How to capture moving objects instantly in photography.

The action of "freezing" allows you to re-examine the world and create a truly spectacular lens. This is not possible with automatic mode. In order to get good results, it is very important to learn how to "freeze" moving objects. Special camera settings, concentration and constant practice will soon be effective.

Why do I need to "freeze" photos?

Surprisingly, the photographer managed to freeze some photos of a fast moving process. This is because we can't see it in our daily life. The human eye can see what is happening as a whole. He can't tell the stages of exercise. Only in photos can you see how water droplets or glass fragments fly away. The "freezing" of the camera makes it possible to study all the nuances and evaluate the smallest details. For example, water drops fall into the water. Usually we can't see funnels and funnels in splashing water. This also applies to the photography of sports competitions. The facial expressions of athletes at the critical moment of take-off or goal, flying motorcycles and dust wrapped in dust. All these are valuable experiences for photographers and audiences.

How to "freeze" a moving object

When planning to create a painting with "freeze-frame" action, you can't rely on opportunities. Occasionally, you can't take a masterpiece or at least an interesting photo. It's important to be prepared in advance: use the experience of professionals, learn how to correctly configure cameras, and watch more works by excellent photographers. Only after these stages can you get spectacular photos that the audience is interested in. At first, it was not easy. You must try to catch a moving object at a critical moment. Not only novices, but also professionals may encounter this situation.

When shooting sports, it is important to pay attention to some nuances.

Shutter speed setting

The most important parameter for creating "freezing" of moving objects is exposure. It should be as short as possible. Setting this parameter makes it most convenient to work in "shutter priority" mode; For different manufacturers, it is represented by "S" or "TV".

To "freeze" the moment as much as possible, you'd better choose the fastest shutter speed. Depending on the brand and level of the camera, it can reach 1/4000 seconds or 1/8000 seconds. In an instant, the moment of movement is frozen.

Sensitivity (ISO)

The simplest method is to "freeze" the photo effect under sufficient light or using high aperture optical elements. If the light is insufficient, we should pay attention to photosensitivity. In order to ensure that the picture will not be too dark under the slow shutter, it is necessary to increase ISO. You can also use automatic sensitivity detection in shutter priority mode. In this case, the photographer sets the opening time of the shutter, and the camera itself will determine the required sensitivity.

If the camera doesn't have automatic ISO, you need to choose the appropriate value yourself. After several tests, you can set the perfect combination or use the photometric sensor, which should show zero deviation.

Lens focusing

At work, you can use not only professional cameras, but also cheap cameras.

One option is to set tracking autofocus. Therefore, the camera will monitor the movement of the object and will not allow it to leave the clear area. But this is ideal. In fact, an autofocus error may occur.

Experienced photographers suggest using manual focusing to freeze moving objects. Before shooting a moving object, you must choose a specific point and focus on it. This can make the picture clearer and better, and can better control the shooting process. You can choose the most suitable camera location relative to the location where the decisive event occurred.

Shutter delay

It is important to explore all the functions of the camera. Whether it's standard or personal. When freezing, it is very important to know how long it takes from pressing the shutter button to the shutter. Many fans press the button at a critical moment, and the shutter doesn't work at all. As a result, the best opportunity was missed. Usually, it is impossible to repeat them.

Despite the continuous improvement of photographic equipment, even expensive professional cameras need time to operate the shutter. For cheap cameras, this time span is even longer.

In order to determine the time required for a specific camera, some measurements must be made in advance to avoid missing the moment when the moving object is "frozen". It's simple. It is necessary to do some Shoot to evaluate how the photos you get lag behind the photos when the photographer presses the shutter button. Therefore, the time interval can be determined and considered when shooting. Usually, this is an instant. However, when using fast moving objects, they may play a decisive role. It's over. Practice is very important.

Flash usage

In some cases, to "freeze" moving objects, you must use the flash on the camera. This is a stand-alone device connected to the camera. External flash is very helpful in some cases and helps to achieve excellent results.

When to use the camera's own flash:

1, shooting in a dark room or shooting in a street with insufficient light;

2. When the moving object approaches the photographer.

Even if the main body moves quickly, the light pulse emitted by the flash will freeze the movement. Similarly, a beam of light highlights the subject, increasing clarity and contrast, and separating it from the background.

What are the possible difficulties and how to solve them?

With the "freezing" of moving objects, three problems often appear:

1, the main melody is fuzzy;

2. The image is too dark;

This picture is too bright.

If the target is not reached and the action is not frozen, the shutter speed may be set incorrectly. You should try to make it shorter.

If the background is clear and not the main object, the error lies in focusing. You should try this option. Try different automatic modes first. If they can't do it, please adjust the focus manually.

If the shutter speed is set as short as possible, there may be underexposure. The shutter opening time is too short, and there is not enough light to enter the matrix. This may happen in a dark room when taking pictures on cloudy days or at night. You can slightly extend the shutter speed, increase the ISO value or enlarge the aperture.

On the contrary, when shooting moving objects on sunny days, the sensitivity should be minimized and the aperture should be close to the average. Therefore, the frame will not be highlighted.
