In the process of photography, the aperture value and shutter speed of the camera are very important. The aperture value is mainly used to control the size of the light passing through the hole, while the shutter speed is used to control the time when the light is projected onto the film. Only when both of them are set properly, can the most satisfactory exposure effect be achieved. As for the control and selection of shutter speed, to put it plainly, the shutter is equivalent to a curtain in front of the film. According to the opening size of the curtain, the intensity of the light projected on the film is determined. To control the size with time is the so-called shutter speed. Annie Griffiths Belt, a famous photographer of National Geographic, collected the works of 10 photographers from National Geographic magazine and analyzed their ideas when taking photos for you. This time she will teach us how to set the appropriate shutter speed to stop the time. Let's learn together.
Annie Griffiths Belt grew up in Minnesota and graduated from the University of Minnesota with a bachelor's degree in photography. I started my photography career when I was in school, working in the Minnesota Daily. After graduating in 1976, Belt joined Worthington Global Daily. He has won awards from the National Photography Association, the Associated Press, the International Women's Organization and the White House Photographers Society. Her works have also been exhibited in New York, Moscow, Tokyo and other countries. She also holds regular lectures in some schools. She was the first female photographer in National Geographic magazine.
The Colosseum, like many iconic sites, has been photographed thousands of times. But in this amazing photograph, Heather Perry exposed the historical monument for a long time and presented a picture we had never seen before.
Photo Tip: Each photo actually takes a certain exposure time. Photos can be images that record a fraction of a second or several hours. Many people never realized that they could use time as a creative tool in photography. Keep in mind that the shutter speed can be adjusted to grow exposures or instantaneous exposures.：

In this simple photograph taken by Kazinger, the slow exposure camera records the swimming movements of the newly hatched turtle, but the instantaneous exposure will fix a series of movements of the turtle. This image impressed us deeply with the swimming of this little turtle.
Photo Tip: When the shutter is pressed, many photographers do not realize that they can create different images by changing the speed of the camera shutter. A slow exposure can record the process of motion, and the shutter captures a moment of blurred motion.：

Exposure time allows me to record what we can't see with our naked eyes. In this beautiful photograph taken by Eva Tromatac and John Eastcott, we can see the wild horses in a new way, with their blurred feet, tails and manes forming a real running scene.
Shooting Tip: The method of selecting the exposure speed for a long time and tracking the action occurring is called lens-shifting shooting. One of the pleasures of moving lens photography is that the photographer never knows what the final image of the photograph is. In a sense, photography sometimes shows things that we can't see with our naked eyes.：

This flexible photograph taken by Bruce Dell makes us feel that we are moving on the train beside him. The blurred scenery near is dizzying, but the distant scenery is exceptionally clear.
Photo Tip: When shooting from a moving object elsewhere, try slow exposure with a wide-angle lens. Close-range scenes tend to fade away faster than distant backgrounds, and the images taken will certainly make the viewer feel dizzy.：

Although photographers often fail to take good pictures in poor light conditions, slow exposure can sometimes produce a surprising picture, which is distinguished by the virtual action in the picture. A pair of hummingbirds photographed by Joe Petersburg is one of the successful examples of this unexpected effect.
Shooting tips: Even for wildlife, low brightness and long exposure can produce unexpected and unusual pictures. Don't complain about the bad light. Use it to take innovative pictures. Wonderful things will happen!：

The use of long exposure to the rapids of the river presents a fantastic canvas-like picture. In this picture, we see the running water swirling around a red maple leaf. By using slow exposure to blur the river, photographer Mike Yamashita sketches a leaf with clear lines in an abstract water.
Photo Tip: It doesn't take long exposure time to blur the jet water. Sometimes portable cameras can capture this effect. But bring a tripod so that you can try various lengths of exposure and see which effect you like best.：

It was the feeling of this movement that made this picture of the leopard fighting so successful. Some parts of the cat's body, such as its claws and ears, are very clear. But the blurred limbs are deeply attracted to us and suggest that powerful muscles are working hard to propel the animal. Photographer Richard Toit chose a perfect exposure speed to show the action.
Photo Tip: Although we all try to shoot wildlife with a fast exposure speed, slowing down the exposure speed may present a more attractive picture. The goal of photography is not always to get an unusually clear picture.：

In an abstract color whirlpool, this clear trunk keeps the seasonal image from spinning out of control. Imagine how many photographs have taken autumn colors, but Conrad Worth has shown us a new perspective.
Photo Tip: Remember, photographers can also move. You can rotate, run, and sway with your camera to create different images. Moreover, when you exercise, you can change your exposure speed, which will produce a series of amazing pictures.：

Faster shutter speed can solidify the instantaneous action. This picture taken by Chris Jones captures the moment of the Impala galloping. In addition to the shallow depth of field, the background has been completely distorted, so that the movement of the Impala can be clearly displayed.
Photo Tip: How to combine shutter speed and aperture settings has an impact on photography, as long as you know this, photographers can freely choose the picture they want to capture. The camera's fool function is very useful in many cases, but understanding the basic working principles of some cameras will help us to produce more creative works.：
