What are the tips for purchasing a digital camera
4hw.com.cn: for many junior photography enthusiasts, a digital camera can meet their daily photography hobbies, but there are many choices for the digital camera sold, no matter the brand or model. What are the skills for purchasing digital cameras? Let's have a look.
1. Resolution of CCD
Generally speaking, the higher the resolution of CCD, the better the quality of camera imaging, but the higher the price is, how to make the higher the resolution of camera, and the price is not too high? Some intelligent manufacturers use the combination of the characteristics and software of digital cameras to improve the resolution and improve the imaging quality. One of the most famous software is photogenie, which is a special artificial intelligence technology, to avoid the phenomenon of high contrast tone, but angle and pixelation of images. The image resolution and hardware of this technology are used to achieve the image resolution and The effect of image resolution realized by hardware is similar. This kind of digital camera is cheaper by comparison.
2. Camera size and portability
The smaller the camera, the more integrated it is, and the more convenient it is to carry it. So when you buy it, you should compare the sizes of several digital cameras.
3. Zoom
The larger the zoom range is, the camera has wide-angle and telescope functions, and the zoom is also a direct proportion of the price of the digital camera, so there is a combination of Optics and digital zoom to improve the zoom function of the camera.
4. Energy saving of camera
Most of the digital cameras use 4 batteries and 5 batteries, but generally only 15 of them can be imaged without power (turn on the LCD or use the LCD to see the results), and even less than 10 of them, so some manufacturers have produced rechargeable batteries or power supply to provide the working efficiency of the camera, which brings inconvenience to the use of the camera. Some cameras, such as Epson, have several types of daylighting LCD screens, which reduce their power consumption to a very low level.
5. White balance (human eye function)
In short, the human eye will adjust the color sensitivity according to the different climate or light conditions, so that the white object will always be white. The white balance correction function is to make the camera have the same function as the human eye, and automatically adjust the internal color balance by calculating different lights. In order to achieve the effect of true reproduction of white under all conditions, however, it is still necessary to carry out artificial white balance correction for color reproduction in light environment.
6. Close range
The closer the close shot is, the more clearly you can see the tiny text or group patterns.
7. Exposure compensation
A digital camera with exposure compensation can change the darkness of a picture.
8. Compatibility
Some cameras only support IBM-PC, so if you use Mac, pay attention. And if you want to watch and shoot on TV, you have to see whether the digital camera is and supports TV output.
