Teach you to truly understand the three elements of photography: aperture, shutter and iso.

1. Definition: A component that controls the amount of light entering the camera and the depth of field.

The camera is a darkroom, and the aperture is a window to control the light entering the darkroom.

* The numerical value is represented by f, and the smaller the numerical value, the larger the aperture, the more light entering and the larger the picture. ?

2. Depth of field

Large aperture, shallow depth of field-(blurred background)

Small aperture, deep depth of field-(solid color background)

* Large aperture is suitable for portraits and small aperture is suitable for landscapes.

3. What aperture is used?

Choice of depth of field: shallow depth of field with large aperture and deep depth with small aperture.

Hand-held or tripod, hand-held: the shutter should not be lower than the safety shutter (it is faster and more difficult to take a fake shot by increasing the aperture shutter)

Whether the scene moves, moving: increase the shutter speed and increase the aperture.

Whether the light is sufficient: large aperture or small aperture is ok. The premise of using a large aperture is that the shutter will not exceed the range of the fastest shutter of the camera (1/4000s or 1/8000s).

Second, the shutter

Definition: The main function of shutter is to control exposure and "freeze" moving images. The slower the shutter speed, the greater the exposure, and the faster the shutter speed, the smaller the exposure.

The faster the shutter is, the more you can grasp the instantaneous static state of the moving object. If you want the scene to achieve the expected image, you must rely on the close cooperation of aperture and shutter speed.

Shutter and high-speed shutter: 1/4000s

Low speed shutter: 4 seconds

B shutter: control your own cable release.

Three. Iso (light sensitivity)

Definition: The higher the iso, the more sensitive the photosensitive element and the brighter the picture.

* It is not recommended to set iso too high, because there will be noise in the picture.

Low iso shooting

The scene is bright and the model's face is smooth. In order to prevent overexposure, low iso shooting is adopted. For example, manual exposure F 1.8? 1/3200s？ iso 100

High iso shooting

The indoor scene is dimly lit and the model is backlit. In order to get a bright picture, high iso shooting is adopted in the safety shutter. For example, F 1.8? 1/80 later? iso800

In order to get a bright picture, high iso shooting is adopted in the security shutter because the scene is dim at night and matched with the lighting. Like what? F 1.6？ 1/ 100s？ iso 1800？

Tips: iso general mode will adopt "automatic".

Take more actual shots, think more and press the shutter.
