The difference between card machine and ccd

Ccd is a card machine. What we usually call ccd is actually a card machine, but it generally refers to most old card machines.

Ccd is a photosensitive element, which refers to a charge-coupled device. The target is a cmoc sensor, and the card machine is a camera, generally using a ccd sensor. The target is mainly SLR, micro-single camera and so on. Card machine is a common name for small photosensitive elements and portable cameras with non-replaceable lenses. The function of CCD is like film, but it converts image pixels into digital signals. There are many neatly arranged capacitors on CCD, which can sense light and convert images into digital signals.

CCD is the name of a photosensitive element, which is famous for its bright colors and high saturation contrast. Cameras with CCD as photosensitive elements are often used as digital film machines, which can be said to have been eliminated. Now the newly released cameras widely use CMOS photosensitive elements.

Shooting skill

1, macro photography

Compared with ordinary consumer-grade DC, the macro function of card machine is weakened, especially for those models with periscope lens structure, and the macro effect is undoubtedly discounted, but this cannot be the reason why we can't take good photos. Pay attention to the exposure and shooting angle before taking macro photography with the card machine. If possible, use optical zoom slightly to reduce the distortion at the wide-angle end and try to find a place to fix the camera. At the same time, the camera should be set to a forced non-flashing state to avoid overexposure of the subject.

2. Landscape photography

Choose the scenery mode of the card machine and shoot with the wide-angle end of the camera. If zoom is used, the significance of scenery photography will be lost. In shooting, it is especially necessary to pay attention to the incident direction of light and try to avoid shooting at a large backlight angle. However, in order to avoid the halo phenomenon and prevent sunlight from refracting into the lens, it is even necessary to manually adjust the white balance effect in some special periods, such as cloudy days, sunrises, sunsets and other environments, which must be flexibly adjusted by the photographer himself.
