    Because you're not standing high enough and the plane isn't stationary, it's harder to capture. Here are some tips for snapping, I hope it will be useful to you.

    Technique 1: Grab the right angle to make her legs longer in seconds, and when taking a full-body photo, tell her that the top of her head should be blank and her feet should be at the edge of the camera, so that the composition can become longer legs in seconds.

    Technique 2: Use the steps to lengthen the leg proportions, you can use the height of the steps to let one leg toe down forward, which can lengthen the whole leg proportions.

    Tip 3: Unexpected people and scenery are combined, you can use some scenery to take a large angle of view of the overhead shot of people and scenes, which will be more interesting than tourist photos.

    Skill 4: Make good use of the light at dusk, you can make good use of the light at dusk to shoot some beautiful **, the light at dusk will always give people a soft feeling, so it is very important to make good use of the light at dusk.

    Tip 5: When taking photos for your friends, you can look for natural frame compositions in the scenery, such as rearview mirrors, windows, doors, stairs full of geometric elements, etc.

    Because the plane is so far from the ground, even if you look at the sky from a tall building, it will only rise a few hundred meters, just like if you look at the moon from the ground and barely move, in fact, the moon will rotate at a speed of kilometers and seconds.

    It's too far away.

    The plane is about 10,000 meters or so above the sky.

    1. Hang a camera outside the plane, and what you see is an incomplete fuselage.

    2. On the roof of a high-rise building, shoot with a super telephoto lens. The plane is far away, and the elevation angle is not felt.

    3. It is indeed another plane tracking and shooting. Zoom in with a telephoto lens.

    The reason why airplanes can fly is because of the role of the wings.

    The cross-section of the wing is made of a concave and convex structure.

    Some knowledge of fluid mechanics and aerodynamics is required.

    For example, Bernoulli's equation simply says that the slower the flow velocity, the greater the air pressure.

    There is also the flow notation, that is, the flow rate = flow through a very cross-sectional area * flow velocity. The air flow per unit time is constant.

    The convex air at high speed reduces the cross-sectional area of the local flow, the flow velocity increases, and the air pressure decreases.

    The concave makes the high-speed air flow increase in the local cross-sectional area, and even produce a short period of retention in the concave, the flow rate slows down, and the air pressure increases.

    When the air pressure difference between the upper and lower wings is sufficient to overcome the aircraft's own weight, it can naturally fly in the air.

    Of course, when taking off, you also need to tilt the wings and hold them up by the air.

    To put it simply, an airplane takes off and flies through the air by the upward lift generated by its wings. From the cross-section, the leading edge of the upper surface of the wing is uplifted, while the lower surface is flat, so that when the engine produces a forward reasoning to push the aircraft forward, when the air flows through the upper and lower surfaces of the wing, because the air below flows faster than above, a pressure difference is generated, and when the plane moves fast enough, this pressure difference is greater than the weight of the aircraft, and the plane is sent into the sky.

    First know why airplanes can fly in the sky;

    The reason why airplanes are able to fly in the sky is the result of the interaction of four forces.

    The four forces are:

    1) The thrust of the engine.

    2) The resistance of the air.

    3) The aircraft's own gravity.

    4) The lift of the air.

    The aircraft takes off by the thrust of the engine to generate speed, and the speed generates lift through the shape change of the wings, the thrust is greater than the drag, and the lift is greater than the gravity, so that the aircraft can take off and climb high. When the aircraft climbs to the cruising altitude, the small throttle is closed, which is called level flight, at this time, the lift is equal to gravity, and the thrust is equal to the drag, that is, the constant speed flight.

    Does the plane have to take off against the wind?

    Of course not"Definitely"Hoo! The plane can take off against the wind and downwind!

    According to the theory of flight, the advantages of aircraft taking off against the wind are:

    1.Increase the indicated airspeed of the aircraft, so that the aircraft reaches the normal take-off speed in advance (which is equivalent to delaying the stall timing of the aircraft and increasing the steering performance of the aircraft).

    2.Shorten the runway length required for take-off and allow the aircraft to fly off the ground earlier (which is equivalent to reducing the wear and tear of tires and parts).

    3.In the unlikely event that the aircraft abandons take-off on the runway for any reason, the headwind helps the aircraft to slow down and stop and there is also a longer remaining runway available.

    Rely on the wing to generate lift. As long as the lift of the wing is generated by the pressure difference between the upper and lower sides of the wing. This pressure difference obeys Bernoulli's law, which depends not only on the shape of the wing (which can be changed, and the aircraft is mainly determined by changing the shape of the aircraft during flight), but also on the speed of the aircraft relative to the air in which it is located.

    So, the plane is not good with the wind, but with the headwind, if you have a friend who flies, please wish him a good wind! This speed is mainly generated by the engine. But it can't be said to be certain.

    The minimum take-off speed of an airliner is 240 km hIf there is a strong air flow when the engine is turned off in the sky, it will not fall for a short time. The length of time depends on the speed of the air current, the speed of the aircraft, and the attitude of the aircraft at this time.

    However, because the airplane itself creates resistance to the air, no matter how strong the air flow is, if you turn off the engine, it will eventually fall off!

    The key to whether an airplane can fly or not is the ratio of the upward buoyancy of the air to the downward gravity of the aircraft. If the buoyancy is greater than the gravitational force of the aircraft, the aircraft can fly, but if it is the opposite, it cannot fly. The wing design of the aircraft is key.

    The upper plane of the wings is slightly arc-shaped, and the viscous resistance of the air flying over its surface is small, the airflow is fast, and the pressure of squeezing the plane downward is small. The lower plane of the wings is straight, and the viscous resistance is high when the air flows at high speed, and the pressure on the lower plane of the wings is stronger than the upper surface, so that the aircraft obtains upward lifting force, which is similar to the increase of buoyancy. As the plane moves faster and faster, the pressure difference between the upper and lower wings increases, and eventually the force of the upward lift exceeds the gravitational force of the aircraft, allowing the aircraft to take off.

    This is the physics knowledge of junior high school.

    Where the air flow is fast, the pressure is smaller than where the air flow is slow.

    The wings of the airplane are convex above and flat below. In this way, the distance on the same time is large, that is, the speed is large, so the pressure is small.

    So that the airflow is lifted from under the wings of the plane!

    Of course, this is explained from a relatively simple point of view!

    When modern civil airliners are designed, there are corresponding intake valves in the engine compressor, and a certain amount of air compressed by the engine compressor is introduced into the cabin through the pipeline, so that the air circulation in the engine room is renewed. Of course, during this introduction process, the air will be pressured and filtered. Atmospheric properties such as air density decrease with altitude.

    As a result, the aircraft flies at high altitudes and passengers do not feel a lack of oxygen.

    The vast majority of the lift of the aircraft is generated by the wings, the tail usually produces negative lift, and the lift generated by other parts of the aircraft is very small and generally not considered. The airflow reaches the leading edge of the wing and divides into two streams, the upper and lower airflows, which flow along the upper and lower surfaces of the wing, respectively, and rejoin at the trailing edge of the wing and flow backwards. The upper surface of the wing is relatively convex and the flow tube is thinner, indicating that the flow rate is increased and the pressure is reduced.

    On the lower surface of the wing, the air flow is blocked, the flow tube becomes thicker, the flow velocity slows down, and the pressure increases. As a result, there is a pressure difference between the upper and lower surfaces of the wing, and the sum of the pressure difference perpendicular to the direction of the relative airflow is the lift of the wing. With the help of the lift gained from the wings, the heavier-than-air aircraft overcomes its own gravity due to the Earth's gravity and soars into the blue sky.

    Fixed-wing aircraft takes off by the pressure difference between the upper and lower wings, when the aircraft accelerates on the run, due to the different shapes of the upper and lower wings, resulting in different air densities up and down, according to the Bo effort equation, the density is proportional to the speed, when accelerating to a certain speed, the pressure difference in the atmosphere can lift the aircraft Rotary-wing aircraft, that is, takes off by the reaction force generated when the rotor rotates, and when the rotor rotates, the reaction force generated on the wing is decomposed into an upward force, and a force in the direction of rotation of the wing, which is counteracted by the rotation of the tail rotor, and when the former reaches a certain point, *** flies.
