Why aren't the pixels of cameras used in professional photography competitions particularly high?

The biggest difference between high-end cameras and low-end cameras is the size of the photosensitive software. At present, it can be said that under the same conditions, the larger the film size, the better the imaging effect. For a simple example, the pictures in magazines are very fine, which can be regarded as high resolution. Outdoor advertising looks rough at close range, but it is as exquisite as magazines at a distance. Ok, then let's enlarge the magazine to the size of outdoor advertisement, and you will find it very blurred, while if the outdoor advertisement picture is reduced to the size of magazine, you will find it more exquisite than the magazine. Therefore, the bigger the negative, the bigger the photo can be, the more exquisite the reduction of the big picture, and the worse the enlargement of the small picture. This is a fact.

Generally, the pixels of a camera with a large base are not very high, because its imaging is accurate enough. A camera with a small base must increase the pixels, otherwise it can only take small photos, and it will be even more ugly without HD.

A camera, perhaps to take good photos, is a huge system, not a single goal such as resolution. The size of photosensitive element, lens, focusing system and high-sensitivity form mainly affects the quality of camera film. . . There are many detailed goals, such as the difference between professional cameras and civilian cameras. Just outside this goal, beyond this goal is comprehensive. It is not that a civilian camera is particularly top-notch and can beat a professional camera.

Nowadays, businesses are all hype concepts, fooling new people.

Pixels do not represent the clarity of imaging. For example,1cm 3 has 100 pixels on the desktop, and 1000 pixels.

But pixels do not represent the quality of imaging. The real quality lies in the size of the photosensitive element, just like the CPU of the computer, which is the center of the computer and everything else revolves around it. For photosensitive elements with the same size, the corresponding pixel can be 1000 pixel or1000 pixel, but the imaging is the same, because a photosensitive plate (photosensitive plate) carries the same amount of photons.

The desktop of our notebook is about 300W pixels. It's useless to have too many pixels. It's just a gimmick.

There are many aspects of imaging quality, and I mainly talk about pixels here.
