How does a DSLR camera work? What are the advantages? What is the best choice for an entry level mac

A DSLR camera is a camera that is reflexively viewed through a single lens.

Single-lens reflex cameras can be freely replaced with a variety of wide-angle, medium-focal length, telephoto or zoom lenses, and can also be fitted with close-up lenses, extension rings or telescopic cavities on the lenses as needed. In short, anything that can be seen clearly from the viewfinder can be captured by the camera. It is also possible to adjust various parameters for creative photography.

The best choice for entry-level machines is the Canon 600D.

If it is an ordinary small digital camera, just look at the brand, the quality of the big brand is ***, the second look is ***, you get what you pay for, this is the truth. Three look at the function, what special function is you need to find. Looking at the aperture of the lens, small DC is most prone to noise, and it is even more when the sensitivity is high, so the larger the aperture, the better the image quality.

If it's a DSLR, it depends on the style, Nikon's style, Canon's style, Pentax's style, Laika's style, Hasselblad's style, and Mamiya's style are all different, this is the color aspect; Second, it depends on the performance, the size of the sensor (whether it is full-frame, the larger the sensor, the better the noise control); Third, it depends on the processor, whether the continuous shooting speed meets the demand; Finally, look at the ease of use of the machine, whether it feels smooth to take it.

In addition, if it is a DSLR, it is also necessary to consider the lens, there are various types of lenses, there are wide angle (stretching effect, impact), standard (ordinary, but the aperture is generally larger, and the bokeh effect is good), telephoto (as the name suggests, of course, its bokeh effect is also very good, if the aperture can be large, it is better).

Finally, how much money does photography have to be budgeted for, the so-called "photography is poor for three generations, and drug abuse ruins a lifetime" ......So the donor is self-respecting, ah......

Back to the landlord's question,The principle of SLR is searched,So I directly recommend an entry-level to you.,Pentax KR,The cost performance of this machine is abusive to all other brands at the same level。

The full name of a DSLR camera is a single-lens reflex viewfinder camera, which refers to a camera that uses a single lens and is reflexively viewed through this lens. SoWhat are the advantages of a DSLR camera?Let's find out here.

What are the advantages of a DSLR camera

1. It is easy to change lenses, and can quickly change different lenses to meet different shooting needs;

2. The response is fast, and the time from pressing the shutter to recording to the screen is short. In the digital age, SLR cameras boot up fast;

4. There is almost no parallax, the range you see from the Naibi viewfinder is almost or even exactly the same as the range recorded by the image sensor;

5. The photosensitive original of digital SLR is generally larger than that of civilian DC. In other words, it is easier for DSLRs to record clearer images, and the noise is easier to control than civilian DCs;

6. It looks like it is stylish, giving people a sense of professionalism;

7. It is more power-saving than civilian DC, because the SLR camera only works in the gap between the shutter and the shutter is closed, unlike the civilian DC, as long as the image sensor is in the shooting mode, the sensor is in the working state, so the battery life of the SLR digital camera is stronger than that of the civilian DC.

That's all I have to offerWhat are the advantages of a DSLR camera, I hope it helps.

SLR stands for Single Lens Reflex, which is the most popular viewfinder system available today and is used in most 35mm cameras. 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 a result, the same image that the film is about to "see" can be seen accurately.

When shooting in DSLR, when the shutter button is pressed, the mirror pops up, and the shutter curtain in front of the image sensor (CCD or CMOS) opens at the same time, and the light through the lens Nikon D90 is projected onto the original sensor, and then the mirror immediately returns to its original shape, and the image can be seen in the viewing window again. This structure of the single-lens reflex camera determines that it is shot completely through the lens focus, it can make the image seen in the viewing window and the film forever the same, and its framing range is basically the same as the actual shooting range, which is very conducive to intuitive framing and composition. A great feature of DSLR digital cameras is that they can exchange lenses of different specifications, which is the inherent advantage of SLR cameras, which cannot be compared with ordinary digital cameras.

Now SLR digital cameras are positioned in the high-end products of digital cameras, so in the area of the image sensor (CCD or CMOS) related to the photographic quality of digital cameras, the area of SLR digital is much larger than that of ordinary digital cameras, which makes the photosensitive area of each pixel of DSLR digital cameras is also far greater than that of ordinary digital cameras, so each pixel can also show a more detailed brightness and color range, so that the photographic quality of SLR digital cameras is significantly higher than that of ordinary digital cameras. The heart of a DSLR system is a movable mirror that is placed at a 45° angle in front of the film plane. The light entering the lens is reflected upwards by the mirror onto a piece of ground glass.

To correct this defect, current eye-level SLR cameras have a pentaprism mounted on top of the ground glass. This kind of prism reflects the light several times to change the optical path, and sends the image to the eyepiece, at which point the image is upright and corrected left and right. When framing, most of the light entering the camera is reflected upwards by the mirror to the pentaprism, and almost all SLR cameras have a shutter directly in front of the film (called a focal plane shutter because it is in the film plane), and the shutter is closed when framing, so that no light reaches the film.

When the shutter button is pressed, the mirror quickly flips up to open the light path, and the shutter opens at the same time, so that the light reaches the film and the shot is completed. The mirrors in most cameras then reset immediately.

I don't copy, I tell you how I feel:

First of all, appearance: larger, pull the wind and look professional, attract the attention of others, and be professional.

Heavy body: increased stability, strong and durable shell. This is actually a disadvantage

Long service life: many shutter times, ranging from 5-100,000. Of course, there are usually less than 10 shots, very few.

Fast focus: Focusing, especially for news and sports, or taking pictures of children, weddings, focusing and shutter speed are too important.

Good image quality, large pixels: the ** of the SLR shoot can output a large format**, the picture is delicate, the color is rich, the color is accurate, and the depth of field is difficult to express.

Adapt to various environments: It can adapt to shooting under complex light conditions, and has strong adaptability to temperature.

All kinds of lenses: The fun of SLR is the lens, and the huge lens group can meet a variety of different shooting needs, sports, news, portraits, landscapes, etc., to experience the fun of SLR.

A DSLR is a complete system.

The difference between a DSLR and a regular digital camera is:

1 SLR interchangeable lens Ordinary digital cameras are not allowed.

2. The SLR viewfinder is an optical viewfinder, and an ordinary digital camera is a monitor viewfinder, and the disadvantage of the monitor viewfinder is that the color is distorted, the picture is delayed, and the screen cannot be seen clearly in the case of sufficient sunlight.

3. Single-shot control is stronger, can be more precise, free control**, while the general digital camera is uncontrollable, full point-and-shoot mode.

4. The DSLR (digital) sensor is larger, which means that in the case of high sensitivity**, the noise is less, the image quality is purer, the depth of field is shallower (the subject is real, the background is virtual), and the color contrast of the picture is better.

5. The shutter response is faster, while the shutter delay of a normal digital camera is very slow, and it is much slower in low-light situations.

6 Focusing System Not only in terms of focusing speed but also in focusing accuracy SLR is much more powerful than card.

7. White balance metering should be more accurate.

I won't talk about it more.

The card machine is easy to operate, a bit like a fool machine, there is no need to adjust too many parameters, and the size is small and easy to carry. A great feature of SLR digital cameras is that they can exchange lenses of different specifications, which is the innate advantage of SLR cameras, which is incomparable to ordinary digital cameras. One is CMOS and the other is CCD, and the imaging is naturally different.

DSLR's professional features: the advantages of the image sensor, the choice of lenses, the fast response speed, the excellent hand control ability, the abundant accessories, the use of professional flashes, and other auxiliary equipment to enhance its ability to adapt to various environments. For example, high-power flashes, ring macro flashes, battery grips, and timer remotes are a wide range of accessories that allow DSLRs to adapt to a variety of unique needs that are far inferior to ordinary digital cameras.

SLR is still to be honed for novices, and it can be pondered. What kind of lens is it, the effect of the background is blurred, etc

The tutorial of the SLR first looks at "New York Photography" There will be a lot of it It's a photography Bible-like textbook.

SLR: It is a lens with a reflector and an interchangeable lens The CCD size is larger than that of ordinary digital cameras, which is suitable for capture, creation, and ......

Ordinary digital cameras: easy to carry with you Lenses are not replaceable (except for mirrorless mirrors) Most of them are only suitable for home use.

Of course, the camera SLR is better, Canon EOS60D is recommended, with high configuration, clear imaging, and high cost performance, which is a mid-level nirvana product newly launched by Canon. In addition, the compact and lightweight nature of the 60D plastic body also reduces the burden on users when carrying the camera when going out.

SLR cameras are relatively professional cameras, and the image quality, shutter delay, etc. are faster than ordinary cameras. There are many adjustable parameters on the fuselage.

As for ordinary cameras, they are very automatic, pick them up and shoot, and there are fewer adjustable things, but because of the structure and cost, whether in terms of focusing speed, shutter delay, or imaging quality, they are not as good as SLR cameras.

If you only want to take photos at home, you can choose a regular camera, which is simple and lightweight.

But if you are interested in photography, you can choose a DSLR camera. Whether you are a family or a professional, the premise of using science is that you have some understanding of the terminology related to photography. In this way, you can judge how to shoot the desired scene.

Scientific use is to give full play to the various functions of the camera without using automatic mode.

SLR professional, ordinary, common people.

SLR refers to single-lens reflection, or SLR

The DSLR has a single lens for the entire imaging system (focusing and shooting).

There is no parallax, which means that framing and imaging are consistent. (Traditional cameras are mostly rangefinder viewing) Secondly, because an imaging system is used as a lens, the coordinated response is faster than that of ordinary machines, so the SLR camera is better for shooting objects moving at high speed (will not miss the good scene because of the slow response of the camera) Thirdly, the SLR machine uses different photographic systems due to the use of changing lenses, such as you can change the wide-angle lens, you can extend the lens, you can also add color films, you can also choose micro-distance lenses, etc., to meet your different needs. You won't miss out on the view because of the limited lens of the camera.

1. The biggest difference between a SLR camera and a point-and-shoot camera is that there are many lenses with different functions that can be replaced, while a point-and-shoot camera cannot;

2. The CCD size of the SLR camera is much larger than that of the point-and-shoot machine, which is the core component of the camera; For example, if we put the same scene on a large imager, it will be clearer when magnified than a small imager. Many times we have a misconception that the higher the pixel, the clearer it is, but we ignore the size of the CCD;

3. SLR lenses are the most important, different lenses have different fun, there are telephoto, fisheye, wide angle, etc. for selection, but they are all expensive;

DSLR cameras, single-lens reflex cameras. It has a lens swap function.
