Popular Science Post: Do you understand all these functions on the camera?
straight to the point, this is a popular science article, written for users who are new to photography or even cameras. The camera is different from the mobile phone. The operation functions on the camera are very rich, but many functions are like a book for novices. In fact, the author a few years ago is also the same. Today, we will answer your questions.
1, single shot, high-speed continuous shooting, 10s remote control, 2s remote control
single shot, high-speed continuous shooting, 10s remote control, 2s remote control, this option is available on almost any camera, but for novices, you generally only use the default single shooting mode.
A single photo is to press the shutter once to take a photo, just like a mobile phone.
High-speed continuous shooting is used to shoot fast-moving objects, such as sports Competition, speed, roller skating, etc. If you are shooting in a dark environment, in order to ensure the success rate, you can also try high-speed continuous shooting. The speed of continuous shooting depends on the design of the camera, some cameras are 8 frames per second, and some cameras can reach 20 frames per second.
10s remote control and 2s remote control have the same meaning, that is, 10 seconds and 2 seconds countdown. When shooting some long exposure operations, the countdown time period can help eliminate camera shake. Or when taking a group photo, the countdown can leave time for the person who presses the shutter to run past.
2, 30s exposure and bulb
General cameras, the built-in shutter speed is mostly 1/4000 seconds to 30 seconds, professional cameras can reach 1/8000 seconds to 30 seconds . That is to say, the built-in shutter of a general camera can expose for up to 30 seconds, which is used to shoot night scenes, traffic, stars, milky way, etc.
Of course, many people need to shoot better subjects, such as stars If you need more than 30 seconds of exposure time, you can choose Bulb. Bulb is to press the shutter to start exposure, and release the shutter to end exposure. Since the camera shakes when you really press the shutter with your hands and do not loosen the meeting, the door B will generally be operated with a shutter release.
3, tracking focus, area focus, single-point focus
tracking focus, as the name implies, focus will dynamically track the focus according to the movement of the object, usually with high-speed continuous shooting. This situation is suitable for shooting moving objects, such as pets, children, racing cars, athletes, etc.
Area focus, usually in an area selected by the camera , Let the camera decide where to focus. This method is mainly for beginners and beginners in photography. After all, you don’t necessarily know what to focus on every time, so let the machine help users choose the right focus.
Single-point focus is a single focus point to focus. For example, if your camera supports a 425-point focus area, you can choose any point as the focus point. Beginners can try this mode to practice taking pictures.
4, spot metering, central metering, evaluative metering
spot metering, which is mainly used in a photographic environment that meets the requirements for accurate exposure of a certain subtle place For example, if I want to ensure that the exposure of a certain tile on a wall is accurate, I can choose spot metering and place the focus point on the tile’s corresponding position.
Central metering, mainly to meet the requirements of accurate exposure in an area Photography environment. For example, when you take a group photo and require accurate exposure of a girl’s face, you can use this metering mode.
Evaluative metering is also the most common mode of use. More than 90% of users use this mode. This mode is to let the camera automatically determine the light of the entire environment, and then perform metering and shooting. For newcomers, we recommend that you start using this mode first.
5. Interval timer
Interval timer is not available in every camera. If the camera has this function, you can try to shoot some very good photographic works, such as stack synthesis Of star trails.
For example, when we take photos of star trails, the material we need to stack is About 100 shots, one shot every 10 seconds, one exposure 5 seconds, we can’t stand there holding a stopwatch and waiting for the shutter. The interval timer can replace this job, and the timing is accurate. The camera helps you to complete all the operations, what a lighthearted thing.
Of course, the camera still has many functions, we will not introduce them one by one because of limited space. If you really don’t understand, you can refer to the manual to study. Just like photography, the more you understand the functions of the camera, the more helpful it is for photography. Of course, during this special period, it is recommended that you shoot some still lifes at home instead of going out to practice photography.
