What aspects should novice photographers improve their photography skills?

This little knowledge is very important for digital photography. Such as "ISO adjustment" and "exposure compensation" are very special and important. I have introduced "ISO adjustment" before, so let's get to the point.

Concept of exposure compensation (EV): Photography is actually a process in which a photographer uses his own photography technology to calculate the ambient light and capture the scene image through photographic equipment. This process is related to the aperture value of the device (controlling the luminous flux entering the camera per unit time), shutter speed (exposure time) and ISO (sensitivity to light). Nowadays, traditional devices and DC will calculate the ambient light through their own internal programs, and automatically adjust the aperture, shutter and even ISO value. However, in the Gao Fancha environment with complex light and strong contrast, the photos taken by P (programmed automatic exposure) blocks are often unsatisfactory and the effect is not the best. At this time, the photographer needs to manually adjust the exposure parameters of the equipment, that is, the exposure compensation EV (exposure value).

There are many ways to compensate and adjust the light, such as flash lamp, photographic lamp and reflector. Adjustment of aperture value and compensation of luminous flux parameters for exposure time. Strictly speaking, the above compensation methods should be classified as the concept of "light compensation or exposure control". There is also the adjustment and compensation of EV unique to digital cameras.

The compensation of external light by flash lamp is hard in the absence of other supplementary light sources, which often leaves obvious shadows on the background of the subject, and at the same time makes the highly reflective part of the subject lose its sense of hierarchy and has serious distortion, so it is rarely used.

Photographic lighting can create a good shooting effect, but it is often limited to the studio due to the limitations of conditions.

Reflective plates with soft light and supplementary light effect are widely used in portrait photography in small scenes, mostly for supplementary light on the main face, and their limitations are self-evident. The adjustment of aperture and shutter luminous flux parameters is often due to the need to consider the influence of depth of field and moving objects in the shooting process, which will have a feeling of being stretched in practical application.

For popular digital cameras, the most common method is to adjust EV to achieve the purpose of exposure compensation.

The adjustment range of most consumer digital cameras is 2.0EV, and the high-grade DC can reach 3.0EV. One of the indicators to test a DC is its manual adjustment function, and the adjustment accuracy is also an important factor in EV adjustment, generally 0.3 or 0.5. The smaller the grade difference, the more satisfying the photographer's creative intention.

For beginners, exposure compensation is generally used for still life and scene shooting. This situation is suitable for you to adjust the parameters calmly, shoot many films with different compensation values, and choose the best works from them.

Correctly adjust the EV value: use EV+ in typical underexposed scenes (objects have many bright areas, such as water surface, snow scene, sunrise and sunset scene, etc.). ), and use EV- in typical overexposed scenes (dark areas with many objects, such as dense forests, shadows and close-ups of black objects, etc.). ). Simply put, it is "white plus black minus, bright plus dark minus".

It should be noted that the aperture/shutter parameters of the camera will change when the EV value is adjusted, regardless of whether the DC is in the P file or the S/A file: when the EV is adjusted in the P file, the aperture and shutter of the camera will be automatically adjusted; The fixed aperture under the adjustment of block A and EV will change the shutter speed; When the shutter is fixed under the S-stop and the EV adjustment is linked, the aperture size will change. However, these changes of aperture and shutter will not affect the exposure compensation effect after final imaging.

If you master the adjustment of ISO and exposure compensation, then the digital camera will be more handy to use. After playing with the digital camera, take a look if you take pictures.

Introduction skills of photography

Photography is actually a complicated and simple thing. If you master the essence, it will be easier. First of all, introduce composition. Composition is the first and most important step to take a good photo.

1. light processing

The dynamic characteristics of camera light are not only determined by the technical requirements and modeling characteristics of camera shooting, but also closely related to the different requirements of different content for light. In documentary images, such as documentaries, scenery films, documentary feature films, etc. Usually, it is required to reproduce the typical light effects in the typical environment without distortion, pay attention to the use of light in real life, and emphasize the real and natural light effects. However, the light consumption of artistic images is more complicated and diverse than that of documentaries, which can be handled manually as needed, but it should be properly mastered according to the different shooting contents and program genres.

2. Color processing

Color can affect our mood, for example, shooting red can make people feel happy and unrestrained, green can make people feel quiet and peaceful, and white can make people feel terror and death. When shooting, according to the needs of the theme and content, choose colors with distinctive emotional characteristics and clear relationships, and match, combine and use them appropriately and flexibly.

Colors can also be used to express time. For example, red leaves symbolize autumn, orange grass tells us that the sun sets, while colorful flowers show the morning. Colors can also set off the expressive force of visual elements, such as rosy skin to express youth.

3. It is very important to deal with the shading in image composition. When we choose the subject in the picture, putting a small shadow tone in a large area of bright shadow tone or appearing a small bright shadow tone in a large area can attract the audience's visual attention and help to express the object or subject to be emphasized. The arrangement of light and shade can also be used to balance the composition of the picture. If one side of the picture is very dark and the other side is very bright, properly adjusting the relationship between light and shade by composition can change this unbalanced situation and make the structural form of the picture stable and balanced.

4. Line processing

In composition, the beauty of lines depends largely on their relationship with the frame of the picture. For example, shooting the same flagpole, although it is upright in real life, it can occupy the center of the picture in the picture frame of the TV screen, or it can cut the picture beside it, giving people a different feeling. This requires you to know and choose the best line form of the subject, which can best express and embody its essence, and best convey the theme and creative intention in the shooting process.

After mastering the composition, I think you are only a little bit away from success. Don't worry. Finally, let's take a look at the main points we summarized. I believe that as long as you take more photos and think more, you can create excellent photos.
