How to improve the clarity of photography

For photography, clear focus is the basic requirement, but for beginners, for each photo can clear focus is 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. Silhouette, moreover, filming and photographing skills can improve clarity on visual effect, and largely improve the pictures of the appreciation of the beauty and art. Few words said, and then the author will these photography skills to teach you.

A. How to make the picture clearer?

1. To prevent vibration. Vibration can make the image fuzzy shaking in the photo, even if the focus is very accurate, it also can affect because of this knot like clarity. Causes of 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 motion, and shutter are short of time, no living dynamic solidification, hence the image fuzzy. To prevent vibration, you must suit the remedy to the case, you can take measures from three aspects:

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

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

(3) The right way of degraded. In the case of no tripod, degraded position correctly 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 the better the results.

2. Do not one-sided pursuit of small aperture. Beginners think small aperture can increase the depth of field, will make the image is clear, therefore, they tend to all occasions, the aperture has been very small, not sure 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 used, the greater the clarity of imaging. This view is not correct. In fact, the best condition of lens imaging is its biggest aperture to shrink after 2-3 files. If a maximum aperture of F2.8 lens, when the aperture closed to F5.6-F8, the imaging is the best.

4. Pay attention to the of relationships the line scene with main body. Main body and color contrast between the two line scene sizes will affect the vision of people, on the basis of the focus, the main body and line scene, big contrast between 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.

B. How to achieve good silhouette photographs?

1. Fully show the body characteristic of the silhouette theme, vivid and background together will form, It can be said that the body is language, background is tone, let the creator to ponder and experience, this is the beauty of silhouette photographs. The subjects in silhouette, almost no color and detail, so the shape characteristics of the subject requirement is high, which requires the author to carefully selected based on the performance effect of the late shooting Angle and body shape, fully demonstrate the shape characteristics of the subject, aesthetic feeling and vivid.

2. The silhouette photographs for make full use of the subject and the background difference by light. Generally speaking, we can use the sunrise and sunset when the backlight, because at this moment the most soft light, looks and not dazzling, it is a good time to shoot, only ten minutes or so commonly, also can use outdoor and indoor artificial caused by light difference or the sky and the natural reflection of the water.

3. Exposure to follow the principles of rather than less exposure than over exposed, on the basis of background light part of the spot metering, a serious shortage of this to make the main exposure, the formation of strong silhouette.

4. When the frame as a proportion of the subject in the picture is too small, or pictures of blank space is drab, you can creatively use silhouette as prospects, through a black silhouette can oppress the audience visual to subject, black silhouette at the same time also won't distract the attention of the audience. We can even use in silhouette as the main body frame, form variation of various shapes, square, round, or make the usual scene has unique picture form feeling, increase the depth of the picture.

C. How to use the weak light to shoot?

1. The collocation of reasonable aperture and ISO. Photography of the most fundamental laws of nature also apply to low light photography, the larger the aperture, shutter speed is higher, the lower the ISO, the higher the quality, the longer the exposure time, the possibility that noise is bigger; Suggest you use making aperture to obtain maximum depth; ISO is very low, in order to reduce unnecessary noise, generally USES the ISO 100.

2. Stable long exposure time. The biggest characteristic is to "long" weak light photography shooting time, you often need a few seconds, or even tens of seconds to complete you, therefore, a solid tripod is necessary; In addition, shutter release may appear when pressing the shutter can effectively reduce jitter.

3. Trying out for x 3 environment. To fasten on a digital camera with a tripod, adjust the ISO - 100, aperture making, according to the 5 seconds, 10 seconds each a photo shoot, and 20 seconds from captured three photos on the accurate judgment of scene lighting - often need to use B door for such a long time exposure, according to the results of three test pictures to determine the exposure time in the end.

4. Never use RAW format. Taken in long time exposure such extreme cases, RAW format to provide the quality of the effect will be much higher than JPEG format, do not save memory space, the dedication of the image only can bring the best photos.

5. Keep trying, keep fresh. Creative potential is very low light photography, completely don't have to follow a fixed aperture, shutter speed, ISO setting, constantly trying new possibilities, using different time complete works with light
