Matters needing attention in the introduction of digital photography

Nowadays, many photographers like to split colors into monochrome or black-and-white works to highlight their works. This is a good method, but once you watch more such works, your sensitivity to color will also decrease. This is not a good thing. I have carefully arranged the following contents for you. I hope you like it.

1. Operation and control of learning equipment. Since you want to learn photography, it is necessary to have a digital camera with basic functions. Although the function is simple, you must know every function and actual operation, and do well the seemingly simple functions such as ISO, aperture, shutter and exposure compensation. Actually pulling each other, bringing out many methods. When all the camera functions can be operated smoothly, we can find out the best way to shoot in the future.

2. Learn to look at pictures. This is what many people don't understand. Most people look at pictures systematically to see whether they like them, whether the model is beautiful, whether the figure is good enough, whether the scenery is beautiful, whether the clothes are special and so on. But this is the wrong way! I suggest you try to see more pictures taken by others during this period. In terms of photo content, the works of so-called domestic photographers or artists are often not as good as those of some unknown photographers abroad. Just look at those works that are called masters at home, and those are foreign. Learn as much as possible, diversify your works, put aside the names of the masters you have heard, and find out the works of photographers you think you like very much.

* Portrait photos, don't look at those beauty photos, look at some models taken by ordinary people. This kind of photos often need more efforts in composition and light and shadow control. Look at other people's pictures and learn about their composition, shooting angle, possible aperture and focal length. Look at the direction of light and shadow, understand the possibility and arrangement of the other party's use of light, and even what equipment may be used, as well as the shooting time and so on. Finally, there is the arrangement of colors on the screen, which is more easily overlooked. Color is also an essential item in photography. Through other people's works, we can also see the photographer's arrangement of colors.

* From the perspective of creation or documentary, whether the work is intentionally arranged or unintentionally obtained. Documentary photography needs a lot of luck, but when there are many good works, it also shows that photographers have a very strong photographic vision. Creation is to look at it from all angles and understand the ability that every photographer can control.

Nowadays, many photographers like to split colors into monochrome or black-and-white works to highlight their works. This is a good method, but once you watch more such works, your sensitivity to color will also decrease. This is not a good thing, so when studying, color works are still the direction of efforts.

* It's good for you to absorb as many diverse styles as possible.

3. Learn composition and theory. The more works you watch, the more you need to learn the rules of composition and related theories when you enter the actual shooting stage. There are many such books on the market, you can learn to imitate them. In the study of composition, some people will say that it is unnecessary, but they must learn. Good composition can make the work more acceptable to the audience. Although it is not absolute, it is the experience gained after statistical analysis. Then it will be transformed into the law of composition that we believe in until we can blend in naturally, and then there is no need for so-called composition.

But before that stage comes, the rules of composition still need to be learned. Of course, for theoretical things, you can look at some books by truly internationally recognized photographers. There are many books in foreign languages, and many people in China can translate them and even become their own theories. The suggestion is to directly translate foreign documents. It is convenient to translate the parts that you don't understand now, so don't be confused by those scattered Chinese documents.

4. Learn to adapt to and control light and shadow. From the moment you see it, slowly, you will understand the most important composition in the image: there is; It is certain that where there is light, there is shadow. What kind of light will produce what kind of shadow is certain. After understanding light, I began to learn how to control light, from natural light to artificial light, from hard light to soft light, to understand and use it, and to distribute light according to the picture I want, so that light and shadow can be easily controlled by myself and the best image can be easily obtained.

5. Learn darkroom system. This is the last part of the process. The image records all the original color light in the camera, and then enters the computer darkroom. At this point, it is my ultimate control over the work. In order to make the image more perfect, the necessary post-processing cannot be reduced. From the simplest brightness and contrast, to the adjustment of color temperature, even the control of high and low light exposure area, or various synthesis, beauty editing, typesetting and so on. , all need to learn. Although the work does not necessarily have editing, composition and other actions, if the work needs to be expressed in this way, these are also a method of image processing, so it is necessary to study at this stage.

Introduce the meaning of the numbers on the camera lens.

AI: automatic maximum aperture transfer technology. Published in 1977, used for manual lens. Logo does not appear in the lens name, and the smallest number on the aperture ring of AI lens is green.

AI-S: automatic shutter index transfer technology. Published in 198 1 for manual lens. There is no logo in the lens name, and the smallest number on the aperture ring of AI-S lens is yellow.

AF: autofocus technology. The AF in the name indicates that this is an autofocus lens, but the lens itself has no motor. If the body does not have a focus motor, it cannot focus automatically.

AF-I: 1992 introduced the lens with built-in motor and CPU contacts, which is mainly used for professional telephoto lenses. Has been replaced by af-S.

AF-S: autofocus lens with built-in SWM ultrasonic motor. This kind of lens can also achieve autofocus on low-end cameras such as Nikon D5 100/D3 100 without a body motor.

ASP: Indicates that an aspherical lens is used in the lens.

CRC: short-range error correction system. The system enables photographers to obtain excellent image quality when shooting at close range and increasing the focus range.

D: focal length data transmission technology. D-lens supports 3D matrix photometry.

DC: defocused image control. Nikon original lens can provide unique zoom control function. Its main feature is that it allows fuzzy control of the foreground or background of a specific object to obtain better defocus imaging.

DX: Special lens for APS-C camera, with small image field design, can't be used on Quan Huafu fuselage.

Ed: That means ultra-low dispersion lenses are used in the lens.

G: G lens cancels the traditional manual aperture ring. G lens often appears on Nikon's latest lens together with AF-S, showing an upgrading trend.

Macro: Macro lens.

N: It was once used to represent a new lens, but now the N with a hexagonal bottom on the lens means that the lens is coated with nanocrystals.

PC-Shift: move the lens.

Radio frequency: rear group focusing technology.

S: Thin, appearing on some thin lenses.

SIC: super composite coating.

TC: rangefinder.

VR: image anti-shake system. This shows that the lens has anti-shake function.
