Theoretical knowledge of photography

Theoretical knowledge of photography, photography is not taken casually with a camera. For beginners who are new to photography, they still need to know some basic knowledge first, so let's share the theoretical knowledge of photography with you.

Knowledge of photography theory 1 1. Master the use of photographic equipment.

For camera settings, according to my experience, the use probability of "aperture priority" accounts for 80% (mainly to control the depth of field); The priority probability of shutter use is about 15% (dynamic subject shooting control), and the probability of manual gear use is only 5% (when it is impossible to focus accurately). So it is generally set to "aperture priority" mode.

Conventional shooting modes, including large aperture, night scene, portrait, photo, video, interesting AR and so on, have their own advantages and disadvantages. Usually use a large aperture, night view, portrait, video, the feeling is ok. I use more professional mode, time-lapse photography, streamer shutter and slow motion, which should all be in my video. These are mostly manual adjustments. I like manual adjustment very much because it can make us think.

It is easy to generate creativity and interest. Photography is an art, since it is an art, there is no end. When we learn photography, we need some theoretical knowledge as the direction when we are beginners, but what is more important is innovation. Therefore, if you use a mobile phone for photography, you must know the settings, parameters and functions of the camera on the mobile phone, so that you can use it flexibly. Through constant practice, practice makes perfect, and we can make continuous progress and improvement on the original basis to avoid popularization.

For SLR camera photography, I suggest you be familiar with camera control first. This step is simple. Just put the camera and instructions on the table and play with them a few times. Although the camera manual is relatively thick, there are not many parts that need to be read carefully. Be sure to read it. I have avoided playing photography for several years, but I still have a little knowledge of basic common sense.

Second, learn the basic theory of photography.

Any subject has a theoretical basis, and photography is no exception. If you want to take good photos, you must master the basic photography theory. Such as the types and characteristics of light; Types and characteristics of colors; Light ratio, hue, hue, exposure, exposure compensation, depth of field, how to control depth of field and so on. At present, there is little systematic teaching of the basic knowledge of photography theory on the Internet. Next, I will publish an introductory tutorial on photography through a column and share how to learn photography systematically.

I hope everyone will continue to pay attention to me. Three concepts: aperture, shutter and depth of field. Understand these three concepts, then try to achieve different depth of field with different shutter aperture combinations. If you can use this freely, you will succeed. The rest is to practice more and learn other people's photo settings. Imitation is also a kind of learning.

You don't have to read too many books at first, so it's easy to be scared. We need to improve it in the future. Again, interest, this is a toy. Where would it be hard to like it? I don't like online games, so I find it difficult.

Third, learn to use light well.

Outdoor, the light angle is the best in the morning and evening, and the light quality is the softest. At this time, the scenery photographed has beautiful light and shadow, strong three-dimensional sense and atmosphere, which is the best light for shooting landscapes, flowers and portraits. Especially the shooting of plants and flowers is more energetic in the morning light.

In the morning and evening light, the angle of the light source is the best, but attention should be paid to ensuring the perfect light receiving effect of the subject. It is suggested to use side light (front side light, side light and side backlight), followed by supplementary light to balance the light ratio. Try to avoid using front light and full backlight.

Usually portraits run out of available shooting techniques:

1. Side light and backlight for women can reflect the rounded outline and feeling of women.

2. Children, smooth and sunny, reflect children's sunshine and vitality.

3. Male, the light can be hard, modify the hard lines of the face, or light silhouette.

In the case of limited conditions, you can also turn on the flash of your mobile phone and turn on the constant light to repair your face. Contact outdoors in the morning and evening, because the light and color temperature at this time are very suitable for photography.

Fourth, learn photography composition.

1. Triangular composition in photographic composition technology. To learn and understand the composition of the trisection, we must understand the proportional relationship of the golden section. The principle of composition by trisection is actually the simplification of the golden ratio. Triangular composition is the most basic composition skill in photographic composition. Its characteristics are concise picture and bright theme. The disadvantage is that the composition is too stable, which can't give people a surprise and a feeling of "shine at the moment".

2. Picture composition in photographic composition skills.

The so-called frame composition, that is, using doors, windows, caves, etc. as the foreground to express the theme and clarify the composition method of the environment. Frame composition conforms to people's visual psychology and can produce a strong sense of space and perspective. Often through the framework to create a mysterious atmosphere. Give people a visual impact and highlight the theme.

3, curve S-line composition skills In photographic composition, S-curve is a' classic' in graphic curve composition. S-shaped curve composition is the art of photographic composition, hovering and swimming like a snake, giving people a beautiful and smooth feeling.

There are more than a dozen photographic composition skills, and I think these photographic composition skills are very critical and important. Mastering these three photographic composition techniques, other composition techniques will be solved.

Fifth, see more, practice more and communicate more.

How to learn photography? It is a big problem, and this article is just a simple guide. If you want to make rapid progress, you should watch more excellent photographs, practice shooting on various subjects and communicate with photographers. To sum up, see more, practice more and communicate more.

Theoretical knowledge of photography 2 The categories of photography are:

1, ink photography:

Ink photography is not a new technology, but a style. It is to unify traditional ink painting with modern scenery by means of photography. It can also be understood as the memory and feelings of modern people on traditional culture with the help of modern science and technology platform.

2. Holography:

Holography is a photographic method that can record and reproduce three-dimensional images of objects without lenses. It is a technology that can record the amplitude and phase information of light wave front from objects and reproduce this light wave when necessary.

3. Photo photography:

Portrait photography has always been an important form of photography to express the beauty of humanity and nature. Since the invention of photography, it can be said that photo photography has been running through it and has played several milestones in the history of photography.

4. Portrait photography:

The so-called portrait photography is a form of photography with characters as the main object of creation. Portrait photography is different from ordinary portrait photography: portrait photography takes the description and expression of the specific appearance and expression of the subject as its primary creative task. Although some portrait photography works also contain certain plots, they mainly show the appearance of the subject.

5. Still life photography:

Still life photography, compared with figure photography and landscape photography, takes inanimate, artificially movable or combined objects as the performance object. Mostly take industrial or handmade products, natural inanimate objects and so on as the shooting theme.

Photography theory knowledge 3 Three basic knowledge of photography: the choice of focus, the use of light and the use of focal length.

1, the choice of focus.

The quality of the portrait depends on whether there is a god in his eyes. If a person blocks his eyes or only leaves his back, it must be an incomplete portrait. Similarly, if you don't convey the charm of the characters' eyes when shooting a portrait, then the whole portrait is dim. Confirm where the focus falls when confirming the shutter.

2, the use of light.

Pay attention to the introduction of light when taking portraits. Different light will also get different photo effects, some of which can be compensated by PS, and some omissions caused by light can not be compensated by retouching software. In the case of smooth light, people can use uniform light to deal with some details of the face and better restore the change of skin color. The disadvantage is that it will make the characters' faces darker and the facial features slightly stereoscopic.

3. The use of cola.

Shooting portraits with different focal lengths will have different effects. 25mm is suitable for shooting full-length portraits, and can also record the scenery around the portraits. 50mm focal length is more suitable for shooting busts or close-ups of faces, which can create a three-dimensional face and is very suitable for middle-distance shooting. 85mm is the most suitable focal length for portrait shooting, which can bring a suitable description of the character's environment, realize the blur effect and easily shoot the finished art.
