III. Shooting Techniques and Considerations
- Depth of Field and Aperture Selection: Choose the appropriate depth of field based on the desired shot, and select the corresponding aperture size.
- Light Control:
- Use a lens hood to protect the lens, block stray light, and achieve desired effects with color filters.
- Use ND filters to reduce light, achieving day-for-night effects or removing specific light sources.
- Use polarizing filters to reduce reflections and enhance color contrast in the image.
- Stability and Support:
- Due to the weight of the Arri Alexa Mini with accessories, use a saddlebag or DCUP for handheld shooting support.
- Ensure sufficient power by preparing multiple batteries for long shooting sessions.
IV. Post-Processing and File Management

- Adjust image processing parameters, aspect ratios, and resolutions within the software.
V. Maintenance and Care
- Lens Cleaning: Use lens cleaning tissue to clean the lens, avoiding non-disposable items like glasses cloths to prevent scratching.
- Interface Protection: Cables, especially EVF cables, are expensive. Handle with care to avoid damage.
- Cooling and Dust Prevention: Regularly clean fan dust to maintain good ventilation for the camera.
VI. Advanced Techniques
