What are the aerial photography skills?

Aerial photography can clearly show the geographical form, so it is not only a part of photography art, but also used in military affairs, traffic construction, water conservancy projects, ecological research, urban planning and so on. Next, I introduced the aerial photography skills for you, hoping to help you!

1, looking for prospects

Finding the right scenery as the foreground has several advantages: ① It sets off the shooting atmosphere; ② As the foreground changes, the lens looks more dynamic and rhythmic.

Step by step

Before aerial photography of this kind of lens, it is necessary to determine the focus in advance, followed by appropriate composition. Everything is ready, and flying hands is the main way to fly out of this picture.

Step 3 block the camera

"Contrast lens" can show the speed and momentum of the subject. As the name implies, hedging refers to the simultaneous acceleration and reverse flight of the aircraft and the moving subject. Crossing cars, bicycles, speedboats, etc. The biggest difficulty in this kind of shooting is how to judge the distance between the plane and the subject and the influence of airflow.

4. Feel the speed of the camera

Generally, the maximum speed of a multi-axis aircraft is 45km/h, and if it is chased by multi-axis shooting, the result will be very miserable. On the one hand, if the car accelerates, the plane can't catch up; On the other hand, if the car slows down, it is not realistic. We usually do it in two ways. One is flying close to the ground, that is, increasing the changing speed of the foreground and enhancing the sense of speed through the ground. Second, the use of a medium telephoto lens can enlarge the part, and at the same time the shooting prospect is faster.

5. Adjust the speed according to the scene.

Aerial photography of large scenes requires planes to fly at a faster speed. Because there are no foreground objects in the aerial photography of Dajingbie, and the distant buildings or mountains and rivers in the picture are far away from the plane, it is difficult to see the relative movement of the scenery in the picture when the plane flies slowly. The slow aerial photography of this lens looks more like a photo. Only when the plane flies fast can the audience see that it is a moving picture in a short aerial camera lens.

The aerial photography of xiaojingbie is the opposite of dajingbie. In small landscape aerial photography, the subject accounts for a large proportion in the picture, and too fast speed will make it difficult for the pan-tilt hand to keep the subject in the ideal position in the picture. Simply put, the plane is flying too fast, and it is difficult for the pan-tilt hand to keep up with the' object' to be photographed.

The common way is that the plane approaches the object at a faster speed; When approaching the subject, the plane slows down to ensure that the pan-tilt hand can keep up with the subject. Although the plane has a deceleration process in the whole process, because the deceleration time occurs near the plane and the photographed object, the proportion of the photographed object in the picture is large at this time, and the relative motion in the picture is more obvious. So in fact, the audience doesn't seem to notice that the plane has actually slowed down.

6. Backlit pictures

Backlight shooting can often achieve different sensory effects. In aerial photography, it is necessary to hide the plane in the shadow of the subject, so that the subject can shine in the sunlight background. But at this time, the choice of time is an important factor in the success of shooting, if you want to shoot a picture with both light and dark details. 30 minutes before and after sunrise and sunset is the best time.

7, improve the utilization rate of materials

In film or advertisement shooting, aerial photography and the shooting of the left picture are very important. In order to improve the utilization rate of aerial materials, in the Dajingbie aerial photography, the aerial picture should have a smooth pause time of 3 seconds, at which time both the plane and the pan/tilt remain motionless; In the process of shooting, the flight and movement of the plane in the direction of the platform need to be as smooth and uniform as possible; The picture on the left is the same as the starting picture, and GM needs a smooth pause of 3 seconds. Smooth and jitter-free materials are easier to use in film and television post-production.
