How to master the exposure time

Lead: In the process of photography, it is very important to set the aperture value and shutter speed of the camera. Annie Griffiths Belt, a famous photographer of National Geographic, collected the works of National Geographic magazine 10 photographers, and commented and analyzed their thinking when taking pictures. This time, she will teach us how to set the appropriate shutter speed to stop time. Let's study 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 at school, when I was working for Minnesota Daily. After graduating from 1976, Belt joined the Worthington Globe. He has won awards from the National Photographic Association, Associated Press, International Women's Organization and the White House Photographers Association. Her works have been exhibited in new york, Moscow, Tokyo and other countries, and she also gives lectures in some schools regularly. She is the first female photographer in National Geographic magazine.

Like many landmark buildings, the Colosseum has been photographed thousands of times. However, in this wonderful photo, Heather? Perry blurred this historical site with a long exposure, presenting a picture that we have never seen before.

Shooting skills: Every photo actually needs a certain amount of exposure. A photograph can be an image recorded within a fraction of a second or a few hours. Many people never realize that they can use time as a creative tool in photography. Remember, long exposure or instant exposure can adjust the shutter speed.

In this simple photo taken by Kachin Ge, the slow exposure camera records the swimming movements of the newly hatched turtles, but the instantaneous exposure will freeze a series of movements of the turtles. This imaging photo left a deep impression on the little turtle's swimming.

Tip: When the shutter is pressed, many photographers don't realize that they can create photos of different images by changing the speed of the camera shutter. Slow exposure can record the process of motion, and the shutter will capture a moment in the blurred motion.

Exposure time allows me to record what we can't see with the naked eye. In this Eva? Troy Turk and John? In the beautiful photos taken by Mr. and Mrs. Eastcott, we can see that these wild horses appear in front of us in a new way, and the fuzzy feet, tails and manes constitute a real running scene.

Shooting tips: The method of choosing a long exposure speed and tracking the ongoing action is called lens shift shooting. One of the joys of moving lens shooting is that photographers never know what the final imaging result will be. In a sense, shooting can sometimes show things that we can't see with the naked eye.

This Bruce? The smart photos taken by Dell made us feel that we were on the moving train beside him. The blurred scenery near is dizzy, but the scenery far away is extremely clear.

Shooting skills: when shooting from moving objects, try to shoot with a wide-angle lens at a slow exposure. The close-range background will blur faster than the long-range background, and the shot picture will definitely make the viewer dizzy.

Although photographers often can't take good photos in poor light, slow exposure can sometimes take amazing photos, and the blurred action in the picture makes this kind of photos different. Joe? A pair of hummingbirds photographed in Petersburg is a successful example of this unexpected effect.

Shooting tips: Even if you shoot wild animals and plants, you can shoot unexpected and unusual pictures with low brightness and long exposure. Don't complain about the poor light, use it to take innovative photos. Wonderful things will happen!

Long-term exposure to the rapids of rivers presents a wonderful canvas-like scene. In this photo, we see the swift river revolving around a red maple leaf. Blur the river by using slow exposure, photographer Mike? At the foot of the mountain, a clear-cut leaf picture is outlined in the abstract water.

Shooting tip: You don't need a long exposure time to blur the torrent. Sometimes portable cameras can capture this effect. But bring a tripod, so you can try various exposure times and see which effect is your favorite.

It is this sense of movement that makes this photo of a leopard fighting so successful. Some parts of these big cats, such as claws and ears, are very clear. But the vague limbs attract us deeply, suggesting that powerful muscles are trying to push this animal. Photographer Richard? Toit chose a perfect exposure speed to show this action.

Shooting tips: Although we all try to shoot wild animals at a faster exposure speed, slowing down the exposure speed may present a more fascinating picture. The goal of photography is not always to get exceptionally clear photos.

In an abstract color vortex, this clear trunk prevented this seasonal image from getting out of control. Imagine how many autumn photos there are, but what about Conrad Voss showed us a new perspective.

Tip: Remember, photographers can also exercise. You can rotate, run and swing your camera to create different images. And you can change the exposure speed when you exercise, and you will take a series of amazing photos.

Faster shutter speed can solidify instantaneous action. This photo taken by chris jones captures the moment when impala flies. Coupled with the extremely shallow depth of field, the background is completely blurred, so the impala's movements can be clearly displayed.

Photo Tip: How to combine shutter speed and aperture setting to affect shooting? As long as we know this, photographers can freely choose the pictures they want to capture. The camera's fool function is very useful in many cases, but understanding the basic working principle of some cameras will help us shoot more creative works.
