"You see this, Hatton and I came up with it, we put the IMAX camera on top of the jet remote control plane, and controlled the plane from the Oriental Pearl all the way to the Dongpu New Area. Looking at this set of scenery, the sun is rising, the sun is bathing, and the whole city is like a group of picture scrolls, which is beautiful. ”

It's been four days later, and the footage of the magic city, including the rooftop, the airport, the train, and the hotel, has been filmed. At the same time, the photography team has also completed the overlooking shot of the city, and Huang Yuetai is now showing the results, playing a group of copies.

"Look at this group again, it is an aerial shot at night, thousands of lights are collected in one set of shots, the two most beautiful moments in the magic capital, all have not been missed, put in the movie, it can definitely greatly increase the texture of the picture. Oh, and this set of bullet train situation shots, the momentum is very powerful, look at this, is it an aerial shot of the Huangpu River, like a jade belt, interspersed in the city? ”

"Very good results, so much material, enough material for me to edit into the film. By the way, have you shown it to the people in the city hall? ”

"Wang Wei sent it, and the city government also wanted to keep a set of copies, but for the sake of safety, we didn't agree, meaning to wait for the movie to be released and send it over."

"It's right to be on the safe side." Shao Shuaijun nodded, "By the way, Lao Huang, I heard that you and Bob have been studying high-speed lenses lately, how is the research, call the photography team over, let's do an experiment?" ”

High-speed photography technology is used in the shooting of high-speed lenses, and the so-called high-speed photography is simple and simple, but it is not simple to say that it is not simple.

The human eye's ability to distinguish time is only 1/24s. In other words, we can see 24 sets of images in one second. To put it simply, we see 24 images in one second, which make up the action we see. But the movement is not continuous, there are countless groups of static movements, such as throwing a knife, you may only see the knife flashing, in fact, the knife is more movement trail left, trapped in the human eye's ability to distinguish, invisible.

Therefore, the frequency of cinematography and projection is 24 frames/s, and 24 frames flash in one second. It allows us to get the feeling that the movie is continuous, and the characters are moving all the time without pause. But a lot of objects moving at high speeds. Or transient phenomena, we can't see clearly.

And high-speed photography is to clearly present this kind of change that is not visible to the human eye. It is a photographic method that shoots quickly and has a short exposure time. The human eye can only "see" 24 images in one second. High-speed cameras can see hundreds, thousands, tens of thousands, or even hundreds of thousands, or millions of images in a second. It is then exposed on the negative. After rinsing and decompressing, it is played according to 24 frames per second, and so on. People can see this change clearly.

A typical application of high-speed photography is bullet time. The bullet passes by in an instant, but it can be greatly extended in the movie to give a strong visual conflict. Shao Shuaijun has always been very eager for this kind of application, and now that he has the opportunity, he naturally has to study hard.

Especially in Inception, the time of the dream is different from the time of reality, and five minutes of reality equals one hour of dreaming. In order to achieve this kind of temporal contrast, high-speed photography is a very good way to clearly present the temporality.

"The perfect combination of an HDCAM-SR high-speed camera and a Photo-Sonics-4ER lens. Let's start with a high-speed shot of an apple in the water? "Bob. Adams is civilizing while assembling the camera. This kind of camera is a high-speed camera that is professionally used for film.

High-speed cameras were originally used in scientific research and military applications to record small or difficult experimental phenomena to be captured by the naked eye, and there are many categories. The principle is splitter type, optoelectronic type, the result is divided into scanning camera, frame camera, and the shooting speed is divided into medium and low speed, high speed, and ultra-high speed. The one we are using today is an opto-mechanical ultra-high-speed frame camera.

Simple and effective.

"It's good, it's good, I've turned on the camera and the lens is clear. Very well, Hatton, drop the apples! ”

Creak!

The sound of the camera running is clearly audible, crackling, apples entering the water, and splashing in all directions.

Then a group of people took the film, went to develop and process, and about half an hour later, the copy came out. Shown on a small device, the picture is clearly presented.

An apple slowly fell into the water, as if it had smashed a circular pit on the surface of the water, and it was like a flower suddenly blooming on the surface of the water. The movement trajectory of water droplets is clear and clear.

"Wow! Very beautiful! Shao Shuaijun admired.

"I can already think of waiting for Leo to fall into the water, just like this big apple, to make the water in the bathtub blossom and bear fruit, haha." Assistant director Inst laughed.

Bob looked calm: "It's not enough, the exposure amplitude of high-speed photography needs to be corrected, and the light this time obviously doesn't match the tone I want, nor does it fit the dream-level picture sense you said the director." ”

"Inception" is very complicated, and even some viewers may not know which layer of dream they are in. Even the actors in the crew are often confused about which play they are playing now. Therefore, Shao Shuaijun has set strict photographic standards, and the main colors of different dreams must be distinguished.

For example, in the opening scene of the script design, in the palace of the golden dragon, the color color required is nostalgic, so the lighting and character dialogues of the shooting must conform to this main color. Then I fell back to the first layer of dreams, which was in the mistress's nest secretly built by the golden dragon, so the tone was fiery, and then back to reality, it was a cold tone, so that people could see at a glance how many layers of dreams they were seeing.

"Bob, we're going to shoot in the palace tomorrow, let's put these experiments aside for a while. This section of the palace requires us to shoot with our hearts, and it also lays a tone for future shooting. The collapse of the building, the destruction of the stone statue, etc., all require the cooperation of your camera crew and special effects team, and there is also a scene of heavy water washing, we had better pass through it at once. ”

There's a magical shot in the palace where Leo is pushed into the bathtub and the reality affects the dream. As a result, in the dream he was in, a huge flood flooded the entire palace.

In order to achieve this effect, Shao Shuaijun and the props team have already discussed, prepared about 20 tons of water, packed it in a box, arranged it at the window of the palace, and then poured it uniformly, simulating the scene of the water washing. It is conceivable that after so much water is re-washed, the rudimentary palace will inevitably be devastated.

If the lens fails, it will take time and effort to reshoot.

It can be said that this shot can only succeed and not fail. (To be continued......)
