数码相机与胶卷相机的比较 Digital photography is the crystallization of the IT industry and the development of photography, digital photography technology and aesthetic elements are derived from traditional photography, so a good grasp of traditional film photography is helpful to use digital camera to shoot good photos. Digital photography, of course, is rooted in new digital technology and image processing techniques. Some basic photographic techniques (such as lighting, exposure and composition) are important, but there are still many problems that require digital photographers to draw attention to: 1. shutter delay How to do it: keep the camera still for a few seconds after pressing the shutter release button. For the traditional camera shutter release, this delay from the press the shutter button to be ignored. And for digital cameras, it wont work. Different types of digital cameras shutter delay is not the same, the price of digital cameras will react more slowly. Some digital cameras produce beeps or beeps after the photos are taken, while some do not have a sound, which makes it impossible to determine whether the camera has been taken. You might think that the traditional SLR reflector or shutter sound is a great advantage, but in fact, many professional photographers never like the sound of a reflector or shutter. 2. optical zoom and digital zoom Operating technique: do not use digital zoom. Only low-end digital camera digital zoom, but also has a high-end camera optical zoom and digital zoom, optical zoom mode and traditional zoom lens are similar by moving the lens element to change the focal length of the lens. Digital zoom is the only thing available for digital cameras. The principle is to use only part of the CCD element to capture the image, thus reducing the angle of view and creating a sense of distant objects. Show the image of the same size with a small part of the CCD, the image quality will be damaged, the final image of noise will increase, this noise is
