Timing of using medium gray mirror

In most photographic occasions, strong light is often needed to supplement the light, which can not only reduce the influence of hand jitter, but also be a necessary condition for capturing instantaneous things. But sometimes when shooting a dynamic theme, we hope to have a dynamic effect in the photo to express the actual situation at that time. At this time, a slow shutter must be used, and overexposure is often the inevitable result. The medium gray mirror is designed to meet such shooting needs. The following three commonly used mirror reduction environments and shooting sites are for reference only. For consumer digital cameras shooting under strong light, there are many restrictions on the range of aperture and shutter due to market considerations. As for the shutter, the shortest shutter is mostly in11000s ~1/2000s, and the small aperture is about F 1 1. If the shutter speed is not enough, overexposure may occur under strong light, especially at the seaside in summer. When shooting a foggy moving picture, the faster shutter can condense the motion, while the slower shutter can record the trajectory of the motion. When shooting running water during the day, if you want to shoot a picture with dynamic effect, you can choose landscape mode in the scene mode. Using a digital camera with manual function (M-mode), it is more likely to use aperture priority (AV or A) to set a small aperture for shooting, and the shutter speed will slow down. If the user directly sets the shutter priority (T or TV) or full manual mode (M), it is necessary to pay attention to whether the aperture reaches the minimum limit when setting the slow shutter. If the minimum aperture limit is exceeded, the captured image will be overexposed.

In fact, it is often found that even if the minimum aperture is set, it is quite difficult to shoot beautiful running water from the perspective of daytime brightness. At this time, we can use the reducing mirror to reduce the light, effectively reduce the shutter speed, and it will be easier to shoot dynamic images. It is especially suggested that when shooting such subjects, you can shoot with a tripod or put the mirror in a stable place to avoid the static objects in the picture from being blurred by vibration. The application of night shooting is believed to be a big challenge of photography technology. Digital cameras can preview the shooting results in real time. For novices, it is much more convenient for night shooting in cities with high failure rate, in addition to shooting for a few minutes or even hours in orbit. Even so, when using consumer digital cameras to photograph the flow direction of car tracks, it is often found that only one car track can be photographed, but not the whole line track.

The light damage in cities is quite serious. When using a consumer digital camera, because its small aperture can not effectively reduce the exposure, the shutter speed will be limited, so it can not be exposed for a long time, otherwise it will be overexposed. If we use a small aperture with a variable diameter mirror, it will not be difficult to shoot beautiful rails.

The shooting method is to fix the camera on a tripod or a stable place, set the scene mode to night scene mode, or set the aperture priority (AV)/ manual mode (M) to small aperture for overall composition. After the composition is completed, add a medium gray mirror. At this time, users using M mode need to slow down the shutter until the exposure compensation value becomes "0".

Using the timed self-timer function to shoot can avoid image jitter caused by the action of pressing the shutter by hand. In addition, you can use exposure compensation to take more photos of different exposure value. I believe you can put your beautiful night scene into the photo album.
