The imaging quality of a digital camera depends largely on the pixel level of the imaging chip. Chip called the CCD on the pole pixels, pixel number, the more the higher pixel level, the resolution of the image is, the higher the subject images will be fine, clear, distinct; On the contrary, the picture is more coarse. The higher the pixel level and the resolution, the higher the cameras level and price, the better the image quality will be. 2. What is digital zoom? A digital camera equipped with a fixed focal length lens can simulate optical zoom and form a zoom image, which is called digital zoom. The way it works is similar to how we zoom in on a piece of the image in a computer, and the difference is that the digital zoom is done directly on the CCD during the shoot. Digital zoom principle of the actual application in the late photo processing, precise, digital zoom is only a kind of cutting tool, because it can cut off part of the image - this section when using long focal length lens is out of sight, and store the selected only a particular local area. 3. What is optical zoom? For digital camera, the optical zoom will not change the size or resolution images, is used to describe the number of the picture also remains the same, that is zoom and digital zoom fundamental difference, reflected in the image, is the image quality will be different Why use a flash? When shooting, turn on the flash to make up for the light. 5. How to eliminate red eyes? Red-eye phenomenon in portrait photograph (especially close distance, the environment is dark) often happens. This is because the eyes of retinal reflex flash. If you dont want shoot out into the eyes of the person or animal in red eye, can use a digital camera red-eye removal pattern let flash fast blink once or several times, make the persons pupil after adaptation, and then to the main flash and shooting.
