In order to adjust the shutter speed, we must turn a wheel next to the camera shutter release button and turn it left and right to adjust the shutter speed.
When we turn the wheel with our right index finger, pay attention to the camera information screen and find out the field of shutter speed to see if the shutter speed has changed when we turn the wheel. As shown in the above figure, we can see that the shutter speed is 1/200s at this time. You can try to practice by turning the shutter.
Av aperture priority
Turn the shooting mode dial on the camera body to Av and aim at the white sign next to it, that is, start the AV aperture priority shooting mode. This mode allows us to freely adjust the aperture size, while the rest, such as brightness and ISO, are handled by the camera for us.
Similarly, you can adjust the aperture value by pulling the wheel next to the shutter key and turning it left and right.
At this time, move the wheel with your index finger and pay attention to the F value on the camera information panel, as shown in Figure F3.5 above, which is the aperture value at that time. As the wheel rotates, this aperture value will change constantly.
Aperture size not only affects the difference of incoming light, but also mainly affects the depth of field. It is recommended to shoot still life. Through the different aperture sizes of large aperture (such as F 1.8) and small aperture (such as F8.0), feel the application of aperture size in shooting creativity.
Aperture is a device used to control the amount of light entering the photosensitive surface of the fuselage through the lens. Usually in the camera. We use the f value to represent the aperture size.
For the manufactured lens, we can't change the diameter of the lens at will, but we can control the luminous flux of the lens by adding a polygon or circular aperture grating with variable area inside the lens. This device is called an aperture.
Shutter is the English name of shutter. Shutter is a device used in camera equipment to control the time when light irradiates the photosensitive element. In addition, shutter Shutter was launched by China Education and Research Computer Network (CERNET), relying on CERNET's rich network resources, marketing and channel foundation.
Provide China college students with a variety of network services, such as VoIP, IM instant messaging, online movie music, genuine software, career counseling, etc.
Shutter points can be exchanged for all domestic calls, and you can call fixed landlines, mobile phones and PHS online. But at present, only the revised education network is supported. Confinement is also an American horror movie released in 2008.
