Methods, skills and precautions of aerial photography

Aerial photography skills and precautions 1 aerial photography experience:

1. Charge the device before shooting:

Because most aerial photography equipment uses batteries, including airplanes, cameras, video transmission, monitors and so on. It needs to be charged, and the power lithium battery has large capacity and fast discharge, so it is basically impossible to charge outdoors, so all equipment should be charged before shooting.

2. Choose the right weather and time:

Photographers should have a deep understanding of the influence of light and weather on their works. Aerial photography doesn't have to be sunny. Cloudy weather is the best, so the light ratio will not be too big, the picture in the sky will be more beautiful and the composition will be more comfortable. It is best to choose morning light or afterglow for better shooting effect.

3. Pre-design aerial photography line:

Before shooting, we must first determine the theme, composition and basic route of the lens, reduce the invalid flight to a minimum, do a good job in analyzing the interference sources of the surrounding signals, and reduce the possibility of losing control.

4. Debugging the machine before taking off:

This is very important, because once God makes a mistake, it can't be made up, and the plane has uncontrollable risks. Machine debugging includes whether the basic parameters such as white balance, shutter and aperture of the camera are set reasonably, and whether the battery and memory card are installed. It is best to put one on the Shoot before the plane takes off and monitor it on the display.

5. Record in advance and buy insurance:

Over-the-horizon commercial aerial photography should be filed in advance according to local policies, and the corresponding commercial insurance should be purchased.

6. Avoid interference sources:

In aerial photography, it is a great challenge for pilots with less flight experience to avoid the interference of trees, high-voltage lines and communication base stations and pay attention to the attitude of the aircraft while monitoring aerial images. Many people may blow up the plane because they can't tell the attitude and course of the plane. It is necessary to judge flight altitude, speed, attitude and other information through OSD superposition data to ensure flight safety. In order to avoid electromagnetic interference and ensure safety, it is suggested that you learn attitude mode or manual mode to fly.

7, aerial camera lens group:

Just like shooting on the ground, aerial photography should be grouped. Using aerial photography aircraft, you can shoot the heights and angles that auxiliary equipment such as rocker arms can't reach, and shoot shots of different scenes and angles. In the process of aerial photography, it is strictly forbidden to be too high or too fast. Aerial photography is not a stunt, it is entirely for the plot. Guide the audience with lens language and blend in with the plot appropriately.

8. Try different shooting heights:

Aerial photography at the same flight speed and different altitudes gives viewers different feelings. The closer you are to the ground, the faster you feel, and the higher you are from the ground, the slower you feel. Therefore, the closer to the ground, the stronger the impact, the lower the flying height, the faster the speed and the smaller the crossing space.

9. Avoid greed:

Aerial photography is only an auxiliary tool. A shot that is enough to take off and land is not enough for one minute. Every second left blank increases the danger of one second. When shooting, simplify the complex, present it simply, and never play hard.

10, away from children and people:

Children and pets are full of infinite curiosity about the world. When they see the plane, they will go straight up. If the bomber is a big deal, it will cost tens of thousands of dollars. The consequences of wounding and crashing are unimaginable.

1 1, fly more and practice more, as the saying goes, practice makes perfect.

Aerial photography skills:

With the safety and controllability of aerial photography equipment greatly improved, only tens of millions of people need to buy an entry-level aerial photography plane, and they can take aerial photography with a little practice after returning. Aerial photography is widely used in film and television production, news reports and activity records with a new perspective and new way, but it is not easy to shoot an ideal shot. Aerial photography is both a technical activity and an artistic activity. Flying hands need to know camera settings, photographic composition and lens movement, and pan/tilt hands need to know. After fully understanding the equipment, you need to practice frequently, and the following shooting skills are generally used in aerial photography.

A, straight flight:

In GPS mode, flying in a straight line and hovering at a fixed point become very simple "skills". But there are many ways to shoot straight lines, such as:

1, fly straight ahead, lens forward:

This is one of the most commonly used techniques, and it is also often used to photograph coastlines, deserts, ridges and straight roads. In the picture, the lens moves forward, or you can slowly look up from the ground to the distance, and the lens is done in one go.

2. Fly straight ahead and look down at the camera:

Head-down shots are often used to photograph cities and forests, especially straight roads, neat rows of vehicles, trees and houses. Fly straight ahead, look down at the lens, and shoot different objects according to height and speed to reflect scale, quantity and uniformity.

3. Fly backwards in a straight line, and the lens retreats:

4, lateral flight, lens head-up:

Shooting the city in this way, especially after using the medium telephoto lens, has the feeling of urban forest, and in addition, it gradually moves away from the foreground and appears the background like shooting horizontally on the track.

5. Fly vertically up and down, with the lens looking up or pitching:

There is a feeling of taking an elevator, and there is an upward sense of strength vertically, which is suitable for shooting tall buildings in the backlight. The plane rose vertically with the camera overhead. This rapid pull-up action shot quickly expanded from local area to panorama. This trick can also be added with a circle movement, and the visual effect is very shocking.

Second, the diagonal flight:

The most commonly used skill in diagonal flight is "skimming", but it can be divided into the following situations:

1, flying obliquely downward, camera forward: the plane flew obliquely downward from a height to a building.

2. Fly obliquely upward, skim the foreground, the camera is forward, and the plane is upward: in short, it can also be called "pull up", which is often used in Hollywood and Indian movies, and it has a feeling of being suddenly enlightened.

3. Fly obliquely up to the target, turn around and shoot from the top of your head when passing by. The most classic is a scene in Mission Impossible 4.

4. Fly backward obliquely, skim the foreground, and the lens retreats, which is equivalent to reverse skimming, descending and retreating from the panoramic edge, and the subject appears in the foreground. Often used in the opening credits, the lens slowly shifts from the big environment to the individual. However, generally speaking, it is easier to pull up than to get down. If the descent speed is too fast, it is easy to cause bombers. Be more careful when there is wind. Generally, it is safer for multi-axis aircraft to descend below 2 meters per second.

Third, fixed-point hovering:

Today's flight control can easily achieve fixed-point hovering, and the entry-level flight control NAZA like DJI can basically stay still in the windless air. Fixed scenic spots are most suitable for taking pictures, and videos of some big scenes, such as the whole city and the great waterfalls, can also be taken in this way. The angle between the plane and the lens is fixed, which is suitable for shooting sports events in geometric buildings or stadiums.

Aerial photography of fixed-point circle of plane or camera: American movies are often used to shoot buildings, forests, roads, cliffs, waterfalls, temples, halls, stations and so on.

Fourth, follow the shooting:

Just like the follow-up of the camera stabilizer, the advantage of aerial photography is that it is not limited by space and can fly freely when the height and angle allow. It can be followed from the back, front and side, and is often used to shoot extreme sports such as racing, skiing and surfing. And some action movies are also used more. In addition, we often see live aerial photographs of police arresting people in American blockbusters, and they are all followed. There is a long shot of following the team at low altitude in Fast and Furious 5.

Five, flying around the fixed point:

Also known as the pen container, with a theme as the center, the plane circled around it to shoot. This move is most suitable for some isolated subjects. It is not difficult to shoot with multi-axis aircraft now, especially in GPS mode, it is not difficult to turn a perfect circle. However, there will be some difficulties when there is wind. The height of the plane will change in both downwind and headwind, and the downwind will rise and fall, which is difficult to control. In addition, we should also pay attention to the direction of the circle when shooting religious-related stupas, for example, general Buddhism should turn clockwise.

The common shooting techniques for fixed-point flying around are parallel altitude hovering and overhead hovering. When hovering in parallel, the height of the plane is the same as that of the subject, which can better highlight the subject, while the plane hovering overhead is higher than the subject. This trick can be used to show a person's loneliness, but at a slower speed.

Sixth, the route bypass:

The detour route often takes some very beautiful curves, and there is no clear shooting target, such as a rambling walk, which is more natural to shoot.

Precautions:

1, safety, absolute first, then NB control and lens, hit people and blow up machines, hahaha,,,

2. Resist "black flying", don't fly in air traffic control areas such as military administrative zones and airports, stay away from crowds, and work after obtaining permission to shoot. I witnessed the computer games confiscated by the police uncle and taken away and detained during the no-fly period, you know,

3. Learn more theories. The more proficient the theory, the more advanced the flight technology and the more savvy it is in flight.

Luck is always the enemy of security. Lack of common sense and momentary negligence are the biggest threats to flight safety. Flying must be foolproof. If you are not sure about 100%, don't practice. The psychology of trying is adventure, and the probability of failure is the highest!

5. In order to ensure safety, it is necessary to check the safety of aircraft equipment frequently. Communicate more, dissect more accidents.

6. When flying, keep yourself in the best condition and know your body, energy, emotions and feelings. As long as you are unwilling, lack of sleep, tired, depressed, in a bad mood and under too much pressure, you may make mistakes in operation and cause great disasters.

7. When flying at low altitude, be sure to pay more attention to external observation and pedestrians. This is fatal! ! !

8. The first flight after a long grounding must be slow, steady, thin and complete.

9. Don't trust your feelings too much, don't treat yourself as an experienced person, and don't be too confident.

10, fly more, practice more, and accumulate more experience. Over time, everything turns into steel.

1 1. In daily practice, you should take the initiative to understand the aircraft and learn to maintain it, so that problems can be solved on the spot.

13, the flight must not be neglected, and some emergency disposal methods are available at any time.

14, don't sit still and relax at any time during the flight, to prevent relaxation and paralysis after landing, and the propeller is not turned off after landing.

15, to ensure safety at all times, we must ensure the safety of every flight.

16. Treating a very serious flight with a reckless and contemptuous attitude is an important factor causing the accident.

17, it is important to fly happily, but it is more important to ensure safety. If you don't fly cold today, there will be tomorrow, but if you don't ensure flight safety, there will be no bright tomorrow.

18, don't fly after drinking, okay? ...

19, the battery must be unplugged in time after the electric plane flies.

20. If you feel that the plane is abnormal during the flight, land it immediately for inspection. Don't be too confident.

With the great improvement of the security and controllability of aerial photography equipment, aerial photography is widely used in film and television production, news reporting and activity recording with a brand-new perspective and a brand-new way. But it is not easy to shoot a shocking ideal shot. The following are some aerial photography experiences, skills and precautions summarized by aerial photography enthusiasts based on flight experience and network information:

1, photographers should have a deep understanding of the influence of light and weather on their works. However, aerial photography doesn't have to be sunny, and a little cloudy weather is the best. In this case, the light ratio will not be too large, the picture in the sky will be softer and the composition will be more comfortable. It's better to shoot at dawn or afterglow.

2. Before shooting, we must first determine the theme, composition and basic route of the lens, try to reduce invalid flight, do a good job in analyzing the surrounding signal interference sources, and reduce the possibility of losing control.

3. Machine debugging includes whether the basic parameters of the camera, such as white balance, shutter and aperture, are set reasonably, and whether the battery and memory card are installed. It is best to install one in the shooting before the plane takes off and monitor it on the display.

4. In aerial photography, avoiding the interference of trees, high-voltage lines and communication base stations and paying attention to the attitude of the aircraft while monitoring aerial images is a big challenge for "flying hands" with less flight experience. Many people may "blow up" the plane because they can't tell the attitude and course of the plane. It is necessary to judge flight altitude, speed, attitude and other information through OSD superposition data to ensure flight safety. In order to avoid electromagnetic interference and ensure safety, it is suggested that you learn attitude mode or manual mode to fly.

Like ground shooting, aerial photography should be grouped. Using aerial photography aircraft to shoot heights and angles that auxiliary equipment such as rocker arms can't reach, and shooting shots of different scenes and angles. In the process of aerial photography, it should not be too high or too fast. Aerial photography is not a dazzling skill, and it fully serves the shooting theme. Guide the audience with lens language and blend in with the theme appropriately.

6. In aerial photography at different altitudes, the same flight speed will bring different feelings to the audience. The closer you are to the ground, the faster you feel, and the higher you are, the slower you feel. Therefore, the closer to the ground, the stronger the impact, the lower the flying height, the faster the speed and the smaller the crossing space.

7. Aerial photography is only an auxiliary tool. A lens that can take off and land only flies for one minute, and every second left blank increases the danger of one second. When shooting, simplify the complex and present it in a simple way. Never play difficult moves.
