Manual exposure mode means that the photographer needs to set the aperture coefficient manually when shooting.

Manual exposure mode means that the photographer needs to set the aperture coefficient and white balance manually when shooting.

White balance literally means white balance. White balance is an index to describe the white accuracy of the mixed red, green and blue primary colors in the display.

White balance is a very important concept in the field of TV camera shooting, through which a series of problems such as color restoration and tone processing can be solved. White balance is produced with the true color reproduction of electronic images, and it was applied earlier in professional photography. Household electronic products (home video cameras, digital cameras) are also widely used. However, the development of technology makes white balance adjustment easier and easier, but many users still don't understand the working principle of white balance, and there are many misunderstandings in understanding.

It is to realize that the camera image can accurately reflect the color condition of the subject, with manual white balance and automatic white balance. Many people will encounter such problems when shooting with digital video cameras: the images taken in fluorescent lamp rooms will be green, the scenery taken in indoor tungsten lamp will be yellow, and the photos taken in sunlight shadow will be blue inexplicably. The reason lies in the setting of white balance.

There are three aspects of camera exposure control settings: shutter control. Use the length of the shutter opening time to control the exposure. Aperture control controls exposure by changing the amount of light passing through the lens. ISO sensitivity control. Exposure is controlled by changing the sensitivity of photosensitive elements to light.
