What are the functions of several gears on the camera?

The gears SP, AUTO, P, S, A and M on the camera have different functions, which are explained in detail below.

1, automatic transmission mode

This is the stupid equipment of the camera. You just need to turn on the camera and press the shutter. This gear value is automatically set by the camera according to the surrounding environment. This gear is suitable for friends who have just started the camera. Using this gear is not a shameful thing, and sometimes it can bring us unexpected results.

2. Automatic exposure mode of P file program

The automatic exposure mode of P file program is a simple, fast and reliable way.

The specific method is: when shooting indoors in low light, the camera will automatically jump up and stand by (the same is true for automatic gear). If you want to shoot in pure natural light, you can turn off the flash, and it will automatically combine into "big aperture, fast speed" as much as possible to prevent the image from blurring at slow speed.

When shooting in outdoor strong light, it will combine a smaller aperture and a higher shutter speed, and you can turn on the built-in flash of the camera as the auxiliary light for people when shooting in backlight.

3.AV aperture priority mode

AV aperture priority mode is a gear mode with aperture priority, and other values will change automatically according to the change of aperture. This mode is also a combination of depth-of-field priority automatic exposure. When selecting AV files, the depth of field can be controlled by adjusting the aperture size to show the relationship between virtual and real works.

For example, if you want to take a landscape photo that doesn't need to be realistic or realistic, using a smaller aperture (F 1 1 or F 16 or above) can make all the scenes in the picture very clear and the image quality of the picture is also high. If it is necessary to highlight the subject and blur the background when shooting close-ups of portraits or other scenes, you can set a larger aperture to shoot.

As for the exposure control, there is no need to worry, because in the process of adjusting the aperture, it will automatically track and set the corresponding shutter speed with the change of the aperture size to ensure accurate exposure.

4. TV shutter priority mode

TV Shutter Priority Mode It is a gear mode that gives priority to the shutter, and other values will change automatically according to the change of aperture. We often encounter a problem when taking pictures, that is, moving objects are easy to blur. What is the reason?

5.M manual control mode

M-speed manual control mode is that the shutter speed and aperture size are manually adjusted, and the action is a bit complicated, which is not as convenient as P, AV and TV modes and is not easy to capture, so it is rarely used at present.

You only need to use a flash when shooting a backlit portrait in natural light, and you should accurately expose the natural environment as auxiliary light; Or shooting portraits under night light requires both proper exposure of the face and correct exposure of the night background. Therefore, it is necessary to consider the shutter speed of the appropriate aperture according to the flash index and the distance between people to achieve the best of both worlds.

This gear mode is commonly used by professional photographers, and it is also the most difficult mode to grasp, because you need to consider the aperture size and appropriate shutter speed, as well as white balance, color temperature, ISO and many other factors when shooting. This requires rich experience and continuous shooting training summary.
