The quality of the camera lens is to affect the photo sharpness is one of the key outstanding lens resolving power can render more detail, is why the so-called "mirror Emperor", "Ming-Ching" always asking for a lot of money, and many photographers dreaming of dream Yiping! However, funds are not sufficient players to pursue the expensive lens may be somewhat unrealistic, especially novice just entered the field of photography, learn some tips and basic concepts, even using a cheap lens, or even you just take the general DC in the photo but can still shoot clear, sharp photos.
One camera enough stability
Sometimes the picture looks sharpness poor because of the sake of the image mode burnt, camera shake also may be a moving object caused. In order to show the situation atmosphere or the presentation of some of the creative approach, we often will see photographs of rock about burnt, but that is the mood and beauty inside. For general photography, even if it is life according to the most simple, leave alone the control of light and composition, the main clear and explicit is a basic requirement.
No matter what kind of shooting conditions, to capture clear photos first step is to predict with confidence the camera, you can try to take the camera close to the body clamping arm, if you think that stability is still unsatisfactory situation allows the viewfinder is good way. Or will rely on the body in the vicinity of a solid matter, railings, columns, etc., so that when shooting better stability. To to Xiaobian own experience, you can also try to stop breathing in the moment of pressing the shutter, and also helps to reduce camera shake.
Of course, the most foolproof method is to use a tripod and shutter release shooting, but also pay attention to when using the tripod surroundings are safe and secure, there are tripod robust enough, or any sign of trouble will make the tripod shaking or dumping, the worst case, the camera may also therefore broke it.
Two, to strike a balance between high ISO and security shutter
If it is not so adequate in the light, be sure to pay attention to the safety shutter, security shutter is 1 / lens focal length, such as the 100mm focal length in the shooting, the shutter speed of 1/100s or faster is the so-called the safety shutter. Blessing through the camera or lens image stabilization system can also provide better security shutter, but it should be noted that the safety shutter is not absolutely safe, anti-shake system is not a panacea, each person's situation is different, you want to measure their handheld shooting stability limits.
If no tripod auxiliary aperture have opened to the maximum shutter speed, you can try raised the ISO to improve. But to note is that high ISO is accompanied by noise interference, excessive noise will affect the image quality, imaging seems loose. As for you to ask the upper limit of the high ISO where this is determined in accordance with the level of the camera, some ISO 800 has reached the limit, some of the ISO 3200 quality is still an easy ride....
