, especially in situations where one part of the image is very bright and another is very dark.
Once youโve captured the bracketed images, theyโre blended together in post-processing using tools like:
- Lightroom’s HDR Merge (fast but less control)
- Photoshop exposure blending
- Luminosity Masks in Photoshop (for maximum control over which tones appear where)
This method gives you much more flexibility than a single exposure and avoids the problem of darkening elements that rise above the horizon, something GND filters often struggle with.

Graduated ND Filters or Multiple Exposures: Which Should You Use?
So, which method is best?
The truth is, thereโs no one-size-fits-all answer. Both Graduated Neutral Density filters and exposure bracketing have their strengths, and the better choice depends entirely on the scene, subject, and style of photography youโre working with.
If the horizon is flat and uncluttered, a GND filter can help you capture a perfectly exposed image in-camera, with no need for blending later. But in scenes with mountains, trees, or other objects rising into the sky, using a GND can create unwanted darkening, and thatโs when multiple exposures shine.
Letโs look at when each technique works best, starting with GND filters.
When to Use Graduated Neutral Density Filters
Graduated ND filters are a great solution for balancing the exposure between a bright sky and a darker foreground, especially when the transition is simple and clean.
I personally use GNDs frequently, not just for the look they create, but also because they enable me to work faster in the field and reduce post-processing time. Theyโre especially useful when the light is changing quickly, such as at sunrise or sunset.
Here are a few examples of when a GND filter works well:
- When you want to minimize editing and capture a strong image straight out of the camera
- Scenes with a flat or gently sloped horizon, such as oceans, beaches, open fields, or distant hills
- When youโre shooting directly toward the sunset and want to darken only the upper portion of the frame
Example of When to Use Graduated ND Filters
Take a look at the image below; the mountains project slightly above the horizon, but itโs still manageable. In this case, a Medium or Soft Edge GND is the right tool. A Hard Edge filter would darken the mountains and top part of the chimney unnaturally, but with the right transition, the effect remains subtle and natural.
The image below shows another situation where you can use a Graduated ND filter; in this case, a hard-edge would work just as well as any other. Because no elements project above the horizon, we don’t have to worry about unnaturally darkening any unwanted subjects.
GND filters arenโt perfect, but when used in the right conditions, they offer an elegant, fast solution to a common exposure challenge.
Are Graduated ND Filters Still Worth it?
Many photographers today ask, โAre GND filters still worth it?โ The short answer is yes. When used in the right conditions, they can dramatically reduce editing time and help you capture a balanced exposure straight out of the camera. Even in the age of bracketing and powerful editing tools, GND filters remain a fast, reliable solution in the field.
If you’re looking for the best GND filter for landscape photography, I strongly recommend the NiSi Medium Graduated ND Filter (read my review here). Itโs the most versatile option for real-world use and works well with a variety of scenes; from flat seascapes to rolling hills.
When to Use Multiple Exposures to Capture the Dynamic Range
Multiple exposures are the better choice when the scene contains complex elements that extend above the horizon, such as mountains, trees, cliffs, or buildings. In these situations, a Graduated ND Filter will also darken those elements, which can lead to unnatural contrast, loss of detail, or even blocked shadows.
Notice how the cliffs rise unevenly across the horizon in the image above. If a GND filter were used here, the sky would be darkened, but so would the upper portions of the mountains, resulting in a muddy, unrealistic look.
In the image below, tree branches frame the mountain and extend well into the bright sky. A GND would darken these branches to the point where theyโd lose all detail and appear almost black, while branches below the horizon would remain properly exposed. The result would be imbalanced and visually jarring.
This is where exposure bracketing shines. By capturing multiple frames at different exposures, you can preserve detail in both the highlights and shadows, and blend them together later in post-processing to achieve a natural balance.
While the blending process can be time-consuming, especially in complex scenes, the results are often worth it. For scenes like the second example, I highly recommend using Luminosity Masks in Photoshop, which allow you to control exactly which tonal ranges are blended and where.

Limitations of Exposure Bracketing
While multiple exposures give you more control in post-processing, theyโre not always practical in the field. If youโre photographing scenes with wind-blown grass, moving water, or fast-changing clouds, it can be difficult to blend exposures cleanly, even with advanced techniques like Luminosity Masks.
In these cases, a GND filter often gives you a cleaner result, faster.
Pros and Cons: Graduated ND Filters vs Multiple Exposures
Now that weโve explored when each method works best, letโs take a look at the key differences side by side. This comparison will help you quickly understand which technique is more suitable for different types of scenes and workflows.
Graduated ND Filters | Multiple Exposures | |
Ease of Use | Simple to use in the field | Requires post-processing |
Speed | Fast setup, minimal editing required | Fast setup but requires time in an editing software |
Best For | Flat or gently sloped horizons | Complex scenes with uneven elements (mountains, trees, etc.) |
Image Quality | One single raw file, less noise | Combines shadow/highlight detail, but more room for artifacts if not done carefully |
Control | Less flexible, the filter affects the entire upper frame | Full control over every part of the image |
Weather Flexibility | Can be tricky in the rain and requires attention to raindrops | May be tricky in windy conditions or when elements move |
Equipment Needed | Filter holder and filters | Just a camera with manual mode (and ideally a tripod) |
Learning Curve | Easy to learn, quick results | Steeper learning curve (especially for manual blending) |
While both techniques have their strengths, neither is objectively better than the other; they simply suit different situations. Many photographers choose to carry both tools so they can adapt to the scene in front of them. In some cases, you might even find yourself combining them: using a soft GND filter in the field and still blending exposures later for maximum control.
Summary
Both Graduated ND filters and multiple exposures are valuable tools for dealing with high-contrast scenes in landscape photography. Rather than asking which one is “better,” itโs more useful to understand when each method makes sense.
Use a Graduated ND filter when the horizon is relatively flat and clean, as it allows you to balance the exposure in-camera and save time in post-processing. But when the scene includes mountains, trees, or other complex elements rising above the horizon, multiple exposures offer more control and a more natural result.
In the end, itโs not about choosing one method over the other. Itโs about building your toolkit and learning how to adapt your approach to the scene in front of you.
FAQ: Graduated ND Filters vs Multiple Exposures
Yes. In some cases, using a GND filter to slightly reduce the contrast and then bracketing exposures can give you even more flexibility in post-processing. This approach works especially well in extreme lighting conditions like sunrise or sunset.
Not necessarily, but many photographers still prefer using GND filters in the field to minimize the number of bracketed images required, making post-processing easier. Filters also allow you to see a more balanced exposure through the viewfinder or on your LCD, which can help with composition and lighting decisions on the spot.
If youโre new to filters, the best GND filter for landscape photography is a Medium Edge model. It offers a good balance between control and flexibility, especially in scenes with slightly uneven horizons. I personally recommend the NiSi Medium Graduated ND Filter.
Thereโs a learning curve, especially if youโre using Luminosity Masks for more precise manual blending. But once you understand the basics, youโll have much more control over your images. For simpler blends, Lightroomโs HDR Merge is a fast and automated option.
Yes, GND filters are usually rectangular or square and need a filter holder to position the transition line accurately. Systems like those from NiSi or Kase are lightweight and easy to set up. Avoid circular GND filters, as they can’t be shifted up and down based on your composition.
