It is obvious that half a frame is the progress of science and technology. Why do many people still support Quan Huafu?

Half-frame and Quan Huafu are not directly related to the progress of science and technology, nor are they good or bad.

It's just the result of diversified types of photographic equipment, each with its own needs.

From small to large, there are roughly:

Mobile phone camera, card machine, half frame, Quan Huafu (135 film), medium frame (120 film), large frame.

From left to right, it is getting earlier and earlier, and the picture quality is getting better and better.

From right to left, it is getting newer and more portable.

If you think that half a frame is a technological progress, then the mobile phone is more advanced?

The fuselage is thinner, the continuous shooting is better, the heat dissipation is better, and the pixel per inch per unit volume is larger. . .

It seems that everyone is talking about mobile phones.

On the other hand, if you insist on "foundation comes first" and firmly believe that image quality comes first, then you can choose a larger foundation and choose a large format.

The real situation is that there are many people who insist on large format and mobile phone photography, and there are also many fine products.

It is the best choice to use the equipment in your hand.

There must be a difference in image quality between outsole and outsole. Whether everyone can understand it is uncertain.

The importance of image quality in a work can be large or small, and image quality is definitely not the only standard that affects the quality of a work, or even an important standard.

Whether your works need such high quality to reflect, whether your thoughts support such high quality, and whether your audience needs such high quality to interpret your works are more important than the quality itself.

So for more people, it is nothing more than a compromise.

Choose the right equipment and stick to your own direction. I believe you can make some achievements.

Any problem, if only one of many factors is considered, will have the effect of "walking into a dead end"

Does the framework have anything to do with scientific and technological progress?

From this perspective, photography also has a history. The reason why the photosensitive elements in APSC format appeared in the digital age is because the yield of photosensitive elements in Quan Huafu was low in the early days of the rise of digital photosensitive elements, which led to high prices. In order to seize the market, there are photosensitive elements in APSC format, with 4/3 frames. That was almost twenty years ago.

It can be said that with the development of technology, the cost will drop, and the price in Quan Huafu will be lower and lower. If there is progress, it is not the frame, but the manufacturing technology of a whole set of photosensitive elements, especially the production efficiency. After all, the bigger the photosensitive element, the better. The larger the photosensitive element, the lower the magnification of the image and the richer the details. Just like the bigger the house, the more things can be put down, which is a fixed law.

The real scientific and technological progress is not the size of the picture, but the difference in quantity. Bigger than Quan Huafu are medium format digital cameras of various sizes. But so far, there is no digital camera with large-format photosensitive elements.

Then, with the improvement of the yield of photosensitive elements, is it possible to have a large format digital camera?

Digital photosensitive is different from film silver salt photosensitive. In the silver salt photosensitive technology, the unit photosensitive density of silver salt cannot be improved, so the only way to improve the image resolution is to increase the photosensitive area. This is also the reason for the emergence of medium format and large format in the silver salt era.

(mamia's warm memories of the past in the medium format camera)

In the digital photosensitive era, the resolution of the image can be improved by increasing the number of pixels under the condition of the same photosensitive area.

However, at the current level of science and technology, the larger the area of a single pixel, the higher the imaging quality in the case of low illumination and high sensitivity. That's why Quan Huafu Sony's A7S3 has only12 million pixels. Because in the case of constant unit area, the larger the area of a single pixel, the lower the noise and the lower the calorific value. Sony A7S3 is a camera, which needs to be optimized for high sensitivity and heat generation.

Therefore, the photosensitive area and the area of a single pixel are still restricted. The photosensitive area is constant, and the number of pixels is not as high as possible.

The real technological progress is the emergence of algorithmic photography. That is, computer simulation of optical imaging. In algorithmic photography, optical imaging is not so important, what matters is the calculation program. This is a qualitative change.

In fact, algorithmic photography in the primary sense has long appeared. As early as 1990s, Nikon appeared 3D matrix photometry, and a large number of computer intelligent image patterns were stored in the camera. This is the early algorithmic photography, but the calculation program involved in the exposure coefficient in this period, and now algorithmic photography has realized overtaking in corners and directly involved in imaging through the data stored in the computer. Through computer simulation imaging, take the desired photos.

This is why mobile platforms such as Huawei are so good at photography.

Technically speaking, the production of digital large format photosensitive elements is not difficult, and the price problem caused by the yield is still the constraint. From the imaging point of view, the imaging of medium format digital camera is completely sufficient.

In addition, there is now the translation technology of photosensitive elements. This technology can be applied to anti-shake and shooting high-resolution images. Through the subtle translation of the photosensitive element, the unit pixel area is actually increased in disguise without increasing the area of the photosensitive element. Nine pictures with adjacent photosensitive points on the left and right two-dimensional planes are taken and spliced into a high-resolution static image of Juck Zhang. From this technical point of view, the existence of large format does not make much sense.

Because the camera is a handheld device after all, people's physical strength is limited, and photography is a technology that needs stability, so the smaller the camera, the better. There was a big picture before, and there was nothing I could do about it. Now that science and technology have advanced, it is naturally a good thing to be able to do less.

So, there is the Sony A7C camera. This camera is actually quite innovative. Why do you say that?

(Compact interchangeable lens Quan Huafu digital camera. This is really a new thing that will only appear in 2020. )

At present, the form of digital SLR camera is inherited from film SLR camera, but for digital photography, the mirror optical system has lost its importance in the film age, and it can be completely solved by electronic system. The electronic system only needs to solve the problem of time delay. Now, the time delay has been basically shortened to the time that is imperceptible to the naked eye.

So the reflective pentaprism structure on the top of the warship becomes less important.

Before Sony A7C appeared, Quan Huafu's famous compact cameras were Leica Q series and Sony's Quan Huafu Black Card. But both cameras are cameras with non-replaceable lenses. The appearance of Sony A7C makes Quan Huafu compact interchangeable lens camera enter a more practical stage.

I believe that Sony A7C will not be the only compact full-frame camera, and then all major manufacturers should release compact full-frame cameras. This kind of camera is lighter and less aggressive, and it is not easy to attract the attention or conflict of the subject. It is a good equipment for street shooting and snapshot.

In the foreseeable future five years, mobile phone algorithm photography will be more powerful. Gradually erode the market share of cameras. What the camera can do is to be smaller, have better imaging quality and focusing performance, and develop video shooting performance at the same time. Perhaps one day, the computer will completely simulate the effect of optical photography, and on that day, the camera will become a work of art for minority players.

Yes, your photography and post-production must be terrible. In the same distance, Quan Huafu can accommodate a lot of content, and the shooting environment is sometimes narrow enough for Quan Huafu. If you don't understand these things, you can ask and prove that you are ignorant.

As a photographer, the standard of choosing photographic equipment depends on applicability and economic ability. No one will choose a camera because of support. There is no such thing as supporting half width or full width. At the same time, it doesn't exist. Only half a frame is scientific and technological progress. In fact, Quan Huafu is more scientific than half a frame.

Compared with the whole frame, half frame is not progress but compromise.

Quan Huafu's photosensitive area of 36 mm, 24mm and 24 mm is a compromise, which is suitable for the size of portable photographic equipment.

In history, there have been attempts to reduce the photosensitive size, and the tailoring of digital photoreceptors is only a stopgap measure to repeat the past.

Half-frame cameras existed as early as the 1960s, and Olympus Pen series cameras were one of them. Through one exposure 135 half of the film.

1972 Kodak also introduced 1 10 film and camera, which also triggered other camera manufacturers to follow suit. The film size of 1 10 is 17X 13mm, which is much smaller than the half width of 24 18.

However, these small-sized cameras are expedient measures and marginalized products.

The reasons for this are as follows:

1, and the photosensitive area is less than the full size, which affects imaging. We know that the format of 135 is actually a reduced product, because the products with 120 on it were once mainstream products, and with the progress of technology, 135 prevailed. However, when the photosensitive area is less than 135 frame, the imaging deterioration is obvious and inevitable.

2. 135 The camera itself can be made very small. Ricoh, Olympus, Condex and other manufacturers have many miniaturized 135 products with high quality.

3. Due to the limitation of manpower, the smaller the camera, the better. If it is too small, the grip and control will be affected.

After entering the digital age, you can add another reason.

Digitalization can further reduce the size of the camera, so the camera with smaller photosensitive area than the whole set does not have structural advantages.

With the micro-single replacing SLR as the mainstream, the next step will be marginalized. In fact, there is already this trend.

To sum up, the cut-off camera, that is, the half camera mentioned by the questioner, is not a symbol of progress at all, but an expedient measure of compromise. It is destined to be eliminated and marginalized in the future.

In the strictest sense, knowing Quan Huafu's size doesn't mean that they know photography. From their attitude of looking down on half a frame, we can know that they don't know what physical relationship is. In fact, when a photo is presented to people, it is these people who don't know whether it is Quan Huafu or half a frame. They are amateurs rather than picky.

Anyone familiar with film cameras knows that the concept of APS-C has existed in the field of photography for decades. In this respect, people who look down on half a frame can only be rare and strange.

In addition, some people in the photography circle don't understand the so-called equivalent coefficient and make irresponsible remarks. This kind of person is the most ridiculous.

Last month, I replaced the Canon 5d3 with a Fuji xs 10 half camera. It feels good, and the most important thing is that it is light and easy to shoot! Here is a half frame taken by Fuji!

The shrinking of the camera frame is really due to the progress of history.

Otherwise, if you go out to take pictures today, you will carry such a big guy out!

With the development of history, the frame of the camera is getting smaller and smaller, mainly for portability.

Then, the camera developed to the era of 6*7 frames, or even 6*4 frames, and began to be truly portable.

135mm format is actually a more convenient format due to the progress of post-printing technology.

In this era, a new era of civilian photography has really begun. SLR cameras, from professional to folk.

The progress of camera frame just shows the progress of technology. The appearance of half-frame and 3/4-frame is also in line with the original intention of being light and portable.

However, the half-frame SLR did not form a volume advantage with Quan Huafu Micro-Single.

Its advantage is limited to low price, especially in multi-lens configuration, the advantage of half frame is more obvious. Therefore, under the current technical conditions, half-frame and 3/4-frame should be the best choice for civil use. Its actual effect is not very different from that of a full-frame camera, but Quan Huafu is indispensable in the professional field. After all, the professional field earns money to eat.

Now the arrival of mobile phone photography has replaced the card machine used by ordinary people. Folk photography has gradually eliminated the existence of professional cameras!

Mobile phones can take good photos even for 3-year-olds through technologies such as multiple superposition, software calculation of depth of field, and AI automatic recognition! This is the real scientific and technological progress.

However, the pursuit of achievement is the common need of mankind. How to choose between extreme and portable has always been a contradiction. In fact, the dispute between Half Frame and Quan Huafu is a trade-off between price and technology. Once the camera breaks through the technical bottleneck of the frame, the camera frame will still develop towards miniaturization (except professionals). As a 40-year-old SLR player, I can't help asking you: Who says half a picture is the progress of science and technology? Japanese from Canon and Nikon camera manufacturers in Japan said it! Who later said that M3/4 is the future? Rule out all other camera techniques? Panasonic, these Japanese said it! As a result, M3/4 is now on the verge of being eliminated! If the half frame of "Ming Ming" you say is scientific and technological progress, then you have the right to continue asking questions. If not, please eat the word "Ming Ming" and ask questions again if you have no discernment and blindly worship Japanese businessmen's commodity advertisements.

Every scientific and technological progress may not be fully supported. The appearance of the car, some people think that it is not as covered as the carriage; Photography was introduced into China, which was regarded as western witchcraft and was banned for decades. Photography has entered the digital age for more than 20 years, but some people still think that digital is not as good as film. In digital photography, many people have realized that half-frame can fully meet the needs of photography, but the phrase "the bottom is too big, crushing people" has still become the spiritual pillar of Quan Huafu.

We can't completely assume that Quan Huafu is the best, because there is a bigger medium frame on Quan Huafu; We can't say half a frame can't be used. Practice has proved that half-frame can fully meet the needs of high-quality photography, and at the same time, it has reached the best balance point in production cost, sales price and practicality.

Theoretically, the larger the light receiving area of the photosensitive element, the better the photosensitive performance, the better the imaging quality and the better the high-sensitivity performance. However, we should not ignore the development of image sensor technology. In addition to the continuous improvement of pixels, various noise control technologies and high-sensitivity technologies have also reached a considerable height. Many half-frame image sensors can completely avoid noise at the sensitivity of ISO3200, and such high sensitivity performance can cope with most low-light shooting. Today's half frame not only surpasses yesterday's Quan Huafu in terms of pixels, but also is incomparable to Quan Huafu in terms of image quality and high sense.

At the same time, there is also anti-shake technology of the fuselage. With this technology, we don't have to rely entirely on high sensitivity in low light environment, and we can take satisfactory photos with low sensitivity.

For the choice of frame size, there is no need to consider it technically today. What you have to consider is whether you really know the camera and how much money you have in your pocket. Not to mention arguing about the size of the framework. In the early days of film photography, all the frames were very large, but the development of frames became smaller and smaller. Finally, the smallest frame 135 became the mainstream of photography. If it weren't for the emergence of digital photography, today's film photography should be the world of APS frames. The development of photography technology is that the camera is getting smaller and smaller, and it is more and more convenient to use.

There are three main reasons why so many people support Quan Huafu today: the substantial increase in income level (the key reason); Excessive pursuit of image quality; The third reason is that users themselves can't tell.
