How to take sharp photos? 10 skills you need to master

I believe many friends have had such doubts. Obviously, they bought a decent set of photographic equipment, but they couldn't take such clear and sharp photos as the master's works. In fact, many times, I don't know enough about my own equipment, or the shooting method is wrong. Focusing mode, camera attitude, camera settings, lens and many other aspects will affect the clarity of photos. Before you can't wait to pick up the camera, you can read this article about how to improve the definition of taking pictures. So as to better ensure that beautiful scenes will not leave regrets in their own hands. The influence of lens For digital cameras, the lens is the most important link that affects imaging. The emphasis here is not on choosing expensive equipment, but on how to make better use of the lens in your hand and get as clear and sharp an image as possible. First, confirm the best aperture of the lens. First of all, we should know more about the lens in our hands. What is its best aperture? For most ordinary lenses, the aperture is the best at F5.6-F 1 1, but simply following this rule is a bit silly. As long as you have a tripod in your hand, you can fix the camera on it, and then test the image quality at each aperture until you get the clearest available aperture of the lens. This is because some lenses have adopted the design of large aperture optimization, and they still have good imaging under the condition of large aperture. Second, don't use extreme focal length. For ordinary zoom lenses, unlike fixed focus lenses, the imaging quality of all focal lengths cannot be guaranteed to be consistent. The conservative approach here is not to use the extreme focal length of the lens. For a lens with a focal length of 75-300mm, the resolution of the photos taken at the 280mm end must be higher than that at the 300mm end; For a lens with a focal length of 70-200mm, the imaging at the end of 100mm will be better than that at the end of 70mm. Although this rule can't be applied to all shots, it is quite practical for most ordinary shots. Third, know your lens. Although it is more important to actually use it after buying it, you should do your homework first and know your lens. For example, some lenses with anti-shake are recommended to be turned off when using a tripod, and some lenses are recommended to be turned on when using a tripod. Fourth, the lens quality is not high. Usually, we don't encounter hopeless shots. Generally, after reducing the aperture, we can get the ideal definition. However, some lenses have their own defects (such as Sony E 16 F2.8), and the edge imaging quality is not good. At this time, even if the lens is reduced to the optimal aperture, the obtained image may not be satisfactory. For these lenses, you should avoid buying them. If you buy it, you should choose the subject carefully to ensure that the subject is not in the edge area of the picture. There are many reasons why the photos are not clear because of the influence of shooting control, and the correct operation of the camera is an important part. How to hold the camera and press the shutter button can improve the stability of the camera and the chances of taking clear photos. 5. Correct focusing operation It can be said that determining the correct focusing point is the first step to obtain a clear image. When shooting portraits, we need to aim the lens at the people's eyes, not the shoulders, nose or forehead. When you haven't mastered the accurate usage of manual focusing, setting the focus at the eyes can effectively improve the success rate of portrait shooting. Another easy-to-occur focusing problem is out-of-focus caused by shallow depth of field after re-composition after focusing. The reason for this problem is usually that the entry-level camera SLR camera does not have enough focus, or directly adopts central focus, but the camera is rotated greatly to change the focal plane when re-composing. If you like to re-compose after focusing, please minimize the camera movement after focusing. If your camera has enough focal length, you are still used to moving the focal length left and right to meet the needs of composition. For some contrast-focused non-reflex cameras, the focus area is never a problem, and it is necessary to focus by moving the focus point to match the composition. Sixth, a stable shooting posture It is a cliche to maintain a safe shutter speed when taking pictures (usually the reciprocal of the focal length of the lens, pay attention to the equivalent focal length of 35mm), but it is a prerequisite to maintain a stable shooting posture and a clear image in the environment. There are no clear requirements for grasping the camera posture, but the following requirements need to be followed, and the rest is practice. The picture comes from the internet. 7. When the shutter button is pressed correctly, we don't need to squeeze it hard, which will not only cause the vibration of the camera but also accelerate the aging of the shutter button. The correct way should be to simply cover your fingertips on the shutter button from back to front (or from outside to inside) to focus, and then press it gently to shoot. Camera parameter adjustment and post-processing In order to get a clear image, increasing the shutter speed is the most direct solution. As long as it is higher than the safety shutter of the lens, the success rate of taking pictures is still quite high. In addition, some post-processing methods after taking photos can also improve the clarity of photos. Eight, improve the ISO value when shooting high-speed moving objects, the faster the shutter speed leads to underexposure. At this time, the ISO value will be raised. For the current SLR and mirrorless cameras, the problem of picture purity under high sensitivity has been greatly improved, and the ISO sensitivity can be appropriately improved. Nine, appropriate sharpening treatment Generally, the sharp pictures we see are all sharpened in the later stage. If you usually use RAW to record images, you can use RAW software from different manufacturers, or LightRoom, Aperture and other software to operate on the computer. If you choose JPEG file format to save trouble, you can directly use the sharpening settings in the camera, and often you can achieve the desired effect by appropriately increasing the files 1 and 2. Moreover, human eyes are more sensitive to the contrast of the picture than to the clarity. If the contrast is properly improved, the effect can sometimes be sharpened. X. The last step is to sharpen again. Because photos have different uses, we don't need to sharpen the image completely at first (for example, sharpen it with RAW now and then output it to Photoshop), but sharpen it when we finally output the photos. At present, we mostly use the photos taken for network purposes, so it is different from sharpening when outputting printed photos. So the best way is to leave the sharpening process to the last step, which leaves us room to output pictures of different sizes and uses. Summary: This paper only introduces the basic means to get clear and sharp pictures, and mastering these basics can ensure that you can take pictures without making mistakes. However, there are many ways to get a clear image. For friends with deep pockets, they can pay more attention to the image sharpening process in the later period when ensuring the basic shooting equipment (cameras, lenses, tripods, etc.), which has a great influence on the image.
