How does Canon 850D shoot the moon?

First set the correct aperture. You can't shoot the moon with the default maximum aperture of many cameras. Generally, an aperture of F5, 6 or smaller should be used. Then use spot metering to measure the brightness of the moon. In this way, the correct exposure coefficient can be obtained as much as possible. Then adjust the EV value. When shooting the moon, you usually need to subtract EV, which should be 1 or 2. The exact number depends on your shooting. Shoot according to different aperture and EV values, and adjust according to the results before shooting. These are easy to realize in DC, which greatly improves the success rate of shooting. Shutter speed should generally be set to1125s or faster. In addition to preventing overexposure, there is another important reason for using high-speed shutter, that is, the moon, as a celestial body, is constantly moving. If the shutter speed is too slow, it is easy to paste. Finally, the choice of ISO sensitivity and zoom. When shooting the moon, we usually choose the lowest sensitivity, either ISO50 or ISO 100. Too high ISO will not only cause overexposure, but also make the picture rough.
