Introduction of p, s and m. The gears of SLR cameras and how beginners can take good photos.

Take 800D as an example, honey tea will explain to you what different models are used for.

First, fully automatic mode.

In the fully automatic mode as shown in figure 1, all parameters such as aperture, shutter and ISO cannot be adjusted. To put it bluntly, it is a fool mode, which is automatically completed by the camera. For people who don't like trouble, this model is very practical. But for those who like to learn photography, this mode is too restrictive to set anything.

Second, P program automatic mode

P mode is more advanced than automatic mode. This mode can adjust ISO, metering mode, etc. The camera can automatically adjust the appropriate aperture and shutter combination according to the environment. As shown in Figure 2, the P mode is displayed on the dial, and Figure 3 is displayed on the display screen.

In P mode, ISO can be set to avoid too much noise caused by high ISO.

There is a slight advantage over automatic mode when shooting night scenes, as shown in Figure 4.

Third, the aperture priority mode

In this mode, the camera can adjust the aperture, ISO and other parameters, and the shutter time is automatically adjusted by the camera according to the environment to ensure that the photos taken are normal. Fig. 5 is the sign of AV mode on the turntable, and fig. 6 is the display on the display screen.

If you want to achieve the desired effect by adjusting the aperture, you can choose AV mode. For example, if you want the background blur effect shown in Figure 7 or the night spot effect shown in Figure 8, you can shoot with a large aperture.

If you want to shoot the scenery, you can use the aperture of F8-F 1 1 to ensure the whole picture is clear, as shown in Figure 9.

Fourth, the shutter priority mode

In this mode, parameters such as shutter and ISO can be adjusted, and the aperture is automatically adjusted by the camera according to the environment to ensure the normal light and shade of the photos taken.

As shown in figure 10, TV mode is displayed on the turntable, and figure 1 1 is displayed on the display screen.

If you want to achieve some desired effect by adjusting the shutter time, you can choose TV mode, such as:

① People who want to capture the action can set the high-speed shutter time and take 12, the moment when people jump.

(2) If you want to shoot the slow door of the sea or the track of a car, you need to set a slow shutter, and you can use TV mode. The effect is shown in figure 13- figure 14.

Five, full manual mode

In the mode of Figure 15, we can set all the parameters such as aperture, shutter and ISO by ourselves. If the parameters are not adjusted correctly, the photos will be too bright or too dark.

So how to achieve normal light and shade in M mode? There is an exposure indicator in the viewfinder of the SLR, as shown in the box of figure 16, and the effect displayed on the screen is shown in figure 17.

When we adjust the aperture, shutter, ISO and other parameters, the scale will wander around "0".

When the scale is "to the left of 0" (negative number), it means that the exposure is insufficient and the photos taken are dark;

When the scale is "0 to the right" (positive number), it means overexposure and the photos taken are bright;

When the ruler is in the "0" position, it means that the exposure is normal and the photos taken are in proper light and shade.

In addition to these modes, there are other modes, such as portrait, landscape, macro, sports and so on. These modes are also fully automatic. Set the turntable to the corresponding mode if you want to shoot which type. To put it bluntly, it is a fully automatic mode with "professionalism". Honey tea is just a brief introduction.

① Portrait mode

As shown in figure 18, it is the symbol of portrait mode on the turntable. When shooting a portrait, the camera will automatically adjust to a large aperture to shoot a blurred background to highlight the person.

② Landscape pattern

As shown in figure 19, it is the sign of landscape mode on the turntable. When shooting scenery, the camera will automatically adopt a small aperture to make the whole photo clear.

③ Macro mode

Fig. 20 is a sign of macro mode on the turntable. When shooting small objects such as flowers at close range, the camera will automatically set the aperture, shutter and ISO.

④ Motion mode

As shown in figure 2 1, it is the symbol of motion mode on the turntable. When shooting a moving object, the camera will automatically increase the shutter speed to capture it.

At this point, honey tea has explained different patterns. I believe that after reading it, everyone will choose the appropriate mode according to different shooting scenes and take good photos.
