Parameter value of automatic mode 2000E: 1, and the gain shall be kept at-3 as far as possible; 2. The shutter speed should be 1/50 seconds; 3. The aperture should be1.6 as far as possible; 4. When the light is different, it will automatically adjust the aperture at the beginning, which is very sensitive [the machine will always work at the shutter speed of 1/50 seconds, and the gain will always remain at-3]; 5. When the light does not meet the normal requirements, the gain value will increase, the aperture will always be kept at the maximum 1.6, and the shutter will always be used at 1/50 seconds; 6. When the light exceeds the normal requirements, the aperture value will decrease from 1.6, the gain value will remain at -3, and the shutter will be used for 1/50 seconds; 7. If the light intensity keeps increasing and the aperture value reaches 6.8, you will be prompted to increase the nd mirror. After changing the ND mirror, the machine will work at the shutter speed of -3 gain 1/50, and automatically adjust the aperture to control the correct exposure of the machine. The increase of light intensity will further promote the neodymium mirror ...; 8. If the cameraman fails to follow the prompt requirements after prompting the ND mirror, the 2000E will use the automatic shutter speed to complete the correct exposure, which is very sensitive, and the highest shutter speed can reach110000; In short, 2000E will use the shutter speed as low as possible; Negative gain; Maximum aperture, a series of settings optimized for users. If your hands can meet the above requirements, and you can sensitively find and handle this series of changes, then you will be an amazing senior photographer.
