Three Simple Ways to Avoid Blurred Photos
The exposure of a photo mainly depends on three elements: aperture, shutter speed and sensitivity (ISO). The combination of these three elements will form different exposures, and different settings will be used to achieve standard exposures in different environments.
2. The reason why the photo is blurred:
1. focusing error: if the scene is darkened with a large aperture, the blur is particularly obvious.
2. The shutter speed is too slow: this is the most prone to emotional distress.
3. Briefly describe the principle of shutter:
Shutter is a device to control the time when light enters the camera, which can be understood as a door on the camera. When the door is open, light enters the camera, and when the door is closed, light cannot enter. The opening time (shutter speed) will affect the amount of light entering, thus controlling the photo exposure.
4. The shutter said:
In a camera, the shutter speed is generally expressed as 1/X (seconds), such as 1/400, 1/200, 1/30,115, etc. The larger the value, the longer the shutter opens and the more people enter the camera.
5. The shutter affects the exposure:
The length of shutter opening time directly controls the amount of light entering the camera. The longer the opening time, the slower the shutter speed and the brighter the picture. The shorter the opening time, the faster the shutter speed and the darker the picture.
With the aperture and IS0 unchanged, the slower the shutter speed, the more light entering and the brighter the picture.
6. The reason for the paste when taking pictures:
1. photographer's own problems: hand shaking is inevitable when shooting with hands. Even the best photographer can't guarantee that there is no hand shake. The slower the shutter, the more serious the jitter problem.
2. The subject's question: The slower the shutter, the longer the exposure time. If the subject is moving during the exposure process, the photo will leave a "residual image", which makes the photo look unclear, which is often encountered when shooting children or pets;
7. Solution:
3. Adjust the camera aperture and ISO value: If the blur is caused by the slow shutter speed, then we just need to speed up the shutter speed! To improve the shutter speed and correct exposure, then: increase the aperture to let more light enter at the same time; Sensitivity (IS0) should be improved, and it is easier to absorb light: the above two emotions are carried out simultaneously.
8. Safety shutter:
Safety shutter (seconds) = 1/ focal length (in mm).
For example, if you use a focal length of 50mm, then 1/50 seconds is the safety shutter. At this shutter speed or above, hand shaking will not affect the exposure; For example, if you use a lens with a long focal length of 300mm, then your safety shutter should be at least 1 1300 seconds. But note that in general, the safety shutter should be no less than 1/30 seconds.
9. Solution
1. You can keep the shutter speed at an appropriate value by using the fill light tools (constant light, flash, etc.). ) is within the effective range of supplementary light, so the aperture does not have to be large and the ISO value does not have to be high.
2. Use a tripod: Avoid hand-held shooting. Choosing a stable tripod allows you to use the slow door and keep the photos clear.
