Introduction to exposure modes of digital cameras

Because the types and grades of cameras are different, the exposure modes set by the cameras are also different. First, check your camera to see what exposure modes it has. The following is an introduction to the exposure modes of digital cameras that I have carefully compiled for you. I hope you like it.

Introduction to the six exposure modes of digital cameras

(1) Automatic mode (AUTO): This is the simplest exposure mode for general shooting purposes, also known as "fool". , the camera will automatically select the shutter and aperture according to the brightness of the subject. When the light is weak, it can turn on the flash automatically, allowing you to take pictures freely. You only need to concentrate on framing and pressing the shutter. Probably set up for beginners.

(2) Multiple changing procedures:

(1) Portrait mode: Use this mode to shoot portraits. It can create a blurred background to highlight the subject of the character. (It is recommended to use the telephoto end of the lens)

(2) Landscape mode: Use this mode to shoot distant scenery. The camera will automatically adjust a smaller aperture so that the entire scenery can be in clear focus: < /p>

(3) Close-up mode: Use this mode to take close-up photos, such as flowers or insects, and the photos will show an artistic blurred background.

(4) Sports continuous shooting mode: Use this mode to take photos of sports. It will use a high-speed shutter to freeze the dynamics of fast-moving subjects and create wonderful dynamic photos. This mode also provides continuous shooting.

(5) Night scene mode: Use this mode to shoot subjects with dusk or night as the background. This mode will capture all the light in the scene, including the foreground subject illuminated by flash, and the background. Eliminating the flash also allows you to capture natural-looking night scenes or twilight scenes.

(3) Automatic multi-program (P): In this mode, the camera will automatically control the shutter and aperture. But you can also make some settings. Such as flexible program and exposure compensation.

(4) Shutter Priority Auto (S): You set the required shutter speed, and the camera will choose the correct aperture. You can freeze the action of a moving subject at high speed, or use a slower The shutter speed makes the subject hazy.

(5) Aperture priority automatic (A): You set the aperture you need, and the camera will choose the correct shutter speed by itself, so you can use the aperture size to adjust what you need. range of depth of field, or choose to blur the foreground or background.

(6) Manual exposure mode (M): The shutter and aperture are set manually, which is suitable for use when other exposure modes are difficult to obtain the desired effect. This mode can also be used for long periods of time. Exposure (some cameras may not set this). Don’t be superstitious about DC’s automatic exposure mode

First of all, another biggest difference from traditional cameras is that DC has a white balance. This is somewhat similar to the color temperature in traditional photography. It is precisely because beginners do not pay attention to the white balance that they produce color casts. DC generally provides four modes: automatic, indoor, outdoor, and manual. Beginners trust AUTO, but often the pictures taken are biased to a certain color. This can be seen as long as we pay careful attention to the LCD viewfinder window. When we have just photographed a certain object, the object usually emphasizes a certain color. If it is blue, then the DC white balance will automatically tend to be blue. When shooting other objects, the color will naturally be biased. Although this will be reflected in the LCD, beginners generally do not notice it. At the same time, some modes are not perfect. For example, SONY's DC has "blue syndrome" in indoor mode, so we still use manual white balance as much as possible. Moreover, you should also pay close attention to the color changes of the LCD. Once you find that the white is not white, you have to re-take the light of the actual white object and correct the white balance. In addition, some digital cameras also have an automatic bracketing white balance function to record accurate color information.

Secondly, the control of aperture and shutter. It is recommended that if you have a manual camera, you should also use the manual mode, because the pictures taken in the automatic mode are usually dim, especially in the window, and there is a lot of noise. Because when shooting indoors, DC will generally automatically increase the ISO value. For example, SONYDSC-F505V generally reaches about 282 indoors, and the sensitivity is inversely proportional to the image quality. That is, the higher the equivalent sensitivity selected, the worse the image quality. . This is similar to the characteristics of traditional photosensitive materials, but this characteristic is more obvious on digital cameras. Therefore, when shooting with a digital camera, if you want to obtain good image quality, you should choose the lowest equivalent sensitivity as much as possible, or directly fix it at the minimum value.
