Is the card camera a product of high and low?

Different requirements and different positioning also contribute to different technological content and materials, and the card machine was originally positioned to be portable, sacrificing some image quality and shooting functions. With the improvement of the image quality of the mobile phone,Portability has been threatened,And the quick social function that the mobile phone can be directly released to the circle of friends after shooting,It squeezes the space of the card machine,Although in general, the picture quality of the card machine is still better than that of the mobile phone,But this gap is completely eliminated for users who are just for the circle of friends,Because it will be miniature when posted to the circle of friends。

The general population,The card machine has lost the advantage of picture quality,If you don't want to be eliminated,Only add the function of supporting SIM card to improve portability,But no matter what, do you let the card machine support WeChat QQ? And** went up but minus points, add a few hundred dollars to buy a card machine my mobile phone is not more convenient, born for information exchange, with this money to invest in two equipment I will not buy a better mobile phone? No matter how portable it is, going out with two devices is no more portable than carrying one.

Picture quality? If you want to have a certain image quality requirement, you don't care about portability and don't consider sending it to Moments, because you can't see the difference in image quality on your mobile phone, if you have certain portability requirements, then you must choose mirrorless or mirrorless, because they can all shoot in RAW format.

Wrong, the old card is not as good as the mobile phone picture quality.

Imaging results vary from person to person.

Generally speaking, the larger the size of the image sensor, CCD or COMS, the higher the image quality.

For example, Panasonic LX5 [1-inch CCD], Canon S95 [1-inch CCD] and other cameras have better image quality than ordinary 1-inch CCD cameras. The reason for this is because the larger the sensor, the more detail it holds. If the sensor is the same size, the lower the pixels, the smaller the density, and the higher the image quality.

Some cameras use COMS, some use Exmor Coms, and some use Super CCD, etc.

COMS is characterized by faster processing, less noise, and so on. Each has its own characteristics, depending on the need. But what is certain is that the bigger the size, the better.

The image processor of the camera is different from each manufacturer, and the effect characteristics are different.

For example, it is often said that Canon's color is reddish, Panasonic's greenish color is suitable for landscapes, and Sony's yellowish color is not suitable for portraits.

For camera lenses, it's not always the case that the aperture is bigger. The larger the aperture, the higher the cost of the lens,** the higher. The effect on ** is only to open the wide aperture background blur, but it is not obvious on the card machine.

When the light is low, a wide aperture increases the shutter speed, but in fact, the depth of field becomes shallower, and the image quality decreases.

There are not too many requirements for choosing a lens, and the so-called wide angle is only a wider field of view, but if the lens is distorted, it will affect the image quality.

There's a lot more, and LZ is testing me. Anyway, no matter what the configuration is, there is no absolute good or bad, and the key to choosing a camera is appropriate. If you need to buy a machine, please consult again.

The larger the CCD area, the better, and the higher the lens resolution, the better.

Lens, aperture, image sensor.

The main thing to look at is the aperture, the bigger the better, and whether the angle is wide, the pixel should not be too high, it is best not to exceed 1000W, otherwise the photo is easy to appear noise.

I recommend one: the Canon IXUS300 HS, except for the LCD screen with a lower pixel, everything else is fine.

1. All cameras with single-lens reflective viewfinders are called SLRs. In layman's terms, it is the ** of the viewfinder window you see, which is directly retracted from the lens and reflected to the viewfinder by the Wuling lens.

Today's digital cameras rely on CCD COMS to compare the most sensitive sensors, the outer than the pixels, and the inner than the gray scale, sensitivity, and color reproduction realism of these sensors. This is the reason why the 8-million-pixel SLR sensor (the same size as the negative) is more imaging than the 18-million-pixel card machine***. Of course, it also has a certain relationship with the quality of the lens.

Compared with ordinary card machines, SLR is out of the film***. In view of the fact that the landlord can't stand the professional vocabulary, I won't analyze the reasons here.

SLR: The light rays are divided into two groups in the machine:

1 light reflector and viewfinder eye.

2. Light sensor.

Card: Light Sensor Screen Eye.

Because the SLR camera enters with line 1, you can see the light faster than with a card, which is one of the advantages of a DSLR.

This question is too popular.

In a DSLR camera, the light enters the camera from the lens, and there is a 45° reflector in front of the image sensor, which folds the light upwards and then passes through a five-sided lens at the upper part of the fuselage (the high-end uses a one-sided five-edged one, and the low-end uses a combined five-sided) to refract the light into the viewfinder. When taking a photo, the reflector is raised, and the light shines directly onto the photoreceptor behind it.

The superiority of the performance is the largest, because the SLR is full of materials, and the image sensor is dozens of times that of DC, so it is ...... in image qualityIt has great advantages in color restoration, performance (that is, white balance, this section can be really tiring without technical terms), stability in low light (ISO), and large difference between light and dark (large light ratio).

The superiority of shooting, because the shutter is different, only need to lift the reflector (DC is the curtain, close first and then open), so the shutter is fast and the delay is small.

The superiority of framing, what you see and what you shoot. Carefully compare the ** of DC shooting and the difference we see on the screen, take a ruler and try it, the upper edge of the screen is 90, and it is 100 when you find out, which is very uncomfortable for our composition. The SLR is 100% imaging because it is a full light refraction (the low-end one seems to be about 97).

The macro function of the card machine is diluted compared with ordinary consumer-grade DC, especially those models with a periscope lens structure, and the macro effect is undoubtedly discounted, but this does not become a reason why we can't shoot well.

If possible, you should use optical zoom to reduce the distortion at the wide-angle end, and try to find a place to fix the camera, such as a tripod, desktop, etc., and set the camera to force no flash to avoid excessive subject. Many readers have encountered such a problem: the card machine is not easy to stabilize, and the ** shot is easy to be empty.

For card-based DCs, auto mode is usually the best mode for shooting. Based on the fact that the current card machines are becoming more and more mini, the manual function is relatively weak, so the user must first train how to shoot clearly, and then gradually improve the shooting level. When it comes to image stabilization, not every manufacturer's card player has an image stabilization system built into the lens like the Panasonic FX series.

The manufacturing technology of the sensor is getting more and more advanced, and the algorithm is becoming more and more optimized, resulting in the smaller and smaller surface connection of a single image sensor unit, but the image quality is still getting better and better, at least not worse and worse as you said.
