Today, I will take a novice photographer with six tips in the shooting process to teach you the setting of camera parameters and the skills you need to pay attention to. Many people think that taking pictures can be achieved with one click. In fact, good photos can only be taken after a series of preparations such as framing, ranging, focusing and shutter, and the photos taken after post-processing will be better. Next, let's take a look at some practical shooting techniques with me!
First, the aperture
Aperture is a commonly used parameter in shooting, and its size can directly affect the amount of light entering and the depth of field, so it is very important to control the aperture when shooting. The representation of the aperture is generally expressed by F. The greater the value of F, the larger the aperture and the more light the lens gets. In short, the bigger the aperture, the brighter the picture will be. The relationship between aperture and depth of field is that the larger the aperture, the smaller the depth of field, and the smaller the aperture, the greater the depth of field.
When shooting, the adjustment of aperture size will affect the quality and presentation effect of the picture. If a small aperture of F 16 is used, the object and the subject can be as clear as the background. When taking landscape photos, you can narrow the aperture to a certain range, such as F8-F 16, which can present a clear picture texture as a whole. By adjusting the aperture, the virtual reality and layering of photos can be adjusted. When shooting still life and figures, you can blur the background appropriately to make the people more dreamy and real.
When adjusting the aperture, you should manually define the size. In shooting, Xiao Bai can highlight the main characteristics and behaviors of the characters as long as he understands that they are shot with large aperture and long focal length. Use a smaller aperture when shooting scenery, so that the greater the depth of field, the better the effect. You can practice a fixed still life or scenery repeatedly when you are a beginner.
Second, the shutter
Another important parameter that beginners need to learn is the adjustment of shutter. Shutter speed is closely related to exposure time. If the light is good and sufficient when shooting, the exposure time is short and the shutter speed is short. For beginners, you can choose the automatic file or the P file on the camera. These two gears are relatively easy to operate and don't require users to make too many adjustments. At the same time, the amount of light entering the photo can be adjusted, and the shutter can be adjusted empirically according to the environment and light effect when shooting.
Many scenes using shutters are used to shoot moving objects. If you find that the picture is blurred and the moving object is in a ball, there must be something wrong with your shutter speed. It is very important to adjust the shutter speed when shooting moving objects. If we can't control the relationship well, the picture will be either static or fuzzy. Shutter speed can only be defined after years of accumulation. For example, the shutter speed can be kept at1125 seconds when shooting a moving pedestrian, and it needs 1/65438+ when dripping water. There are certain rules to follow.
Third, the macro.
Macro shooting, as its name implies, is the main body of shooting small objects, such as small insects and food details. Macro shooting needs to make good use of light and shadow changes and composition skills. The definition of macro shooting is a key issue. If the photo is blurred, it will definitely not work. Micro-photography mainly describes the details vividly. Therefore, a tripod should be used as an assistant when shooting, because people tend to shake their hands when holding it. I always feel blurred when I enlarge it. With a tripod, you can fix the camera in a certain position, focus on the micro-world accurately, and ensure the clarity of the photos.
In fact, many cameras are equipped with macro lenses. Although its price is relatively high, it is not suitable for beginners, but the effect is very good. In fact, you can also take macro photos with a zoom lens and adjust them into macro files, which is flexible and convenient to use. When taking macro photos, you should avoid using too bright light, which is easy to produce various shadows. When the light effect is dim, you can supplement the light appropriately to coordinate the overall effect, and at the same time, you should present more details, ensure a reasonable camera ISO, and use the focal plane to learn what beginners in Yonghe City need.
Fourth, sensitivity.
Sensitivity is actually what we call ISO. People who have studied photography must know that aperture, shutter and sensitivity are called the three elements of exposure. Sensitivity refers to the camera's sensitivity to light. In traditional cameras, the setting of sensitivity is a fixed value and cannot be changed. Changes over the years will also change sensitivity. The higher the sensitivity, the stronger the sensitivity to light. Shooting in a dark environment can improve the ISO value, thus making the photos brighter and more noisy.
Sensitivity is particularly important when shooting at night. We can see from different photos that the higher the ISO sensitivity, the higher the brightness of the picture. Adjust ISO moderately when shooting, but it may explode if it is adjusted too high. If the light is insufficient and the ISO value is too low, darker photos will be taken. At the same time, the noise will increase after the sensitivity is improved, and the photos will be unclear. It is important to adjust the sensitivity when taking pictures.
Verb (abbreviation for verb) focal length
In addition to controlling the aperture, the focal length is also an important parameter that needs to be manually adjusted when shooting. Simply put, the focal length determines our field of vision and viewing area from the lens. From the parameters on the lens, we can see the focal length mark, such as 50mm, 17-40mm, etc. These two focal length marks represent different meanings. The number of 50mm represents a fixed focal length, and the focal length is fixed, while the logo between the two numbers identifies the zoom lens.
When using focal length, you only need to remember one core content. The smaller the focal length, the wider the field of view, the larger the framing range, and the more photos taken, the smaller the proportion of each scene in the picture. For example, taking a landscape photo can capture the whole scene with a small focal length, and the field of vision covers the whole mountain peak, but the details such as trees on the mountain are very small. If the focal length becomes larger, you can see more details. Focal length is often used for ultra-wide angle shooting, landscape shooting and so on.
Sixth, exposure
Camera exposure refers to the amount of light that the lens enters the photosensitive element when shooting. A high-definition, rich and natural photo must be exposed normally. If the exposure is insufficient, the light received by the photosensitive element will be less, and the overall picture will be dark. If it is overexposed, it receives too much light and the photos are too bright. Reasonable exposure is formed by the comprehensive action of aperture, shutter and sensitivity. Only the close cooperation and contact of the three can ensure the normal exposure during shooting. When the light of the photosensitive element is insufficient, we can adjust the exposure by opening the aperture or reducing the shutter speed.
As the three elements of exposure, any parameter setting of aperture, shutter and sensitivity can determine the final imaging effect. As a beginner, first of all, we should study and study theoretical knowledge in depth and improve our practical ability through actual shooting. You can use P file and automatic file to shoot, which is suitable for novices and users who don't like to set up cameras. In this mode, various configurations of the camera environment can be automatically adjusted without manual exposure by the user.
The above six skills are several elements and configurations that beginners must learn when taking pictures. In any case, taking photos with digital cameras and SLR cameras requires more practice, more study and more observation. Only by learning the basics can we take a more advanced picture and make a technical control.
