What does DSLR mean in DSLR digital cameras

SLR refers to single lens reflex, or SLR (Single Lens Reflex).

In this system, the unique design of the mirrors and prisms allows the photographer to observe the image passing through the lens directly from the viewfinder. As you can see from the construction of a single-lens reflex camera, the light passing through the lens reaches the mirror, is refracted to the upper focusing screen and forms an image, and through the eyepiece and pentaprism, we can see the outside through the viewing window. When shooting, when the shutter button is pressed, the mirror pops up, and the shutter curtain in front of the film opens at the same time, and the light (image) through the lens is projected onto the film to make the film sensitive, and then the mirror immediately returns to its original state, and the image can be seen in the viewing window again.

This structure of the single-lens reflex camera determines that it is completely shot through the lens focus, it can make the image seen in the viewing window and the film forever the same, its framing range is basically the same as the actual shooting range, eliminating the parallax phenomenon of the rangefinder head-up framing camera, from the perspective of learning photography, it is very conducive to intuitive framing and composition. Another great feature of single-lens reflex cameras is that they can be swapped for lenses of different specifications.

DSLR cameras are called SLRs for the following reasons:

The full name of a DSLR camera is called "single-lens reflex camera".

Looking at the name, you should understand everything.

A DSLR is a single-lens reflex test camera, which is now one of the most popular viewfinder systems in the world, and many 35cm cameras use this viewfinder.

A DSLR camera is again his viewfinder named Full List Reflector Camera.

A DSLR camera is a camera that uses a single lens through which light hits the mirror and is viewed through the reflex.

The so-called single lens means that the photographic light path and the framing light path share a lens, unlike the rangefinder camera or double reflex camera with independent lenses for the framing light path. Reflection refers to a flat mirror inside the camera that separates the two light paths: the mirror falls down when framing, reflecting the light from the lens to the pentaprism.

When shooting, the mirror is quickly raised, and the light can hit the film or the image sensor CMOS or CCD.

If you don't require extremely high image quality, or if you are afraid of affecting the conditions of the subject, it is more reasonable to use a small digital camera when the lighting environment is not harsh. As an ordinary photography enthusiast, in the choice of image quality and portability, it determines the direction of choosing a camera, in fact, the most suitable for yourself is the best to buy a camera.

Therefore, some foreign journalists have picked up cameras with head-up framing and double shadow reconvergence and focusing, and they think that this kind of camera is small and lightweight, bright and quick to focus, and it is easy to grab the lens.

Camera care

Care and cleaning of lenses.

The lens is the most critical and fragile part of the camera, so you should pay great attention to the protection of the camera lens when using the camera, do not easily get dusted, let alone let the lens be touched by dirty hands, and only clean the lens when it is very necessary. When cleaning, it is best to blow off the dust with a balloon, or gently brush it off with a soft brush, if you encounter more stubborn dust, be sure to use a special lens cloth or lens paper to wipe it gently, remember not to use paper towels and other seemingly soft paper to clean the lens, because these papers contain wood pulp that is easy to scratch the coating, which will seriously damage the key coating on the camera lens.

LCD screen protection.

The color LCD screen is very easy to be scratched by hard objects, especially the color LCD screen without a protective film is more fragile, any scratch, will leave permanent traces, so when using, you can consider pasting the protective film of the handheld computer or mobile phone, which has a very good effect on protecting the color LCD screen. In addition to preventing scratches, special attention should also be paid to avoid the damage of high temperature to the color LCD screen, as the temperature rises, the color LCD screen will turn black, after reaching a certain temperature, even if the temperature drops to a normal state, the color LCD screen can not be recovered, resulting in irreparable damage.

1. The full name of a single-lens reflex camera is a single-lens reflex viewfinder camera, which specifically refers to a camera that uses a single lens and is reflexively viewed through this lens. The so-called single lens specifically refers to the fact that the ** optical path of photography and the framing optical path use a common lens, and unlike those double reflex cameras, they have their two independent lenses.

2. The reason why a DSLR camera is called a SLR is because it has a reflector inside it, and the shutter is also a mechanical mechanism, and the high-end model is also equipped with a pentaprism for framing.

Hello, I will answer for you what is the full name of the DSLR camera, what is the meaning of the SLR digital camera, I believe that many friends still don't know, now let's take a look..

Hello, I will answer for you about the full name of the digital Senni SLR camera, what is the meaning of the SLR digital camera, I believe that many friends do not know, now let's take a look!

1. SLR is a single-lens reflex camera, which means that the same lens is used for framing and shooting, and reflection means that the image is refracted through the mirror and seen by us.

2. SLR digital camera refers to single-lens reflex digital camera, that is, the English abbreviation of "digital digital, single single, lens lens, reflex reflector".

3. The representative models in the market are commonly found in Nikon, Canon, Pentax, Fujifilm, etc.

4. Another common point-and-shoot camera, the lens of framing and shooting is separated, the framing is usually in the upper right corner, directly seen through the viewfinder window, without a reflective device.

5. Advantages and disadvantages of the two: SLR framing shoots with a lens, and the framing picture is the picture on the **, while the fool-type is slightly different from the ** due to the position deviation; SLRs are bulkier and point-and-shoot are lighter; SLR is usually suitable for creation, and point-and-shoot is suitable for capture; The SLR can change the lens, but the point-and-shoot basically cannot.

6. Therefore, a good photography enthusiast usually has two kinds of cameras: SLR and point-and-shoot.
