What does the f-stop in a digital camera mean? Do you mean the aperture value of? Who can answer in detail ~TKS!

What does the f-s in a digital camera mean? Does it mean the aperture value? Who can give a detailed answer ~TKS! ! !

is the aperture number (or aperture value: F-number), such as:

f/1, f/1.4, f/2, f/2.8, f/4, f/5.6, f/8, f/11, f/16, f/22, f/6. What is the aperture in a digital SLR camera?

The aperture is like a window of a room. The larger the window, the greater the amount of light coming in, and the smaller the window, the smaller the amount of light coming in. The aperture can be adjusted to match the shutter speed to control the exposure.

Under the same shooting conditions and the same lens focal length, there are many exposure combinations, such as large aperture and high shutter speed; The aperture is small and the shutter speed is low. What does DDC in a digital camera mean?

It's CCD, the photosensitive element, which is equivalent to the film of an old camera. Now it is basically replaced by CMOS. What does CCD in digital camera mean?

it should be the same as an optical camera, right? But I don't think it's necessary to change the shutter speed since there is an adjustable photosensitive function.

There is an aperture in the function of a digital camera from F to F. What does F mean?

F (in capital) refers to the aperture value, and F (in lowercase) refers to the focal length.

The aperture value is 1, 1.4, 2, 2.8, 4, 5.6, 8, 11, 16 and 22. The less light enters

The commonly used lenses with aperture values of 2.8, 4, 5.6, 8, 11, 16 and 22

The lenses with aperture values of 1, 1.4 and 2 are quite expensive! What does AE in SLR digital camera mean?

AE: automatic exposure

—————————————————————————————

AE is called Auto Exposure, that is, automatic exposure. Aperture priority AE mode is an automatic exposure mode in which the photographer manually selects the aperture size when shooting, and the camera automatically selects the shutter time required for appropriate exposure according to the scene brightness, CCD sensitivity and artificially selected aperture, that is, the exposure mode in which the aperture is manual and the shutter time is automatic. This exposure method is mainly used in shooting occasions where depth of field needs to be given priority, such as shooting landscapes, portraits or macro photography.

——————————————————————

AE modes can be roughly divided into four types: aperture priority AE, shutter speed priority AE, program AE and depth of field priority AE.

aperture priority AE is an automatic exposure mode, in which the photographer manually selects the aperture size when shooting, and then the camera automatically selects the shutter speed required for proper exposure according to the brightness of the scene, the sensitivity of the film or CCD, the artificially pre-selected aperture and other information. Simply put, it is an exposure mode of "manual aperture and automatic shutter speed". The advantage of aperture-priority automatic exposure is that the photographer can control the depth of field according to his needs, so this exposure method is mainly used in shooting occasions where the depth of field needs to be given priority, such as shooting landscapes, portraits or macro photography. When using aperture priority automatic exposure, the preview function of depth of field on the camera is effective, and it is also effective when adding various close-up accessories and reflective lenses, but the effect will not be ideal when shooting moving objects, TV pictures and computer pictures.

shutter speed priority AE mode is an exposure mode in which the camera automatically selects the aperture size needed to obtain correct exposure according to photometric information, CCD sensitivity and artificially set shutter speed, that is, "shutter speed is manually adjusted and aperture is automatically set". In this mode, the shutter speed manually selected and the aperture coefficient automatically set by the camera will be displayed on the LCD screen or the camera.

programmed AE exposure (p) is an automatic exposure mode in which the aperture and shutter speed are automatically adjusted by the camera according to the program. This exposure mode is widely used in mobile cameras (that is, fool cameras).

AE mode with priority of depth of field, also known as DEP, is an automatic exposure mode with priority of depth of field, especially suitable for taking group photos and landscape photos. This priority exposure mode is unique to Canon cameras. What does wide-angle shooting in a digital camera mean?

Generally, wide-angle shooting refers to the lens, such as our eyes. If we see an angle of about 5 degrees, it is called the header. If we see it more widely, if SJCAM sports camera has a wide angle of 17 degrees, the angle will be wider. What do you mean by CCD in scanners and digital cameras?

to put it simply, it is the photosensitive element. The CCD of the camera is rectangular, while that of the scanner is linear. A plurality of unit CCDs are integrated on it, and when in use, the received images are digitized and transmitted to a computer to form an image file.

the scientific name of CCD is charge coupler, and it is enough for users to have a general understanding of its working principle. What does the IMEI number in the mobile phone refer to?

the global communication identification code, referred to as "serial number" for short, is just like a person's ID card. Every mobile phone has an independent serial number, and the same mobile phone in the world does not have the same IMEI code, which is also to prevent people from renovating and counterfeiting.
