A complete collection of aerial photography in autumn

In winter aerial photography, the temperature drop can't be prevented! Affected by the cold weather and environment, if you rush into battle without adequate preparation, you will inevitably encounter unexpected embarrassment and even accidents.

Aircraft batteries are all lithium batteries. When working in a low temperature environment, the internal resistance of the batteries will increase, resulting in a decrease in discharge capacity, which may lead to insufficient maximum thrust of the aircraft and make it difficult to maintain stable flight.

Suggestions for using batteries in winter:

1. Before flying, the battery must be fully charged to ensure that the battery is in a high voltage state;

2. Preheating: Fully preheat the battery to above 20℃ (you can check the battery temperature through the app);

3. Keep the plane hovering for about 1 min after take-off, so that the battery can fully preheat itself by using internal heat;

4. Operate the swing gently to avoid flying in a violent posture;

5. When the weather is cold, the flight time may be shortened, so it is suggested to pay attention to the battery power of the aircraft in real time during the flight;

6. It is recommended to return early to avoid low-power return.

Low temperature not only affects the flight performance of aircraft, but also affects the mobile equipment and handling stability. Therefore, heat preservation measures must be taken during the flight.

Mobile equipment insulation:

Most mobile devices use a built-in lithium battery, which is similar to the principle of aircraft batteries. In the low temperature environment, the power consumption of mobile devices increases obviously, the battery activity decreases, and abnormal phenomena are prone to occur during use. Pay attention to the warmth of the mobile device when flying, and pay attention to the phenomenon that the mobile device may automatically shut down and the app flashes back.

Keep your hands warm:

In winter flight, if your hands are exposed to cold air for a long time for flight control, your fingers may be stiff due to low temperature, resulting in slow control response. Therefore, hands should be kept warm before flying to avoid long-term flight and prevent hand frostbite.

Snow is an important subject in winter aerial photography, but if you want to take a picture of the beautiful world wrapped in silver, you should pay more attention to the adjustment of exposure and tone.

Increase exposure:?

Regarding underexposure, there is a proper term in photography called "white plus black minus", that is to say, on a white background, the light metering system of the camera thinks that there is more light than the actual situation, and the photos taken will be underexposed. Therefore, when shooting the snow scene, we need to increase the exposure appropriately to make the exposure of the snow scene normal and appropriate.

Adjust the white balance:

The automatic white balance of the camera is easy to get the correct tone in sunny days, but it is often not the most accurate effect in snowy days. If automatic white balance is used, the snow scene will be gray and look opaque. Therefore, it is necessary to adjust the white balance of the camera according to the environment at that time, so that the color of ice and snow in the photo is closer to the white seen by the naked eye.
