If you've ever wondered if drone filters are even useful, the answer is clear - they are, and a big one. Filters are one of the easiest ways to significantly improve the quality of drone footage - whether it's video or photography. While it may seem like a small addition, the right filter can completely change the resulting image. In this article, we'll look at what filters exist, how to use them correctly, and why they should be a must-have in every pilot's kit.
Filters are optical accessories that are attached to the lens of a drone or camera. Their main task is to regulate the amount of light that reaches the sensor, or to remove unwanted glare and reflections. The right filter will provide you with better contrast, more accurate colors, and overall more professional-looking footage. You will see the biggest difference when shooting video - filters help preserve natural motion blur, creating a professional cinematic look.
To get the most out of your filters, shoot in manual mode (M). When set to automatic, your drone's camera often increases the Shutterspeed or ISO, which can cause unsightly motion blur or noise in your image. It's a good idea to set at least two values directly:
A simple rule of thumb is → Shutter = 2 × FPS (frames per second). This creates natural motion blur that doesn't make your video look cheap or "jerky".
➡️ 30fps → 1/60 sec.
➡️ 50 fps → 1/100 sec.
➡️ 60fps → 1/120 sec.
The lower the ISO → the clearer the image. The recommended ISO for daytime shooting is 100-400.
The most well-known ND filters are designed to reduce the amount of light that hits the camera sensor, allowing you to shoot in bright sunlight with ideal shutter settings, which is important for a cinematic look (so-called motion blur ).
In practice:
Darkening levels:
ND filters are labeled with numbers (e.g. ND4, ND8, ND16, ND32, ND64 …). The higher the number, the stronger the darkening:
CPL filters eliminate glare and increase color saturation. They are used in photography of water, glass, wet surfaces and landscapes. There are also combination ND/PL filters that offer the benefits of both solutions at once and are a great choice for most pilots.
In practice:
UV filters were originally used to filter out ultraviolet light, but with modern sensors their use has shifted more to protecting the lens or gimbal lens from dust, scratches, and impacts.
In practice:
There are two most famous variants: Black Mist and CineMist (or Gold Mist, White Mist). Their role is to soften the image, give it a cinematic look, and reduce the harshness of the light.
What are they used for:
Differences:
In practice:
• House shots for a real estate presentation? → ND/PL filter removes glare from windows. Recommended drone - DJI Mini 4 Pro /DJI Mini 5 Pro
• Bright midday sun over Bratislava? → ND16 or ND32 for correct exposure. Recommended drone - DJI Mini 5 Pro
• Hiking by the lake? → CPL filter will enhance colors and remove reflections from the water. Recommended drone - DJI Mini 3 / DJI Air 3S
• Sunset by the Danube? → Soft ND with natural brightness and a warm touch of scenery. Recommended drone - DJI Mavic 4 Pro
The most versatile solution is an ND/PL filter – it combines both image darkening and polarization. One set of ND/PL filters (e.g. ND8/16/32) will cover most situations – from cloudy skies to harsh midday sun.
No, original filters for DJI drones (e.g. Freewell, PGYTECH, PolarPro) are designed to be lightweight and balanced. As long as you use a filter designed for a specific model (e.g. DJI Mini 4 Pro), the gimbal will maintain full stability and range of motion.
You can fly without filters, but the results tend to be lower quality – especially in bright light. Without a filter, the camera will often overexpose the sky while leaving shadow areas dark. Drone filters improve exposure balance and are essential if you want to achieve a cinematic look for your video or professional photos.
