DSLR camera technical problems, DSLR camera structure problems?

Of course, it is very important that the later stage of the SLR is very important, PS must be learned.

Of course, if you don't deal with it, you can still produce the film as long as you are not demanding about the effect.

Don't listen to their nonsense, photography mainly depends on shooting technology, and it will be good to shoot well without ps, and it is difficult to change good with ps if you don't shoot well.

There are many photographers who dare to shoot directly without post-production.

Of course, Yiduo is not pressing, you can still learn PS when you have time.

It's the digital age, and of course it's important, but if you're shooting well in the early stage, it's easy to process digitally, and vice versa, it's harder

Masters like to shoot directly ps is very useful but photography technology is the foundation these are very important but photography technology is the premise is the key to learn ps if you have time to learn ps.

Reminder: If you buy a SLR, you must be prepared to burn money, otherwise don't go to the SLR.

n Important. Almost all of the ** you see have been ps.

It's usually sharpened or something.

So that it looks more vivid, more colorful.

There's no need to say, "**You have to post-process to be so photogenic, and you can't do it without processing the effect", there was no photoshop before, so where did so many hand-me-down good** come from?

If you shoot well, you can do without ps, if the technology is too poor, no matter how much ps, it's useless.

Looking at the picture above, the left is the optical path of the SLR, the right is the optical path of the mirrorless mirror, you can see the focus sensor of the SLR, the pentaprism, etc., and the mirrorless camera concentrates all these on the image sensor, and the framing is replaced by an electronic viewfinder.

Focus using the contrast focusing method, or by using the phase focus unit directly to the image sensor.

These are advances in technology.

In fact, do you want to say that the technology of SLR can be replaced by mirrorless? I think from a technical point of view, the smaller size is definitely the general trend, after all, the development of technology; But at present, even for a long time, the SLR is still synonymous with high image quality and high technology, and it is still the main force of photographic art.

Just as the technology of the DSLR in the image sensor has not yet reached its peak, the mirrorless is far from reaching the level of being able to take charge of itself, and can be regarded as a qualified standby at most.

This necessary flipping action of the mirror also poses a number of other problems:

1. At the moment of shooting, the viewfinder will be blocked. Since the time blocked is only a matter of moments, this is not a major problem for mirrors that reset immediately. However, it raises some contingency questions.

For example, when shooting with a strobe flash, you will not be able to see through the viewfinder whether the strobe is shining properly.

Second, the noise of the mirror movement. This can become an important issue in places where quiet is required. Since there is no moving mirror in a rangefinder viewfinder camera that suddenly blocks the light path, this noise is not generated.

3. The vibration of the camera, that is, the overall movement of the camera caused by the flipping action of the reflector. Let's say you shoot with a shutter time of 1 500 seconds, then there is no need to worry. This tremor is not noticed.

However, if you shoot a precise picture with a long shutter time, such as when shooting with a telephoto lens in low light, this shaking can be problematic for imaging.

Fourth, there is another problem with using SLR framing. For example, if we want to shoot with a small aperture like F-32, and the light that f-32 allows to enter the lens is very weak, which will cause the image seen in the viewfinder to be dim and may be difficult to focus, or even impossible to focus at all.

Actually, the SLR solution is quite ingenious, it will use the maximum aperture of the lens to allow us to frame and focus, and when the shutter is pressed, the aperture of the lens will immediately shrink to the preset aperture to complete the film**, and at the moment of completion, the aperture will open again to its maximum aperture in preparation for the next shot.

Large, inconvenient to carry.

There are many buttons, and it takes time to get used to and learn.

It's expensive, it's much more expensive than the average camera, and it's distressing to bump it.

It's a waste of time, you need to spend a lot of time researching pre- and post-photography.

1: As the name suggests, the machine is the machine that puts you in, so that you can play and practice first, and when you practice almost, it will naturally give birth to a lot of dissatisfaction, at this time you will be on the set, you will want to buy a better lens, a better body, in short, according to the economic strength to toss it. At this time, the mission of the set (including the sleeve) is completed, and it should appear in the second-hand market. . .

2: Of course, the lens of the set can shoot a wide angle**, which is the most basic.

3: Buy second-hand it, this is a lesson learned after going through many detours, digital cameras depreciate too fast, the experience is that the product is the most cost-effective after half a year on the market, at this time there are often a large number of second-hand phones, in fact, they are still very new, most of the people who come out of this machine are fledgling novices like the landlord, a lot of shutter 5000 have not been, ** is also fair.

As for the risk, find someone who knows how to accompany you, the risk is basically zero, and businessmen also watch people put down dishes, so if you can't find it, you can prepare more classes online, at least pretend to be knowledgeable. Another way is to go to the photography forum to see if there is a player who comes out by himself, you can contact him directly, and under normal circumstances, you still believe it.

It is recommended to buy Nikon D3000, 3,000 yuan to get it. I can add some lenses in the future! It's very suitable for beginners! It has the purpose of spending a lot of money and basically enough.
