Functions on the camera

Do you understand these functions on the camera?

  1. Single shot
  2. 30s exposure
  3. Tracking focus
  4. Spot metering
  5. Interval timer
Open the door, this is a popular science article for users who are new to photography and even new to camera . The camera is different from the mobile phone. The operation functions on the camera are very rich, but many functions are like novices to novices, in fact, I am the same a few years ago. Today, we will answer your doubts.

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 equipped on almost any camera, but for novices, we generally only use the default single-shot mode.
A single photo is just pressing the shutter button once to take a photo, just like a mobile phone.

High-speed continuous shooting is used to shoot fast-moving objects, such as sports competitions, speeding, roller skating and so on. If you are shooting in a dim environment, you can also try high-speed continuous shooting to ensure success. 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 period can help eliminate camera shake. Or when taking a group photo, the countdown can be left for the person who presses the shutter to run away.

2. 30s exposure and bulb

Most cameras have a built-in shutter speed of 1/4000 to 30 seconds, and professional cameras can reach 1/8000 to 30 seconds. That is, the general camera's built-in shutter can expose up to 30 seconds (TV or M operation is recommended), which is used to shoot night scenes, traffic, stars, the Milky Way, and so on.

Of course, many people need to shoot better subjects, such as star tracks, etc., which requires an exposure time of more than 30 seconds, and can choose bulb. The bulb is to press the shutter to start the exposure, and release the shutter to end the exposure. Since the shutter will be shaken when the shutter is really pressed by hand, generally the bulb will be operated with the shutter cable.

3. Tracking focus, area focus, single point focus

Tracking focus, as the name suggests, is that focus will dynamically track the focus according to the movement of the object, which is generally used with high-speed continuous shooting. This situation is suitable for shooting moving objects, such as pets, children, racing cars, athletes, and so on.

Area focus is generally in the area selected by a camera, letting the camera decide where to focus. This method is mainly used by beginners and beginners in photography. After all, everyone does not necessarily know what object should be focused on every time, so let the machine help users to choose the appropriate focusing object.

Single-point focusing is focusing on a single focus point. For example, if your camera supports a focus area of ​​425 points, you can choose any point as the focus point. Beginners can try this mode to practice taking pictures.

4. Spot metering, center metering, and evaluative metering

Spot metering is mainly used to meet the photography environment that requires accurate exposure to a subtle point. For example, I need to ensure the exposure of a tile in a wall is accurate. You can choose spot metering and focus At the position corresponding to the tile.

Central metering, which mainly meets the shooting environment for accurate exposure in an area. For example, when taking a group photo, the exposure of a girl's face is required to be accurate. You can use this metering mode.

Evaluative metering is also the most common mode of use, with more than 90% of users using this mode. This mode is to let the camera automatically judge the light of the entire environment, and then perform metering shooting. For newcomers, we recommend that you start with this mode.

5. Interval timer

The interval timer is not available for every camera. If the camera has this function, you can try to take some very good photographic works, such as star track photos that need to be synthesized.

For example, when we take photos of star trails, we need to stack about 100 materials, take one every 10 seconds, and take an exposure for 5 seconds. We cannot stand there holding the stopwatch and wait for the shutter. The interval timer can replace this task, and the timing is accurate. The camera helps you complete all the operations.

Of course, the camera also has a lot of functions, we will not introduce them one by one due to space limitations. If you really do not understand, you can refer to the manual to study. Just like photography, the more you understand the functions of a camera, the more useful 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.
