"Look at this, Hatton and I came up with this idea. We placed the imax camera on the top of the jet remote control aircraft and controlled the aircraft to take pictures from the Oriental Pearl Tower to Dongpu New District. Look at this set of scenery, the rising sun is bathing in sunshine
, the whole city is like a set of paintings, so beautiful."
It is already four days later, and the shots about the Magic City, including the shots on the rooftops, at the airport, on the train, and in the hotel, have been completed. At the same time, the photography team has also completed the overlooking shots of the city. Huang Yuetai is now showing off the results and playing a group of them.
A copy of the group.
"Looking at this sequence again, it is an aerial shot at night. Thousands of lights are captured in one shot. The two most beautiful moments in the Magic City are not missed. Putting them in the movie will definitely greatly increase the quality of the picture.
Oh, and there is also this set of shots of the train situation, which is very powerful. Look at this, it is an aerial shot of the Huangpu River. Does it look like a jade belt running through the city?"
"The effect is very good, so much material, enough for me to edit into the movie. By the way, have you shown it to the people in the city government?"
"Wang Wei sent it over, and the city government also wanted to keep a set of copies. For safety reasons, we didn't agree. We meant to wait until the movie is released before sending 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 recently at night. How is the research going? Call the camera team over and let's do it.
An experiment?”
High-speed photography requires the use of high-speed photography technology, and the so-called high-speed photography is easy to say, but not easy to say.
The time resolution of the human eye 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 actions we see. But movement
It is discontinuous and consists of countless groups of static actions. For example, throwing a flying knife, you may only see the flying knife passing by. In fact, the flying knife has more motion trajectories left behind, which is limited by the resolution of the human eye.
Just invisible.
Therefore, the frequency of film photography and projection is 24 frames/s, and 24 frames flash by in one second. This allows us to get the feeling that the movie is continuous and the characters are always moving without stopping. But there are many high-speed moving objects. Or
We cannot see the transient phenomenon clearly.
High-speed photography is to clearly present changes that are invisible to the human eye. It is a photography method that shoots very fast and has a short exposure time. The human eye can only "see" 24 images in one second.
A high-speed camera can see hundreds, thousands, tens of thousands or even hundreds of thousands or millions of frames in one second. Then it is exposed on the film. After development and decompression, it is played back at 24 frames per second, like this.
People can clearly see this change.
A very typical application of high-speed photography is bullet time. Bullets pass by instantly, but in movies, it can be greatly extended to give people a strong visual conflict. Shao Shuaijun has always been very eager for this application, and now
If you have the opportunity, you should naturally study hard.
Especially in "Inception", the time in dreams is different from the time in reality. Five minutes in reality is equal to one hour in dream. In order to achieve this kind of time comparison, high-speed photography is a very good way to present it clearly.
Out of time.
"hdcam-sr high-speed camera, photo-sonics-4er lens, a perfect combination. Let's first show a high-speed lens of an apple falling into water?" Bob Adams said while combining the camera. This kind of camera is professionally used
High speed camera for movies.
High-speed cameras were originally used for scientific research and military purposes. They are used to record tiny or experimental phenomena that are difficult to capture with the naked eye. They are classified into many categories. The principle is spectrometer type, the optoelectronic type, the result is divided into scanning camera, frame camera, and the shooting speed is divided into medium, low speed and high speed.
Ultra-high speed. The one we are using now is an optical-mechanical ultra-high-speed framing camera.
Simple and effective.
"Very good, very good, I have turned on the camera, the lens is very clear. Very good, Hatton, throw down the apple!"
Squeak!
The sound of the camera running is clearly audible, the popping sound, the apple falling into the water, and the water splashing everywhere.
Then a group of people took the film and went to develop and print it. In about half an hour, the copy was made. When it was projected on a small device, the picture appeared clearly.
An apple slowly fell into the water, as if it had made a circular pit in the water, or as if a flower suddenly bloomed on the water. The trajectory of the water droplets was clear and distinct.
"Wow! Very beautiful!" Shao Shuaijun praised.
"I can already imagine that when Leo falls into the water, he will be like this big apple, causing the water in the bathtub to bloom and bear fruit, haha." Assistant Director Inst laughed.
But Bob looked calm: "It's not enough. The exposure range of high-speed photography needs to be corrected. The light this time obviously does not meet the tone I want, nor does it meet the dream-like picture you mentioned, director."
"Inception" is very complicated, and some viewers may not even know which level of dream they are in. Even the actors on the crew are often confused about which part they are playing.
Therefore, Shao Shuaijun set strict photography 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 required tone is a nostalgic style, so the lighting materials, character dialogue, etc. must conform to this main color. Then fall back to the first level of dreamland, which is the secret building of the Golden Dragon.
In the mistress's nest, the colors are hot, and then back to reality, the colors are cool, so that people can clearly know at a glance which layer of dream they are seeing.
"Bob, we are going to shoot in the palace tomorrow. Let's put these experiments aside for a while. This part of the palace requires us to shoot carefully, and it also sets a tone for future shooting. The collapse of buildings, the destruction of stone statues, etc.
Etc., it all requires the cooperation of your photography team and special effects team, and there is also a scene of flooding, we'd better pass it in one go."
There is a very magical scene to be shown in the palace, that is, Leo is pushed into the bathtub, and the sense of reality affects the dream. As a result, in the dream where he is, a huge water floods the entire palace.
In order to achieve this effect, Shao Shuaijun and the props team have discussed and prepared about 20 tons of water, put it in boxes, arranged it at the windows of the palace, and then poured it uniformly to simulate the shot of a flood. As you can imagine, so much water
If you paint it again, the crudely built palace will inevitably suffer a devastating blow.
If there is a mistake in the lens, it will be time-consuming and laborious to re-shoot.
It can be said that this shot can only succeed and cannot fail. (To be continued, please search Piaotian Literature, the novel is better and updated faster!
