Why do landscape masters love “slow door”? Feel different scenery, you can also use

When it comes to slow gate, I believe everyone is familiar with it. As the name implies, it is to extend the shutter to obtain a long exposure. The camera is no longer to capture a short moment, but to record the changes in the picture over a period of time. This is the charm of slow gate. < / P > < p > scenery photography tends to pay more attention to image quality, so the ISO will be reduced to the minimum to ensure that the shutter will also be slower to obtain adequate exposure, which is why many landscape photographers often use tripod. < / P > < p > sometimes, in order to get some special dynamic effects, such as the common Flowing Clouds and flowing water, the dimmer is installed in front of the lens to reduce the shutter speed, or the stack method is used. The stack can show the slow door effect without the dimmer during shooting, which reduces the burden of purchasing dimmer for many photographers, of course It increases the workload of the later stage, and there are gains and losses. < / P > < p > it is a big test to shoot high-definition and clear night scenes. If you want to take a clear picture of the night scene, you will generally increase the shutter speed, enlarge the aperture, and increase the ISO. Doing so may make the depth of field of the photo shallower, thus blurring the part outside the depth of field of the photo. Moreover, when the ISO is higher, the noise will be increased and the photo quality will be reduced. At this time, you can try to use a long exposure, plus a small aperture and set a lower ISO, the resulting photos are not only clear, but also bright and colorful. < p > < p > using slow gate to photograph the sky, orbit and light drawing of city stars has produced many effects that are hard to be detected by the naked eye, which is beyond the original visual limit of people.
