To begin your journey in professional drone cinematography, you'll need a capable drone like the DJI Inspire 3 or DJI Mavic 3 Pro Cine for high-end work or the DJI Mini 3 Pro for portability. Essential accessories include ND filters for exposure control, extra batteries, and a robust carrying case. For better control and monitoring, use a tablet or a dedicated drone monitor like the DJI CrystalSky. Invest in fast, high-quality SD cards for smooth recording of high-resolution footage. For post-production, you'll need a powerful laptop capable of handling 4K video editing. Don't forget safety equipment such as propeller guards for indoor flights and a landing pad for rough terrain. As you progress, you may want to expand your kit with specialized equipment based on your specific cinematography needs.
