What does the shutter of a digital camera mean???

1 1000s refers to thousandths of a second.

The shutter is a door-like device inside the camera that opens and closes quickly to determine how much light enters.

The general time is between 30 seconds and 8000th of a second, depending on the lighting conditions and the photographer's intentions.

1 for 1, 1000 for 1000, for division or semicolon, and s for seconds.

All that is, divide 1 second into 1000 parts, and 1 part of them is 1000th of a second. Clear?

If it's 2 1000s, that's 2 thousandths of a second, that's 1 500s, and the shutter is lowered by 1 stop. And so on.

More than 1 cent or more than 2 cents? Of course it's 2 points, so 1 500 = 2 1000 > 1 1000

Is it simple enough?

Shutter priority means that the machine's automatic metering system calculates the value of **, and then automatically determines how wide aperture to use based on the shutter speed you select.

1 1000s is a thousandth of a second, and you can imagine that the speed is very fast, hehe, this speed seems to be able to shoot a bullet

1 1000s and 1 500s are fast??? Of course, it's 1 1000s fast, but it's hard for the average home camera to reach this speed in automatic mode, and it's okay to shoot the sun haha, but the unit price is the lens coating and CCD

1 1000s is a thousandth of a second.

Let's explain it to the landlord in the most popular way:

1 1000s shutter: The time between the opening and closing of the shutter is one thousandth of a second, that is, the time for light to enter the sensor is one thousandth of a second.

In other words, when taking photos with this shutter value, the ambient lighting situation is so good that it only takes a thousandth of a second to sensitize the light. When the light is bad, the shutter value becomes longer, and the sensitivity time is longer. For example, sometimes when shooting night scenes, the shutter should be more than 1 second.

Meaning of shutter in camera:

The shutter is a device in front of the lens that blocks light from entering, and generally speaking, the larger the shutter time range, the better.

The shutter of the camera is a "door" that allows light to pass through, and the light is reflected quickly by film, etc., and a good image can be formed only when the appropriate opening and closing time is appropriate. The time is short, and the sensitivity time is insufficient to form a clear image. After a long time, the light sensitivity is excessive, and the level and details of the image cannot be expressed.

The door is usually closed, but when we adjust the camera through the viewfinder and press the shutter, the film has already recorded the scene we want to capture.

Extended Material: Cameras

A camera, abbreviated as a camera, is a device that uses the principle of optical imaging to form an image and record it with a negative. Many devices that can record images have the characteristics of a camera. Medical imaging equipment, astronomical observation equipment, etc.

A camera is an optical device used for photography. After the light reflected by the subject is focused through the photographic lens (camera objective) and the shutter that controls the amount of **, the subject forms a latent image on the photosensitive material in the camera obscura, and then processes (i.e., developing, fixing) to form a permanent image, which is called photography. It is divided into general photography and professional videography.

A digital camera is a type of camera that uses an electronic sensor to convert optical images into electronic data. Unlike ordinary cameras, which rely on the chemical changes of silver bromide on film to record images, the sensor of digital cameras is an optically inductive charge-coupled (CCD) or complementary metal-oxide-semiconductor (CMOS). Before the image is transferred to a computer, it is usually stored in a digital storage device (usually using flash memory; Floppy disks and rewritable discs (CD-RW) are rarely used in digital camera equipment).

Digital cameras are optical, mechanical, and electronic products. It integrates the conversion, storage and transmission of image information, and has the characteristics of digital access mode, interactive processing with computer and real-time shooting. Digital cameras first appeared in the United States, more than 20 years ago, the United States used it to transmit to the ground via satellite**, and later digital photography turned to civilian use and continued to expand the scope of application.

Shutter meaning: An accessory device on a camera that comes in various forms (e.g., rotary, variable diaphragm, or focal plane shutter) that opens and closes the diaphragm to make the film or photosensitive plate shine**.

Pronunciation: [kuài mén].

Phonetic: Part of speech: noun.

Structure: Fast (left and right structure) gate (monolithic structure).

Chinese dictionary: A mechanism that controls ** time when taking photos. Due to the difference in opening and closing speed, the film can be moderately sensitized, or the subject's motion can be stilled on the film, resulting in a clear image. Vertical blue early.

The sentence formation of the shutter is as follows:

1. You will hardly find that Scorpio has too much praise or denigration for a journey, and the lack of joy and anger is a characteristic of this sign. When the big guys were overwhelmed by the beautiful scenery in front of them and their eyebrows fluttered, the scorpions just watched faintly, quietly pressing the camera shutter to record the scenery that only belonged to them.

2. A camera is a photographic device composed of a lens, a camera obscura, a shutter and other devices.

4. It seems to be pressed down by a pair of invisible hands, and there is a snap.

5, Sun Guotian was so excited that he almost suffocated, he held his breath, pressed the shutter continuously, and took this rare picture.

6. You also need to set a moderate shutter speed and aperture value according to the location of the storm.

The difference between the electronic shutter and the mechanical shutter lies in the principle that they control the shutter, the electronic shutter uses the principle of the circuit control shutter coil magnet to control the shutter time, and most of the gears and linkage parts are made of plastic; The principle of mechanical shutter control shutter is that the gear drives the control time, and the linkage and gear are mostly made of copper and iron. The former is easily damaged by the invasion of wind and sand, and the latter is also afraid of the erosion of wind and sand, but it is easy to clean.

And when it takes more than 1 second**, Gate B is used. When using the bulb, the shutter release button is pressed, and the shutter is opened for a long time until the release button is released, and the shutter is closed. This is a shutter specially set for long **.

The shutter works like this, in order to protect the sensor in the camera, the shutter is always closed; When shooting, after adjusting the shutter speed, just press and hold the shutter release button of the camera, between the opening and closing of the shutter, let the light through the photographic lens, so that the photosensitive film in the camera gets the correct **, and the light enters the image sensor through the shutter and is written to the memory card.

The shutter delay function is ideal for night shots.

When using a certain model of digital camera to shoot a scene, it is important to know the shutter speed first, because when you press the shutter, you can only capture vivid images if you take into account the shutter start time and know the timing of the shutter release.

Generally, the shutter speed of ordinary digital cameras is mostly within 1 1000 seconds, which can basically cope with most daily shooting. The shutter is not only "fast", but also "slow", which is the delay of the shutter, for example, some digital cameras have a shutter of up to 16 seconds, which is enough to shoot night scenes, but the shutter is too long will also increase the "noise" of the digital **, that is, there will be miscellaneous streaks in the **. As for the B-shutter function that is common in DSLR cameras, although you can freely decide the length of time** and have more shooting flexibility, most consumer digital cameras cannot support it at present, and at most provide slower speed defaults such as 2 seconds, 8 seconds, and 16 seconds.

The wear and tear of the camera shutter is more than 50,000 times for consumer machines and 80,000 to 100,000 times for professional machines.

The shutter life of a DSLR is limited, and this value tells you how long the camera will last.

For many friends who buy DSLR cameras online, it is very important to know the number of shutters of a DSLR or answer.

Almost brand new SLR or second-hand SLR, the camera's shutter counts and goes to the meaning of reference.

The real shutter life and use environment, use mode, maintenance degree and character have a certain relationship.

In the discussion post about the shutter life, I have the impression that one of the 400d took 140,000 shots before hanging up, which is much higher than its official shutter life.
