Stop guessing which ND filter you need for your next shoot. Whether you are flying a DJI drone, capturing action on a GoPro, or using the Osmo Nano, this interactive calculator provides instant, pro-level settings for any environment. Simply select your device, your current conditions, and your target frame rate to get the exact ND filter, Native ISO, and Manual White Balance needed for a perfect exposure every time.

ISO 100Understanding ND Filters and Cinematic Settings
To achieve a professional “film look,” you must control how your camera perceives motion and light. This tool uses three core pillars of cinematography to generate its recommendations:
1. The 180-Degree Shutter Rule
In cinema, motion blur should look natural to the human eye. To achieve this, your Shutter Speed should always be double your Frame Rate (FPS).
- Example: If you shoot at 30 fps, your shutter speed must be locked at 1/60s.
- The Problem: On bright days, a 1/60s shutter speed will let in way too much light, turning your video into a white blur.
- The Solution: An ND (Neutral Density) Filter acts as sunglasses for your lens, cutting the light so you can maintain that slow shutter speed without overexposing.
2. Mastering Native ISO
Digital sensors have “Native ISO” points where they produce the cleanest image with the least digital noise.
- Daylight: This tool defaults to ISO 100 for maximum dynamic range and cleanest highlights.
- Low Light: For modern sensors like those in the Mini 3, 4, and 5 Pro or Osmo Nano, we recommend switching to the High-Gain Native ISO (usually ISO 800). This utilizes a secondary hardware circuit to produce cleaner shadows than simply “pushing” a lower ISO.
3. Locking Manual White Balance
Auto White Balance (AWB) is the enemy of professional video. If your camera is moving, the colors will “shift” as the lens points toward or away from the sun.
- Locking your Kelvin (K) ensures the color of the grass, sky, and skin tones remains identical from the start of your clip to the end.
- This tool suggests 5600K for standard daylight and 4800K for the “Golden Hour” to preserve those natural sunset oranges.
4. Digital Post-Processing (Sharpness & Noise)
Most consumer cameras apply aggressive digital sharpening that makes footage look “crunchy” and artificial. By setting your Sharpness and Noise Reduction to -1, you preserve the raw organic detail of the sensor, making it much easier to apply professional color grading in software like DaVinci Resolve.
