Small knowledge of aerial photography

1. What should I pay attention to in aerial photography?

Pay attention to the weather and site before aerial photography. The wind can't be too strong and can't exceed level 3.

Choose sunny weather, and the flight route should avoid the airport and the military flight route. Be sure to find an open place to keep the signal of G PS stable.

Have a general understanding of the surrounding terrain and harsh environment. You need to master some professional knowledge before controlling aerial photography of drones. UAV aerial photography is a miniature version of a real airplane. Although it is not as difficult as flying a real plane, it is much more difficult than flying.

The operator must be able to assemble and understand the circuit and have knowledge of aerodynamics. When the plane flies to you, the operation of the remote control is the opposite. You must concentrate on the operation. If you are not careful, the plane will crash or disappear.

The first rule of UAV aerial photography: safety Even if the fuselage is equipped with advanced safety equipment, accidents may occur. The most important thing is to increase your understanding of the machine, improve your own control technology, do more safety inspections in daily flights, and replace aging motors and batteries in time.

At the same time, try to avoid aerial photography at low altitude in crowded places. There are high-speed rotating blades on the plane, which may cause injuries if they fall out of control. Try to choose an empty place.

Avoid accidents. Photography, video cameras and related equipment. Photographic equipment is also one of the factors that determine whether a good photo can be discharged. A good high-speed camera may leave you with beautiful moments. Photographers can also be equipped with infrared cameras, which will get unexpected results when shooting rivers.

Shooting skills are also important. In addition to the above points, shooting skills are also an important factor in creating beautiful works. If you learn to use the following techniques, you may be able to shoot beautiful works that touch your heart. (1) Removing the UV mirror can reduce the interference in front of the camera, and the windows of civil aircraft have good anti-ultraviolet function.

(2) Give priority to ensuring the shutter speed. For clear aerial photos, it is usually necessary to ensure that the shutter speed reaches twice the focal length of the lens. When taking landscape photos, the aperture should be set at F8-F 1 1, and the shutter speed should be increased as much as possible. (3) Reduce one exposure. This camera is not designed for aerial photography. When shooting on the ground, the picture usually has a sky of 1/3; However, aerial photography is mostly downward shooting, and the picture rarely contains the sky. At this time, metering will be one step higher than correct exposure.

(4) The preset fine-tuning of white balance. Fetion of civil aviation science and technology is generally stored at an altitude of 7000- 1000 meters, and there are too many ultraviolet rays. Most of the photos taken are blue, so the white balance can be preset in advance. (5) Determine the focal length of the lens. When shooting at high altitude, it is difficult to keep the interlayer and lens of the window of civil aviation science and technology on the same picture, but choosing the lens with the focal length of 100-200mm can shoot relatively good quality works. Selection of UAV aerial photography at present, UAV aerial photography can be roughly divided into two types: model UAV and multi-rotor UAV. Because of its low cost, aerial photography is highly technical and difficult.

Compared with the aerial photography equipment assembled by planes, pan/tilt and cameras in the past, some aerial photography planes launched on the market now have integrated functions, just like the previous "fool camera", and the operation is actually very simple, which has become an aerial photography equipment that amateurs without professional background can play, such as the cheapest entry-level elf CCF40 aerial photography plane. For example, Rabida's Predator series RA-400 UAV aerial photography beginners suggest buying a cheap aerial car for flight training at first, because the first step of aerial photography is flying, which requires many different movements of training, and it is inevitable that various small situations will occur.

2. How do novices play aerial photography: Introduction to aerial photography skills of drones

1. Plan the route before shooting.

Let me have a general score. Avoid the environment with many people, buildings and large signal interference. Because the power of the drone is limited, you haven't tossed it yet, and there is no power.

2. Shoot low altitude first, then shoot high altitude.

Don't fly high as soon as you come up. The environment at high altitude is more complicated than that at low altitude. It is possible that we are calm at low altitude, but the wind is continuous at high altitude. It is difficult to operate at high altitude, so novices should play at low altitude first.

3. A route is repeated.

If you want to take a wonderful aerial photo, you must do it again and again. Practice makes perfect, and you will catch more wonderful things.

4, first play the entry-level machine, and then play the high-end machine.

The risk of bombing is too great. If you don't suffer heavy losses, you will learn from scratch honestly. Take an entry-level drone to practice, and it is not expensive to fall. For example, Harberson H 107C, damn it, it gives me the willies, but it never breaks.

3. What are the precautions for novices to operate drone aerial photography?

For beginners, first of all, we should do simulation exercises on the computer, such as hovering, flying around, flying in figure 8 and so on. Remember not to directly control the real machine. After these skills are proficient, they will fly in an empty unmanned field with a low-power training machine, then fly without load with an aerial camera, and finally hang up the tripod head for test flight.

Finally, the reader is reminded by a jingle in the model airplane field: "There is no trivial matter in model airplane flight, and skilled control is the key. Novices are good at asking questions, practicing, and staying away from the crowd without showing off.

Don't treat the equipment as a toy, you will regret neglecting safety. "The following are matters needing attention.

1, safety, absolute first, then NB control and camera, hit people and blow up planes, hahaha. 2.* * * "Black Flying", you can't fly in air traffic control areas such as military administrative zones and airports, stay away from crowds, and do your homework after obtaining shooting permission.

I witnessed computer games being confiscated and taken away by police uncles 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, you know ... 19, you must unplug the battery in time after the electric plane flies.

20. If you feel that the plane is abnormal during the flight, land and check it immediately. Don't be too confident. (eagle drone).

4. What should I pay attention to in aerial photography?

With the development of China's economy, more and more photographers like to create works on airplanes. Aerial photography is becoming more and more fashionable and professional. The photographer will open the hatch and lean out to take pictures. But amateur photographers may not be able to rent a special plane and have their own aerial photography time. However, we can create on civil airliners through tourism or indulge in aerial photography. Maybe we can really take good photos.

Professional photographers and amateur photographers will be interested in aerial photography, so what problems should be paid attention to in aerial photography? 1, Weather conditions Aerial photography requires high weather conditions, so it is necessary to choose sunny weather conditions with soft light and transparent sky for shooting. 2, physical quality For professional photographers, having a good body is more conducive to aerial photography. Only when you have good physical fitness and step on a hot air balloon, airship or small plane can you have enough physical strength to pick up a heavy camera and complete the shooting process in the absence of oxygen at high altitude. 3. Flight safety cannot deny the possibility of potential plane crashes or fatal accidents in aviation activities.

This may be one of the focus issues that policymakers and comrades are most concerned about. There are two statistical conclusions that we should understand: first, compared with ground transportation and ground transportation, airplanes are the safest and have the lowest accident rate.

Of course, once an accident happens, it will cause huge social impact and huge losses. .

5. What are the precautions that a novice drone aerial photographer needs to know?

After all, playing drone aerial photography is the perfect combination of drone aerial photography technology and photography technology. Now UAV aerial photography has been widely used in photovoltaic inspection, transportation, film and television, wedding and many other industries.

The seemingly relaxed flying drone still needs certain skills and skills. The biggest problem for the novice drone aerial photography is that aerial photography is not planned. What is a complete aerial photography process for drones? Now let's talk about the process and skills of anti-UAV aerial photography in Kong Lan.

The aerial photography process of drones is basically similar to the shooting process, such as shooting movies and TV series. Before shooting, you need a script and shoot according to it. So is aerial photography. You should write a script before shooting.

The content of the script includes (positioning, theme, form of expression, each shot: shooting people or scenery, shooting place and time). After all this work is done, you can shoot.

To sum up the shooting errors of new pilots in aerial photography of unmanned aerial vehicles: (1) No on-site investigation was conducted before takeoff. For example: obstacles in the venue, pedestrians coming and going.

From this point of view, it is very likely that the drone crashed, causing property damage. (2) There is little or no transition frequency when the novice shoots.

According to the normal shooting process, it should be one shot at a time. Because there is no transition or the frequency of transition is small: the flying hand or photographer has limited viewing angle, and the shooting time is prolonged because the shooting result is not in place; The position of the flying hand is relatively fixed, and it will fly directly to the next lens position (the distance between them is close) for shooting, which is very likely to encounter obstacles or signal occlusion, causing the drone to crash.

(3) Novices don't have strict shooting requirements. When shooting, after the novice takes off, there is no rule and he doesn't follow the script.

For example, when we are watching a movie or shooting a TV series, a director will say "stop", which means stop. The director will consider whether to shoot again according to the shooting effect.

Aerial photography should also be like this, one at a time, and if it fails, it will be retaken. (4) The shooting schedule for novices is inappropriate.

The shooting time has a lot to do with the whole video. The timing is not in place, and each shooting environment sets the tone of the whole video.

Shooting the same scene at noon and at night, there is a clear difference between shooting in summer and shooting in winter. So the script says to shoot at this time (put it down before you finish shooting).

If you don't follow this method, post-production will be very troublesome, and the works produced will not be so real.
