How to improve the photography technology of digital camera

Digital cameras use five secret digital cameras and five secret digital technologies to promote the arrival of the era of civilian photography. As long as ordinary people have a digital camera, they can shoot satisfactory works without complicated training. Of course, good works still need some technology to ensure, but digital photography is different from traditional photography. These five secrets of digital photography are the summary of the author's photography practice, hoping to help beginners improve their photography level quickly. 1, should have a certain computer foundation, can use computers. Understand the use of basic software and hardware, and be able to use an image processing software. Know what digital technology, digital image, file format, file size, resolution and other concepts are. Of course, proper post-processing is also based on computer operation. The use of computers is the basis and the biggest difference between digital photography and traditional photography. If you don't have this foundation, go back to play movies early and don't touch the numbers. For example, the quality of digital photos is directly proportional to the pixel value. The larger the pixel value, the better the image quality, but the amount of files will also increase, and the storage space of digital cameras is limited. The increase of pixel value will affect the shutter lag and processing speed of digital cameras. Therefore, we should make a reasonable choice according to our needs. Generally, 5-inch photos are enlarged and output, and 2 million pixels are enough to meet the demand. But if it is only used for the display of ordinary computers, the requirements are low. The resolution is 72 dpi, and the pixel size 1024X768 and1100,000 pixels is enough. For printing, it depends on the size of the pixel value. 2. Read the instruction and guide of digital camera carefully, you should know your digital camera like the back of your hand. There are many kinds of digital cameras with complex functions, and they are updated quickly, and different models are very different. When buying a camera, you must read the instructions carefully and be familiar with the menus and functions of digital cameras. When you don't know anything in the future, you can look it up at any time, and there will often be new gains. This is a shortcut with twice the effort. Unlike traditional cameras, different models of machines can be used when picked up. Many players don't like to read complicated product manuals. This bad habit should be eliminated in the digital age. 3. Make sure that the exposure of the digital camera is correct. Accurate exposure is the biggest difficulty in photography, but it is much simpler in the era of digital photography, because digital cameras have automatic metering function and LCD screens that display images randomly. Generally speaking, automatic metering is enough. If the picture of automatic metering is too bright or too dark on the LCD screen, you should use exposure compensation or manually adjust the camera shooting value. If there are large dark areas or bright areas during shooting, it may be overexposed or underexposed automatically. At this time, you should use spot metering to judge exposure value manually. Don't believe in automation, the human brain is always higher than computers and machines. For underexposed photos, don't always expect later computer processing and correction. For the average computer user's operating level, it will never be better than the initial successful shooting. 4. Make good use of the flash of digital camera. Because the maximum aperture of ordinary portable digital cameras is not too large, it is often necessary to use a flash to ensure adequate exposure. Attention must be paid to the distance between the flash and the main body to obtain the correct flash effect. And in the case of using flash, we must pay attention to the relationship between foreground and background. Don't use flash when you are close to people, it will cause bad white spots on your face. In the case of backlight, using a flash to fill the light will take an extremely beautiful picture.
