Difference between M, TV, AV and P files of SLR digital camera

1.m: Full manual mode, that is, the aperture size and shutter speed should be set manually, which is generally used by experienced photographers or people holding photometers.

2. TV: shutter priority, that is, you set the shutter speed first (for example, 1/50S), and the camera will choose the aperture size according to the shooting scene.

3.AV: Aperture takes precedence. Contrary to the above, now manually set the aperture size (such as 4.0), and then the camera automatically adjusts the shutter speed.

4.p: Both the aperture and shutter are obtained after the camera automatically measures light, and manual setting is not required, which belongs to the legendary fool mode and is more suitable for novices.

Key points of taking photos with SLR digital camera;

1, aperture is preferred when shooting portraits and landscapes. Aperture priority is to manually define the aperture size, and the camera will decide the shutter speed according to this aperture value. Because the aperture directly affects the depth of field, this mode is most widely used in ordinary shooting.

When taking portraits, I usually blur the background with a large aperture and a long focal length to get a shallow depth of field, which can highlight the subject. At the same time, a larger aperture can also obtain a faster shutter value, thus improving the stability of hand-held shooting.

When shooting scenery, I often use a smaller aperture, so that the depth of field is wider, which can make the distant and nearby scenery clear. This is also applicable when shooting at night.

2 shutter aspect:

Shutter priority is mostly used to shoot moving objects, such as sports, moving vehicles, waterfalls, flying objects, fireworks, water droplets and so on. Contrary to aperture priority, shutter priority is to obtain aperture value through camera metering when the shutter is defined manually.

Shutter priority is mostly used to shoot moving objects, especially sports shooting. Many friends find that when shooting moving objects, the subject is often blurred, mostly because the shutter speed is not fast enough.

In this case, you can use the shutter priority mode, roughly determine a shutter value, and then shoot. And the operation of the object is generally regular, then the shutter value can also be roughly estimated.
