How to make the picture clearer

For photography, clear focus is the basic requirement, but for beginners, each photo can focus for clean has the certain difficulty. There are many influence factors in clear focus, if you can't grasp well, it is difficult to obtain good results.

1. To prevent vibration. Vibration can make the image fuzzy shaking in the photo, even if the focus is very accurate, it can also affect the clarity of photo. The reasons cause vibration in general, there are two: one is the camera shake, namely in the press the shutter, the camera as a result of instability and shaking. The second is moving subjects, that is, at the instant of the camera shutter release, the subject itself in moving, and shutter time is short, no living dynamic solidification, hence the image fuzzy.

To prevent vibration, you can take measures from the following three aspects:

(1) Put camera on a tripod. If limited by shooting conditions, unable to support the tripod, you can also be converted to a single leg.

(2) Shorten the shutter time (generally use 1/250 second) to minimize camera shake vibration produced by image.

(3) The correct way to hold camera. In the case of no tripod, holding camera posture is correct or not will directly affect the stability of the camera.

To overcome the subject's own motion blur, there is only one kind of method that is to shorten the shutter time. As long as the shutter time conditions allow, the shorter time, the better the results.

2. Do not one-sided pursuit of small aperture. Beginners think small aperture can increase the depth of field, which will make the image clear, so often use it in all occasions, the aperture has been very small, especially in focus, the more will believe small aperture can help them out. But the final result is often not ideal, because using a small aperture will lead to the extension of the shutter time, and thus make the camera vibration produces enough negative impact. So, one-sided pursuit of small aperture is not the best, the right approach should be used for short periods of time the shutter and a tripod.

3. Knowing the characteristics of the lens. Many people think that the smaller the aperture of the lens use, the greater clarity they will get. This view is not correct. In fact, the best condition of lens imaging is its biggest aperture to shrink after 2-3 file. Such as a lens with maximum aperture F2.8, when the aperture is close to F5.6-F8, the image is the best.

4.Pay attention to the relationship between the line scene and the main body. The size of the color contrast between the main body and the contrast will affect the vision of people, on the basis of the focus, big contrast between the main body and line scene, images looks high resolution; If the color contrast is small, looks low resolution images. Therefore, to make the main body in the picture is very clear, consciously choosing high contrast line scene is very effective.
