Slow shutter shooting: capture fleeting colors and movements.

For beginners who just started photography, what is a slow shutter is a difficult problem. In photography, there are more technical terms waiting for us to study. Now let's see what a slow shutter is!

In fact, speed and slowness are relative, and the speed and slowness of lenses with different focal lengths are also different, but basically, the number of shutter speeds is less than the number of lens focal lengths (that is, lower than the safety shutter), so the image is prone to jitter (commonly known as hand shake), which is considered as a slow shutter.

For 200mm lens, the safety shutter is 1/200s. Compared with a 50mm lens, the required safety shutter is only 1/50s, which seems to be much faster. But if the former is lower than 1/200s, it is necessary to connect a tripod to avoid hand shock, that is, 65438.

Capture the alternation of cold, warm and bright colors in the sky

This is the morning when the sun has just risen. It took115 seconds and f 1 1 to capture the alternation of cold and warm colors in the sky.

What we usually call slow shutter is only for long exposure mode, which is about 1/20 seconds to 20 seconds. Long exposure requires a good aperture and a tripod. Because of the use of a fine aperture, the exposure time naturally increases, and more light can be absorbed, and some colors that we can't usually detect with the naked eye can also be recorded. Because of the tripod, the stability of the camera is greatly increased, and there will be no image jitter during long exposure.

With the use of fine aperture and long exposure, the depth of field is wide enough and the tone is thick enough, which is most suitable for shooting dusk tones, urban night scenes and other scenery, especially the capture of magical moments in the morning, and plays an indispensable role.

The inverted image of Nanwan Lake is as clear as a mirror.

It was shot at about 9: 00 a.m. and took 20 seconds. The reflection of Nanwan Lake was as clear as a mirror, and the rich colors of various lights made the picture colorful and layered.

In terms of taking landscape photos, completely static scenery is not as good as dynamic scenery, so how to take dynamic scenery? The answer is that only a slow shutter can capture that kind of movement, such as the stars in the sky, the light flow of cars on the earth, and the misty water; The first two are long exposures that require tens of seconds to several hours, while the latter can only be shot with a slow shutter below110 seconds.

Fast flowing water

Capture the smooth dynamics of water flow.

This waterfall was taken in the afternoon, and it took110second f22. In such a bright situation, the slowest shutter should be1100 seconds. At this time, two dimming filters are used to reduce the amount of light, so that a slow shutter can be used to capture the silky dynamics of water flow.
