- Filter Strengths: ND filters come in various strengths, such as ND4, ND8, ND16, ND32, ND64, ND1000 and ND2000, each reducing light by a specific fraction.
- ND8 (3 stops): Use this filter during slightly cloudy conditions or during sunrise/sunset when the sunlight is moderate.
- ND16 (4 stops): Suitable for bright days with lots of sunlight.
- ND32 (5 stops): Ideal for very sunny days or bright environments.
- ND64 (6 stops): For extremely bright conditions, like at the beach or snowy environments with intense sun.
- ND1000/ND2000: These strong filters allow for long exposure photography in the middle of the day.
Camera Settings for Drone Long Exposure
Mastering camera settings is crucial for achieving stunning long exposure shots with your drone.
Key Settings to Adjust
- Manual Mode: Essential for controlling shutter speed, aperture, and ISO.
- Shutter Speed: Determines the length of time the camera’s sensor is exposed to light. Slow shutter speeds (e.g., 1-8 seconds) create motion blur.
- Aperture: Controls the amount of light entering the lens and affects the depth of field. The Mavic 3 is the only current DJI model with a variable aperture.
- ISO: Measures the camera’s sensitivity to light. Keep it as low as possible (ISO 100) to minimize noise.
- White Balance: Adjust for accurate color representation.
- File Format: Shoot in RAW format to preserve maximum image detail and color information for post-processing.
- Focus: Set manual focus to infinity; autofocus may struggle in low light.
Optimizing Settings for Different Conditions
- Bright Sunlight: Use a high-strength ND filter (ND64 or higher), low ISO (100), and a small aperture (if adjustable) to prevent overexposure.
- Overcast Days: Use a weaker ND filter (ND8 or ND16), low ISO (100), and adjust the aperture and shutter speed to achieve the desired exposure.
- Low Light: Increase ISO (while minimizing noise), use a wider aperture (if adjustable), and experiment with longer shutter speeds.
Composition Techniques for Aerial Long Exposure
While technical settings are important, composition plays a vital role in creating compelling aerial long exposure photographs.
Composition Tips
- Rule of Thirds: Divide your frame into a 3×3 grid and position key elements along the lines or at their intersections.
- Leading Lines: Use natural or man-made lines to guide the viewer’s eye through the image and create depth.
- Symmetry and Patterns: Capture striking symmetrical compositions and mesmerizing patterns from a bird’s-eye view.
- Framing: Use foreground elements to frame your subject and add context to the scene.
- Color Contrast: Utilize color contrast to create dramatic compositions.
- Striking Shapes: Look for interesting shapes that reveal themselves from an aerial perspective.
Considerations for Aerial Composition
- Lighting: Pay attention to lighting conditions and shoot during the golden hour (just after sunrise or before sunset) for warm colors and soft illumination.
- Height and Angle: Experiment with different heights and angles to find the most compelling perspective.
- Balance: Strive for balance in your composition, ensuring that the elements in your frame complement each other.
