We often see in movies and TV series that the sky is still clear at the beginning, and suddenly there is lightning and thunder, pouring rain, how is this filmed?
Lightning thunder
First, shoot in real thunderstorm weather.
In order to save costs and make the scene more realistic, some crews will choose to shoot in real thunderstorm weather.
To know which day it rains, they often read the weather forecast in advance.
Rain
However, they will also prepare artificial rainfall equipment such as sprinklers.
Because you don't know when the rain will stop, and you don't know how much rain will fall.
The thunder and lightning is filmed when the thunder is hit, and then edited.
Of course, there are also lightning bolts and thunder that are computer-synthesized and clipped to rainy days.
Second, artificial rainfall is carried out with fire hydrants.
Generally large crews will invite to the fire truck to spray water, the water source used is also the water tank of the fire truck, directly to the high altitude spray can be, of course, this cost is still relatively expensive, in addition to the relationship to find the fire brigade, the difficulty coefficient is higher.

As for the thunderbolt, it can be a real picture taken or a computer composite screen cut over.
Third, the black tape for rural bathing is placed on a high place, the lotus head is opened, and artificial rain is carried out.
Is to find a larger rural bathing black plastic bag, the amount of water in this plastic bag is still enough to use, and then place the plastic bag at a high place, be sure to be higher, open the lotus head, you can.
This artificial rainfall is ideal for low-cost TV series and movies.
Lightning can also be a real picture taken on the spot or a computer-generated picture spliced away.
Fourth, sprinkle water with high-pressure sprinkler trucks and carry out artificial rainfall.

If the crew is not willing to wait for the rain, does not want to trouble the fire brigade, and disdains the use of rural bathing tape, then the choice is to use a high-pressure sprinkler.
However, the high-pressure sprinkler can only sprinkle water for four minutes, so when renting a high-pressure sprinkler, you must rent at least two sprinklers, one for sprinkling rain and one for filling the water source.
Fifth, spray water with a high-pressure spray gun to carry out artificial rainfall.

If the crew is not willing to wait for the rain and does not want to trouble the people of the fire brigade, they do not care about using the tape used for rural bathing, and feel that it is too expensive to rent a sprinkler truck, they can use a high-pressure spray gun to spray water and artificial rain.
If you are shooting thunderstorms through artificial rainfall, then you must not shoot on a sunny day.
If it rains on the ground and the sky shines brightly, then the filling is revealed.
Therefore, the crews who chose to shoot thunderstorms with artificial rain chose to shoot at dawn or sunset.
Of course, it is impossible to meet a cloudy day.
If you're shooting at dawn, get all your gear ready before 4 a.m.
In order to shoot more realistically in thunderstorms, the crew also had to dim and blow raindrops with a hair dryer.
It is relatively easy to photograph rain, because as long as there is a water source, artificial rain can be implemented, but it is very difficult to shoot snow.
So, how did the crew shoot the snow?
First, go to a real snowy place to shoot.
Snow is not the same as rain, and it is impossible to rain all the time, but some places can snow continuously.
For example, the 91st version of "Snow Mountain Flying Fox" is filmed in Changbai Mountain, which has been snowing all year round.

Second, use a snow machine to make snow.
Snow machines
Snowmaking technology is now available, and snow in many ski resorts is made by snow machines.
Some crews want to shoot pictures of winter, don't have to wait anymore, and use snow machines to make snow.
The snowflakes in the fantasy drama "Magic City" are made with a snow machine.

Third, use a snowflake machine to "make" snow.

The difference between the snowflake machine and the snow machine is that the snow produced by the snowflake machine may not be real snow, but salt, fertilizer or foam particles (PVC foam plastic) and so on.
The snowflake machine uses the strong air flow generated by ultra-high pressure to turn the snowflake oil into snowflakes flying in the sky, and the effect is quite realistic.
Although the audience still looks beautiful, the actors are not so good to shoot.
However, the cost of this technology is much lower, and some small-cost movies or TV series can be adopted.
Fourth, use a computer to synthesize snowflakes.
One advantage of snow over rain is that on a snowy day, just seeing snowflakes can prove that it is snowing, and on rainy days, if you are not wet, you cannot prove that it is raining.
Therefore, you can use computer special effects to synthesize snowflakes in the sky, so that the audience feels that it is really snowing.
Many viewers now particularly like this special effect.
However, producers will not rely on special effects, after all, as the saying goes: do not work hard in the early stage, and tire out the intestines in the later stage.
Dear friends, do you think it is easier to photograph thunderstorms (rain) or snow?
