Is the digital SLR camera used in the studio or a general digital camera?

I worked there for some time. I have a professional SLR camera for wedding photography and photography, and a small camera (also quite professional) for taking one-inch photos. If I go out to take photos, I will use a small camera, which is convenient and enough. If I go out to take a group photo, I will bring a big camera. After all, the shutter of a SLR camera has a service life. The small camera here is also digital, and no one uses film now unless the customer requests it.

In the working system of SLR digital camera, after the light reaches the reflector through the lens, it is refracted to the focusing screen above to form an image. Through the eyepiece and pentaprism, we can see the scenery outside in the observation window. In contrast, ordinary digital cameras can only see the captured images through the LCD screen or electronic viewfinder (EVF). Obviously, the directly seen image is more conducive to shooting than the processed image. When shooting in DSLR, press the shutter button, the reflector will pop up, and the shutter curtain in front of the photosensitive element (CCD or CMOS) will be opened at the same time, and the light passing through the lens will be projected onto the photosensitive original, and then the rear reflector will be restored immediately, and the image can be seen in the viewfinder. This structure of the single-lens reflex camera ensures that it is shot through the lens, so that the image seen in the viewfinder is always consistent with the image on the film, and its framing range is basically consistent with the actual shooting range, which is very conducive to intuitive framing and composition. A major feature of SLR digital cameras is that they can change lenses of different specifications, which is the inherent advantage of SLR cameras and the great limitation of ordinary digital cameras. For people who play photography. Match the lens. It can be said that with your right hand and left hand, you have to shoot different things with different lenses. Such as telephoto, defocus, wide angle and fisheye. Wait a minute. The general digital camera is a special camera, which can shoot and convert the shot scene into an image stored in digital format through internal processing. Different from ordinary cameras, digital cameras do not use film, but use fixed or detachable semiconductor memory to save the collected images. A digital camera can be directly connected to a computer, TV or printer. Under some conditions, digital cameras can also be directly connected to mobile phones or handheld computers. Because the image is processed internally, users can immediately check whether the image is correct, and can immediately print it out or send it by email.
