With the right use of blurred areas and motion blur, photographers can successfully achieve the goal of "everything is in motion", even with a still camera and subject selected. Therefore, time can be seen as a tool to enrich the meaning of the work by capturing the movement of the subject with the camera.
Time
In the blink of an eye, cameras are able to capture fractions of a second, a tenths of a second, a hundredth of a second, a thousandths of a second, and even shorter, these brief moments are almost imperceptible to humans. In a very short period of time, the shutter of the camera is opened, and a large amount of light hits the sensor, and although the thousandth of a second is short, what happens during this time is far more than we can imagine. When the wind blows the flowers and plants, the flowers and plants sway with the wind, and the moment a drop of water falls. However, the camera can break it down into a large number of individual **, capturing every tiny detail and allowing people to observe the moment more clearly.
Shooting shaking
An essential goal for most photography enthusiasts is to capture clear **. However, it is difficult for the human body not to produce any shaking or shaking. This jitter is more noticeable over long periods of time when the subject moves relative to the position of the sensor, and multiple images overlap each other, resulting in blurry images. This is due to the tremor of the photographer's own muscles, which is often unavoidable. This jitter occurs in different directions and can have some negative impact on the image. From the viewer's point of view, they may see this as a technical flaw, but it doesn't necessarily completely destroy the quality of the image.
In order to reduce blur when shooting, we can fix the camera and adjust the time in different ways and techniques. First of all, pay attention to the posture of holding the camera. A common position is to place the bottom of the camera on the palm of your left hand, support your left arm with your upper body, and hold the shutter-release key with your right thumb and forefinger. This pose can effectively suppress shooting shake for shorter periods of time, such as 1 125 seconds to 1 60 seconds.
However, the minimum effective ** time also depends on the focal length of the camera. The longer the focal length, the more likely it is to blur due to shooting shake, so it takes a shorter ** time to avoid blurring.
When shooting handheld, there's a rule of thumb that can help you avoid shooting shaking: Time should never exceed the reciprocal of the focal length. For example, the maximum safe** time for a 200mm lens is 1 200 seconds. However, for small sensor cameras, you need to multiply this value by the camera's crop factor to get the corresponding minimum safe** time.
In short, knowing the focal length of the camera, the posture of handheld shooting, and the rules of thumb will help you better understand how to avoid shooting shake and get sharper images.
Intentionally blurred shooting: panning
Panning is a photographic technique that uses the lens to track the target scene so that it is almost at the same speed as the target scene, so as to achieve the effect of blurring the background and strengthening the target. It is generally used to follow the pan horizontally to express the intense sense of speed, or to follow the pan vertically to express the burning or ** feeling.
It is commonly seen in the following scenarios:
Photograph objects that are perpendicular to the camera and traveling in a straight line, such as a car on a straight runway
Swing the beating of people and animals that run;
Shake flowers fluttering in the wind, such as lotus flowers.
The procedure is as follows:
Set the manual M stop or the shutter priority TV S stop;
The fixed shutter speed is 1 30-1 60, and the shutter speed needs to be fixed in the appropriate gear during panning, because the speed of the lens rotation and the speed of the moving object need to be synchronized during the shooting process
The sensitivity is automatic, and the aperture can reach the correct **
Focus should be fast and accurate;
Shoot in a stable posture and use continuous shooting mode.
Note that after pressing the shutter, you should not stop rotating the lens as soon as you press the shutter, the lens should continue to rotate some distance with the movement of the subject, and at the same time, you should not press the shutter too hard to avoid shaky and blurry.
