Several factors affecting the imaging quality of digital cameras

1, pixel. A high-pixel camera can take higher-resolution photos, and then you can cut out what you want. Therefore, a high-pixel camera can make the photographer less constrained by composition, but it is not directly related to the imaging quality.

2. Imager size. The size of the imager directly affects the sensitivity of the camera to light. Contemporary products, the larger the imager, the richer the imaging details, and the better the background blur effect.

3, the lens. Different lenses have different effects on light transmission, so the price of lenses varies greatly.

4.light. Different light, such as photometry, backlight and backlight, have great influence on the imaging effect. In order to prevent overexposure or underexposure, the application of shadows is also very important to the aesthetic feeling of the picture.

5. aperture. The aperture size affects the amount of light entering and the depth of field, that is, the degree of background blur.

6. The ISO value of the International Organization for Standardization is related to the sensitivity to light. The higher the ISO, the brighter the photo, but the higher it is, the easier it is to have noise. If it is too low, the picture will be too dark to lose details.

5, focal length. That is to say, zoom, different focal lengths affect the focus position of the shooting picture, and long focal lengths will bring better blurred background.

7. Anti-shake. The direct result of jitter is blurred picture. Although most cameras now have anti-shake function, they can only be improved to a certain extent. In the final analysis, the photographer's hand stability is still needed.
