As a drone enthusiast, you’re likely no stranger to the importance of capturing stunning aerial footage. However, achieving that perfect shot can be a challenge, especially when it comes to managing light. That’s where Neutral Density (ND) filters come in – a crucial tool for drone pilots to control the amount of light entering their camera lens. But with so many options available, it can be overwhelming to choose the right ND filter for your drone. In this article, we’ll dive into the world of ND filters, exploring what they are, how they work, and most importantly, how to select the ideal one for your drone photography needs.
What is an ND Filter and How Does it Work?
An ND filter is a type of camera filter that reduces the amount of light entering the lens without affecting the color or quality of the image. It works by blocking a specific amount of light, measured in stops, allowing the camera to capture a wider range of tonal values. This is especially useful in bright conditions, where the camera’s sensor can become overwhelmed by excessive light.
Think of an ND filter like a pair of sunglasses for your drone’s camera. Just as sunglasses reduce the intensity of the sun’s glare, an ND filter reduces the amount of light entering the lens, making it possible to capture smooth, cinematic footage even in the brightest conditions.
Understanding Filter Stops and Density
ND filters are measured in stops, which represent the amount of light they block. A 1-stop ND filter, for example, reduces the light entering the lens by half, while a 2-stop ND filter reduces it by a quarter, and so on. The density of the filter refers to the amount of light it blocks, with higher densities blocking more light.
Here’s a breakdown of common ND filter stops and their corresponding densities:
- 1-stop ND filter: 0.3 density (reduces light by 50%)
- 2-stop ND filter: 0.6 density (reduces light by 75%)
- 3-stop ND filter: 0.9 density (reduces light by 87.5%)
- 4-stop ND filter: 1.2 density (reduces light by 93.75%)
Choosing the Right ND Filter for Your Drone
With so many ND filter options available, it’s essential to consider several factors when selecting the right one for your drone. Here are some key considerations to keep in mind:
Drone Camera Specifications
Before choosing an ND filter, make sure to check your drone’s camera specifications. Different cameras have varying sensitivities to light, so it’s crucial to select an ND filter that’s compatible with your camera’s capabilities.
- Some drone cameras, like the DJI Mavic 2 Pro, have a native ISO range of 100-12800, while others, like the DJI Inspire 2, have a range of 100-25600. A higher ISO range typically requires a stronger ND filter to achieve the desired effect.
Shooting Style and Conditions
The type of shots you’re trying to capture and the conditions you’re flying in will also influence your ND filter choice.
- If you’re shooting fast-paced, action-packed footage, you may want a stronger ND filter (e.g., 3-stop or 4-stop) to reduce motion blur and achieve a more cinematic look.
- For slower, more dramatic shots, a weaker ND filter (e.g., 1-stop or 2-stop) might be more suitable to capture a greater range of tonal values.
- If you’re flying in extremely bright conditions, such as near the equator or during midday, you may need a stronger ND filter to reduce the overwhelming amount of light.
Filter Quality and Material
Not all ND filters are created equal. Look for high-quality filters made from premium materials that won’t affect image quality.
- Glass filters are generally considered superior to resin or plastic filters, as they provide better optical clarity and are less prone to scratches or damage.

What is an ND filter and how does it work?
An ND filter, or neutral density filter, is a type of filter used in photography and videography to reduce the amount of light that enters the camera lens. By doing so, it allows for a wider aperture or slower shutter speed, which can help create a more cinematic look and feel. ND filters are especially useful when shooting in bright conditions, as they can help prevent overexposure and loss of detail in the image.
In the context of drone photography, ND filters are particularly important because drones often fly in bright, sunny conditions. Without an ND filter, the camera may be overwhelmed by the amount of light, resulting in washed-out or overexposed footage. By using an ND filter, drone pilots can capture more balanced and visually appealing footage, even in the most challenging lighting conditions.
What are the different types of ND filters available?
There are several types of ND filters available, each with its own unique characteristics and uses. Some common types of ND filters include variable ND filters, fixed ND filters, and hybrid ND filters. Variable ND filters allow for adjustable levels of light reduction, making them versatile and convenient to use. Fixed ND filters, on the other hand, have a fixed level of light reduction and are often used in specific situations.
In addition to these types of ND filters, there are also different coatings and materials used in their construction. For example, some ND filters may have a hydrophobic coating to repel water and oils, while others may be made with scratch-resistant materials. When choosing an ND filter for your drone, it’s important to consider the specific needs of your project and the conditions you’ll be flying in.
