When photography technology first started, the negatives were made of metal, and later they were made of glass. They could only take one picture at a time and could not take images of continuous motion. It was not until 1888 that Eastman Kodak invented film based on gelatin that it became possible to take images of continuous motion. The film was invented and became a great art form.

The standard frame rate of contemporary movies is 24 frames per second, that is, 24 photos are played every second. However, the movie was not 24 frames per second at the beginning. Due to the technical limitations of early cameras and photosensitive films, the frame rate of the movie was only 12 frames per second at the beginning, so it seemed very "stuttered". But this gradually became a symbol and film effect of early movies, such as the famous Chaplin movie, which actually became part of the comedy effect. Later, with the continuous development of photography technology, films could sense light, exposure, and electric reels instead of artificial reels. The shooting and playback speed of the film continued to increase, and finally reached a lower limit for the human eye to watch the moving picture without feeling stuttered: 24 frames per second, and became the playback standard of the movie.

To this day, more than half of the film playback equipment in the world operates according to this standard. At the same time, the film size of the photograph has multiple specifications, which also affects the film specifications of the camera. Later, 35mm film became a standard, and most movie cameras also used this as the standard, namely, 35mm movie camera. The standard 35mm movie camera roll box (filling iron box) contains 122 meters or 305 meters of film, which can be shot for up to 10 minutes. This kind of film camera is very heavy and can only be placed on a stand for shooting. In order to make the camera lighter and miniaturize, the film specifications have developed into 16 mm and 8 mm. The film camera has become smaller, and handheld photography has begun to be introduced into film shooting, which has affected the expression of the film lens language.

But it is undeniable that the advantages of film cameras are also obvious: the picture is delicate, the colors are natural, and suitable for the big screen. The texture of film cameras is the real movie taste. However, the disadvantages of film cameras are also very troublesome. First, the cost is very high. Film is a disposable product, which cannot be used repeatedly, and is easily damaged. Second, the shooting process is complicated, and the film exposure must be relatively accurate. The previous focus and metering process affects the efficiency of film shooting and lengthens the production cycle, which also increases the cost of making movies; Third, a box of film has limited length, and after shooting, it must be shut down and replaced, which limits the shooting of super-long lenses of the movie; Fourth, it limits the projection scenes and equipment. To truly play the film shot, it can only be performed on the film projector.

However, color cameras are very simple to use. Usually, they can work by installing the lens correctly, connecting the signal cable, and turning on the power supply.

Pornography, which could only be expressed in novels and paintings, has been "eye-opening" by new technologies for people in the 20th century. In 1839, the Parisians invented the silver-print photography method, and a month later, the first photo of naked women appeared on the market. During the American Civil War in 1861, soldiers often asked their families to mail yellow books and pornographic photos to relieve their physiological pain, which led to Congress passing laws prohibiting the delivery of obscene materials by mail. In 1874, London police found 130,000 pornographic photos at the home of a photographer...

Pornography in text and pictures also requires the blessing of imagination. With the direct image, the pornography industry can be called "like a tiger's wings".

So when did porn movies appear?

When will the movie be invented, and when will the pornographic movie appear?

In 1896, it was considered the birth year of the pornographic film. Eight months after the invention of the camera, French director Eugène Pirou made the short film "Le Coucher de la Mariée", which included the heroine's striptease scenes, divided into "Softcore" movies. The original length was 7 minutes, but the final editing was less than 2 minutes. In 1908, the first "Hardcore" movie "A l'écu d'or ou la bonne auberge" was also born in the hands of the French. Two years later, another hard pornographic film "Am Abend" was completed in Germany, and the "back-entry" shot appeared for the first time in the movie.

In other words, whether it is a soft porn movie that "a soaked T-shirt is more sexy than a naked body" or a hard porn movie that is "full of nude, tied up and abused", it has been a long half century from its birth date to World War II.

So when he reached out to open the door, Mrs. Katy, the colo casting assistant director, was slowly awakened. The clock had quietly arrived on November 9, 1943, at 11:07 p.m.

The whole TV wall composed of a 5-inch E1 TV set.

In fact, the full name of the 50 5-inch E1 TVs sold publicly on September 1, 1939 was "E1 Radio TV". The whole is divided into two parts. On the right is a 5-inch TV display screen, and on the left is a similar-sized broadcast receiver (radio). In addition, the necessary frame and edges are required, so the combined size is more than 10 inches.

And every pocket TV on the spliced ​​TV wall in front of you is the smallest 5-inch E1 TV set. So there is only image, no sound.

As the sight gradually adapted to the dark confined space and a whole bright TV wall, the "live broadcast images" in progress became clearer.

As she guessed in Room 2. This is a special indoor scene - the shooting scene of the "bed scene".

All female stars who are full of boiling passion and sexual tension in front of hidden shots are real guns and ammunitions "fighting real soldiers". And there is no live broadcast scene with NG (the abbreviation of the film term Not Good, which refers to the scene where actors make mistakes or laugh during the shooting process or fail to achieve the best effect. Some also use it as a trailer for the ending to attract audiences and let everyone understand the unknown side of the shooting process).

Just as the casting assistant director Mrs. Katy was deeply attracted by the male and female protagonists in the E1 TV set with different shooting angles on the entire TV wall, she was suddenly blocked by her feet wearing leather hotel slippers.

Looking up the leather hotel slippers and nylon suit socks, the "muscle" man wrapped in pajamas and wired headphones was the "head of state" who was just like a fake one.

"Hi! Hitler." Mrs. Katy, the casting assistant director who couldn't struggle to get up for a while, sat down and gave a Nazi ceremony.

"Shh—" "The Head of the Head" made a low-key gesture: "You are right, Katie."

"What, what?" Mrs. Katy, the casting assistant director who was so nervous that he was dying, didn't react at all.

"The Anti-Landing Battle of Sicily." The "Full Head" who was faked to change is about the video he and Mrs. Katie had at the Gestapo headquarters a few months ago.

"Ah... it turns out you are talking about this." For some reason, Mrs. Katy, the deputy director of casting, suddenly felt that her plot seemed to have a turnaround: "Fortunately, we have a good ending."

"Ah, ha!" The expression of "Fueror of the First Nations" who was so fake, exuded a lot of self-deprecating: "Tell me what you think."

"What?" As the most famous lady of Salon in Berlin's upper-class social circle, the casting deputy director Mrs. Katy seemed to have grasped the head of the idea.

"About the performance tonight." The "First of the Head" who was replaced by a gun exposed when he raised his hand, which had been hidden in the sleeve of the nightgown, knocked on the wired headphones on the side.
