In the past, when we wanted to take aerial photography, the first solution was to use a manned helicopter + gyroscope. The biggest advantage of this scheme is: it can fly at high speed, up to 160 kilometers per hour; it can fly very high, and the altitude can reach 1000 meters. The disadvantage is: there is no way to fly very low for safety reasons, and it is difficult to get close to the subject.
Later, a scheme of using a model helicopter to mount the gimbal appeared. This scheme can bring the camera closer to the subject, but still does not solve the safety problem. The high-speed rotating propeller can reach a speed of more than 3000 per minute, which is still lethal.
The emergence of multi-rotor aerial photography drones is an excellent solution to the balance between safety and aerial photography. The price is lower, the maneuverability is strong, and the safety factor is greatly improved. So it also provides more ideas for the movie.
Aerial photography drones can fly very low, but the requirements for operators are very high. Aerial photography drones must still fly in the sky, but the distance from the ground when it works is much smaller than we expected.
Aerial photography drones can be very close to the subject. In the traditional concept, aerial photography drones fly high in the sky, and aerial photography drones can take shocking scenes. What is not known is that the extreme ground distance of aerial drones is very low. As long as the operator is technically reliable, it is not a problem to complete most of the follow-up shots.
In addition to the God's perspective of aerial drones, which brings a richer film language to film creation, aerial drones also have unique advantages over traditional shooting in difficult shooting scenarios such as space travel, high-speed movement, and tracking.
At the same time, from the perspective of technique, aerial photography can complete the shooting of pushing, pulling, panning, shifting and other shots. These shots usually need to borrow slides and rocker arms in the crew, and compared with commonly used equipment such as slide rail rocker arm, aerial photography has inherent advantages.
First of all, the operating cost of the rail rocker arm is too high. Generally, it takes 30 minutes to prepare the rail for a shot. Secondly, the operation requires a minimum of 3 people. In addition, the track is troublesome to maintain, has a short life span, and has extremely poor portability. If the road is uneven, using it on land or sand will also affect a certain degree of stability.
