Introduction to self-study of microphotography

Do you know what are the self-study courses for micro-photography? Photography is an instrument to record the beautiful moments in our lives, but many people don't know how to use it well, so as to record their own bits and pieces. Let's take a look at the introduction of microphotography self-study with me to record a better life.

Introduction to microphotography 1 1, photography aesthetics.

2. The layout of the theme.

3. Photography runs out.

Photography refers to the process of recording images with some special equipment. Generally, we take photos with mechanical cameras or digital cameras. Sometimes photography is also called photography, that is, the process of exposing a photosensitive medium by using the light emitted or reflected by an object.

Someone once said an incisive language: the photographer's ability is to transform the fleeting ordinary things in daily life into immortal visual images.

Three basic elements of photography:

Whether you know nothing about photography before or have made great achievements, whether you improve your photography skills in order to become an amateur photographer or a professional photographer for a living, we will all have a curse.

Photography is not only a discipline, but also a learned art. We can rediscover the beauty of life through the third eye, which is a very special place for photography. Next, Guiyang wedding photography studio-Century Bride will take you into the world of photography.

For any outstanding person who has made achievements in photography, the most important thing is to develop your "eyesight", that is, learn to observe. You must have seen some beautiful photos: "How I wish I could take such photos!" " "But if you just look at it, you can't improve your photography skills.

When you see a beautiful photo, can you tell why it is beautiful? Can you tell me how the authors of these works took these photos to make them so radiant? Of course, sometimes newspapers and magazines will tell you the brand and lens of the camera used to take these photos, and even the aperture and film used.

Introduction to microphotography 2 What is aperture priority? What's the use?

Aperture priority is the most commonly used exposure mode in our daily shooting (whether ordinary amateurs or professional photographers) (the other mode is shutter priority). Aperture priority, as the name implies, is to give priority to camera exposure with aperture setting, and other parameters are automatically adjusted to adapt to aperture setting. It can make the camera shoot at a certain aperture value to obtain the desired depth of field, blur, flare and other effects. In the aperture priority mode, as long as you set a larger aperture, you can shorten the shutter time and reduce the picture blur caused by jitter, which is especially useful for hand-held shooting at night.

What is the best aperture of the lens?

Many people think that the smaller the aperture of the lens, the higher the image quality; Others unilaterally pursue a large aperture, hoping to get a smaller depth of field (or greater blur). In fact, these two extremes are not correct. Generally speaking, the best state of lens imaging is when the maximum aperture value is reduced by 2-3 levels. For example, a lens with a maximum aperture of F2.8 has the best imaging quality when its aperture is close to F5.6-F8.

How to make photos clearer? What are the influencing factors?

Clarity is the most basic requirement of every photographic work (unless the photographer has a special idea). There are many factors that affect the clarity of the picture. Beginners often encounter several kinds:

Focus. When shooting still objects, you can use the single focus mode of the camera to fix the focus on the subject; If you shoot a moving object, you should turn on the camera's auto-tracking focus mode to keep the focus moving with the object.

Shutter. When shooting hand-held, try to increase the shutter speed and shorten the shutter exposure time. The faster the speed, the better the picture definition. If it is night shooting and it is difficult to improve the shutter speed, you should try to use a tripod to maintain the stability when shooting.

Depth of field is what we often say, blur can bring beautiful picture effect, but we should also pay attention to it. When taking a portrait, if the facial area outside the focus is blurred, it is counterproductive. Similarly, in macro shooting, if the subject only captures a local area because of excessive blur, it is not what we want. In landscape photography, we must ensure that "how far is it from our feet" is equally clear.

What is the RAW format? What are the benefits?

If you use a SLR or micro-camera for photography, but you haven't used the RAW format yet, it is highly recommended that you use the RAW format. RAW format file is the original file of digital photos, which records the most complete and abundant image information, while JPEG format is compressed by discarding some information in RAW file. The most powerful function of RAW format lies in the later stage. If the photos you take are too dark or too bright, the photos in RAW format can easily restore the photos to normal exposure. In addition, the RAW format can adjust the details of the picture by setting the saturation, contrast and sharpness to make the picture quality better. It should be noted that each manufacturer's RAW has different file name suffixes, such as Nikon's. Nef, Canon's CR2, .Cr3, Sony's. Arw, Panasonic's RW2 ... and so on.

What is surround sound exposure? What's the role?

Peripheral exposure is to take multiple photos of the same scene with different exposures, so that the photographer can choose the most suitable one, which is especially suitable for shooting in some scenes with complex lighting environment. The common method is to expose a photo at -0.3EV, 0EV and +0.3EV, and generally you can always get a photo with relatively uniform and accurate exposure. If you need more details, you can take one photo from -0.7EV, -0.3EV, 0EV, +0.3EV and +0.7EV, and finally get five or more photos with different exposures. General SLR cameras or micro-cameras have their own peripheral exposure function. Just select the corresponding function and set the number of exposure sheets, which is very simple.

What is gate b? What's the use?

Some high-end digital cameras will have a B option on the mode dial, which is the B door. Gate B means that the shutter time is completely controlled by the photographer, and the photographer needs to press the shutter twice to complete the whole shooting process: 1 press the shutter for the first time to open the camera lens and start shooting until the shutter is closed for the second time to complete shooting. The "click" process, which was originally completed instantly, is freely decided by the photographer in the B-door mode.

The biggest function of door B is to allow you to be exposed for a long time and get many professional and beautiful pictures. For example, the traffic at night, such as silky running water, floating clouds in the sky, atomized sea surface, star shift and graffiti. . Wait a minute. In the process of using door B, it is best to use tripod and cable release.

When is the best time to shoot at night?

The most important factor in shooting city night scenes-shooting time. The best time to shoot a city night scene is when it is getting dark, not after dark. Choosing blue to darken the sky, with the warm light when the lights are on, is far more beautiful and easier to shoot than when the sky is completely dark.

However, this is precisely the main mistake most people make when shooting city night scenes. If you don't believe me, we can search the night view of the city taken by professional photographers online. Almost none of them were taken in the dark.

How to shoot the effect of outstanding stars?

The starlight effect needs to meet two basic conditions:

1) point source. Point light source is based on the luminous area, which is related to the shooting distance: standing under the street lamp, the street lamp distance is short, the luminous area is large, and it is impossible to form a point light source. But if you look at it from 100 meters away, the street lamp will be reduced to a point and become a point light source.

2) split. The path gap of light passing through the lens is too large, so the aperture should be narrowed to form a narrow enough gap to force the light to diffract. In order to produce a star-studded effect, photographers need to use a small aperture for exposure. The smaller the aperture, the more obvious the effect.

What are the characteristics of smoothness? How to use it?

Advantages: bright colors.

Smooth lighting softens the colors in the picture and can better express colors. In the sunlight environment, because the scene directly receives sunlight, it is not easy to be disturbed by the color temperature change and other colors, and the color saturation is good, so it is easy to get a bright picture. Therefore, it is suitable for shooting scenes with color as the main performance focus.

Disadvantages: lack of shaping

The sunlight is flat and the front of the scene is bright, but there are few shadows in the picture. Therefore, the distinction between light and dark is not obvious, which will make the subject and background, subject and companion lack distinction and three-dimensional sense, and it is difficult to shape the appearance of the scene. Therefore, the picture taken along the light mainly depends on the brightness difference, color contrast and line relationship of the subject.

What are the characteristics of sidelight? How to use it?

Advantages-rich layers and strong three-dimensional sense

Side light can produce a very directional projection, which can well show the appearance, texture, three-dimensional sense and depth of the subject, and has a very good modeling effect. Another advantage of sidelight is its flexible direction. According to the degree of deviation, it can be divided into front light, front light and backlight, showing different effects.

Disadvantages: If it is color film, some colors will be blocked by shadows, so you have to consider and choose when shooting. Therefore, sidelight is more suitable for expressing structure, texture and texture, and color is not the main factor.

What are the characteristics of backlight? How to use it?

Advantage-contour modeling

Backlight is the most unique light in landscape photography, and the part of the scenery illuminated by light will produce a clear outline, which is obviously separated from the background, giving people a clear artistic sense. At the same time, it can also produce all kinds of silhouette light and transparency, giving people a sense of holiness and clarity.

Disadvantages-difficult to control and easy to die.

Shooting can suddenly bring good artistic effects, but at the same time it also puts forward higher requirements for photographers' skills. We should fully grasp the intensity and angle of backlight and fill the light in time, otherwise it will be a terrible picture.
