Which gear does the camera use?

What do P files and S files on the camera mean?

P is the abbreviation of English Program, that is, program priority mode; And s is the abbreviation of Shutter, which is shutter priority mode. P belongs to the program mode in full automation. Usually, today's cameras provide dozens of different scene modes for you to choose from. For example, night mode, snow mode and seaside mode. The camera will adjust the aperture, shutter and ISO according to the scene you choose. For example, if you choose night mode, the camera will automatically slow down the shutter and increase the aperture. Most cameras have the function of intelligently distinguishing scenes, that is, when you switch to P mode, the camera will automatically guess the current scene, and then automatically adjust the shutter according to the amount of light to reach the normal exposure mode.

S is a semi-automatic mode (some cameras use T file or Ts file), which means that you adjust the shutter speed you want, and the camera automatically adjusts the aperture size and ISO to achieve normal exposure. The other is that mode A is the abbreviation of Aperture, that is, the aperture size. This semi-automatic means that you choose the aperture size you want, and the camera automatically adjusts the shutter and ISO.

All these different files are needed, because on a normal rainy day, if you choose P mode, the photos you get will be normal rainy days. However, if you want to capture the moment of water droplets in the air, you need to use S mode, because you need the speed of11000 seconds. But if you want to shoot a series of water droplets into a thin water column, then the speed you need is about115 seconds. Automatic p mode may automatically select 1/250 seconds according to the light, so that you won't get other effects.

Therefore, the P file is fully automatic; S file belongs to semi-automatic exposure mode.

The camera gear function is introduced as follows:

1, automatic. Auto automatic gear is the most commonly used gear for beginners. This gear can be used as a "fool" gear, which is the most convenient and worry-free to use. When taking a photo, you only need to compose a picture in the viewfinder and press the shutter, so you can basically get an accurate exposure photo, regardless of the shutter speed, aperture size, sensitivity value and other parameters.

2, P file. P file can be regarded as an upgrade of Auto file. Compared with automatic documents, cameras handle all exposures. After automatically selecting a combination of speed and aperture, P-file can also manually control exposure through exposure compensation, which is a little manual function added on the basis of full automation. If the exposure compensation is set to 0 when shooting, there is no difference between the P file and the automatic file when shooting.

3. File A. The Chinese name of file A is aperture priority, which is the camera gear used by most users at present. When shooting with camera A, the camera mainly controls the aperture size of the lens, and the camera will choose the appropriate speed for exposure according to the selected aperture size. The biggest advantage of the file is to control the contraction of the lens aperture and the depth of field of the photo. For many users who like to shoot large aperture and shallow depth of field, a file is easier to realize. In addition, a file can also control exposure compensation and sensitivity to control camera exposure, which is very suitable for daily shooting.

4, S file. The Chinese name of S file is shutter priority. Just like A-file, choose the appropriate shutter speed when shooting, and the camera chooses the appropriate aperture for exposure according to the shutter speed. The biggest advantage of S file is to control the shutter speed to shoot high-speed moving objects, such as fast-moving objects, sports themes, wild animals and so on. It is easier to complete shooting by setting a high-speed shutter with S file.

5, M file. M gear is a fully manual gear, which is the gear most used by photographers. According to the optical environment of the shooting scene, the M file needs to manually select the aperture and adjust the shutter speed to shoot, so as to obtain accurate exposure photos. M file is a test of the photographer's experience. Through the combination of M-stop aperture and shutter, the camera exposure can be controlled more accurately and the desired effect can be obtained.

Is SLR a file or S file for daily photography?

Generally speaking, the first gear is used more, and adjusting the aperture can effectively control the depth of field.

When shooting sports themes, S files are generally used, which can control the shutter speed and satisfy the shooting creativity. For example, high-speed shutter is used to solidify the motion moment, and low-speed shutter is used to cause motion blur effect to express the motion.

Digital SLR camera is a single-lens reflex digital camera, abbreviated as SLR(singlensreflex). This technology is to install a mirror at a 45 angle in front of the film plane, and there are frosted glass and pentaprism eyepiece above the mirror in turn. The pentaprism reflects the real image light many times to change the optical path, and sends the image to the eyepiece, so that the image seen in the observation window is always consistent with the image on the film, and the shooting range is basically the same as the actual shooting range. The unique design of this prism enables the photographer to directly observe the image passing through the lens from the viewfinder.

Representative models in the market are common in Nikon, Canon, Pentax, Fuji and so on. In the early days, this kind of camera was generally big and heavy.

Single lens reflex (SLR) is the most popular viewfinder system, which is used by most 35mm cameras. In this system, the unique design of the mirror and prism enables the photographer to directly observe the image passing through the lens from the viewfinder. Therefore, you can accurately see the same image that the film is about to "see".

Excuse me, what is the use of P, S, M and A files on SLR cameras?

1, P-file automatic exposure mode: Generally speaking, choosing P-file program automatic exposure mode is a simple, fast and reliable way. When shooting indoors in low light, the built-in flash of the camera will automatically jump up and stand by. If you want to shoot in pure natural light, you can turn off the flash, and it will automatically combine into "big aperture and fast speed" as much as possible to prevent the image from blurring at slow speed.

When shooting in outdoor strong light, it will combine a smaller aperture with a higher shutter speed. At this time, you can turn on the built-in flash of the camera and use it as an auxiliary light for people when shooting in backlight. Some cameras also have an automatic exposure mode of "small aperture, low speed" in the P-file program.

2.A-stop aperture priority mode: A-stop aperture priority mode is also a depth-of-field priority automatic exposure combination. In photography, this method is adopted by most photographers. Because when selecting files, you can control the depth of field by adjusting the aperture size to show the relationship between virtual and real works. For example, taking landscape photos, using a smaller aperture (above F 1 1 or above F 16) can make all the scenes in the picture very clear and the image quality of the picture is also very high.

If it is necessary to highlight the subject and blur the background when shooting close-ups of portraits or other scenes, you can set a larger aperture to shoot. As for the exposure control, there is no need to worry, because in the process of adjusting the aperture, it will automatically track and set the corresponding shutter speed with the change of the aperture size to ensure accurate exposure.

3.S-speed priority mode: S-speed priority mode is generally used when shooting moving or high-speed moving objects, which requires a high-speed shutter to capture clear motion moments without a large depth of field. For example, when shooting track and field, ball games and other sports, the shutter speed should be at least 1/250 seconds or 1/500 seconds or even faster to ensure the clarity of the instantaneous image.

4.M-range manual control mode: M-range manual control mode is to manually adjust the shutter speed and aperture size, which is a bit complicated, less convenient than P, A and S modes, and not easy to capture, so it is rarely used at present.

You only need to use the flash as the auxiliary light to shoot the backlit portrait in natural light, and the natural environment requires accurate exposure; Or shooting portraits under night light requires both proper exposure of the face and correct exposure of the night background. This requires taking into account the flash index and the distance between people, taking into account the aperture size and the appropriate shutter speed to achieve the best of both worlds.

Singlensreflexcamera(SLR camera) is also called SLR camera. Refers to a camera that uses a single lens, through which light shines on the reflector and takes a view through reflection.

The so-called "single lens" means that the photographic exposure light path and the framing light path * * * use one lens, unlike the paraxial camera or the double-reflex camera, the framing light path has an independent lens. "Reflection" means that a plane mirror in the camera separates the two light paths: when taking a view, the mirror falls, reflecting the light of the lens to the pentaprism and then to the viewing window; When shooting, lift the reflector quickly, and the light can shine on the film or photosensitive element CMOS or CCD.

Not all DSLR are high-end products.

2006 was the year when the DSLR war broke out in an all-round way. In this year, Sony, Samsung and Panasonic entered the DSLR market collectively, while traditional manufacturers such as Olympus, Nikon and Pentax also came up with their latest low-priced products to deal with it, which intensified product competition on the one hand and greatly enriched consumers' choices on the other hand, further reducing the price of entry-level DSLR to freezing point.

Although there are tens of thousands of high-end DSLR products, entry-level DSLR packages with lenses below 6000 yuan and single bodies below 5000 yuan abound, and this price is no longer a high-end product.

This price has almost reached the defense line of high-end consumer digital cameras. It can be said that the price difference between DSLR and high-end consumer cameras is not obvious, which will directly shake the choice of some consumers who originally planned to buy consumer cameras. Although DSLR is slightly larger than high-end consumer cameras, the control and imaging quality of DSLR have made a qualitative leap.

In addition, different lenses can be replaced as needed, which constitutes the absolute temptation of DSLR single-lens reflex camera. Consumer-grade cameras with the most choices of 2000 ~ 3000 yuan, although the imaging quality is also remarkable, are not comparable to DSLR at all.

What do the AV files, M files and TV files of the camera mean? What is the difference?

AV is aperture priority, that is, you set the lens aperture value yourself, others are camera automatic, TV is shutter priority, you set the shutter value yourself, others are automatic. M gear is fully manual, and the aperture, shutter and sensitivity are all set by yourself. Most photographers like to use M-block, because the camera listens to itself completely, and the automation is sometimes inaccurate.

A gear is aperture priority mode-adjust aperture-speed changes automatically.

T range is the shutter priority mode-adjust the shutter-the aperture changes automatically.

M-aperture and shutter should be adjusted manually.

P-range is a fully automatic combination mode of shutter and aperture.

Auto-the simplest automatic gear, regardless of anything, just press the shutter!

Let me give you an example (in fact, it is also an example in the manual, hehe): For example, if you want to photograph the water in the fountain and capture the moment when the water solidifies, you can use the shutter first, and then you can capture the solidification state of the water. If you want to shoot the flowing lines of water, you can also use the shutter first and slow the shutter, but if the shutter is slow, you need an iron hand. Then why not use the aperture to worry first? Because it is not easy to adjust, it is not easy to grasp the speed of the shutter when you want to shoot the moment when the water solidifies, so you usually use the shutter first.

In the usual shutter priority mode, that is, TV mode.

Aperture priority mode and AV mode can capture the depth of field of photos. The larger the aperture, the smaller the depth of field, and the smaller the aperture, the greater the depth of field. The larger the aperture, the smaller the f value. On the contrary, the larger the f value, the smaller the aperture. The smaller the depth of field, the greater the background blur, and the greater the depth of field, the smaller the background blur.

M file is to adjust the aperture and shutter by itself, and the exposure compensation is to be adjusted by the camera itself, which requires certain accurate exposure experience.

I use AV and m more myself. (Maybe M will be a little more, hehe)
