How to set a large aperture for the camera

It is recommended that the novice camera set the camera to be fully automatic. Friends who are familiar with camera operation should learn to set the camera aperture, sensitivity and shutter speed. Do you know how to set the aperture of the camera correctly? I hope my answer can help you.

1. If you want to use the maximum aperture of a large aperture fixed-focus lens, you should set f/ 1.4-f/2, which can effectively highlight the subject and blur the background.

2. If you want to use the maximum aperture of the standard zoom lens, you should set f/3.5-f/5.6, so as to shoot the dim scene of the street after dark.

3. If you want to shoot with a standard zoom lens in the daytime, you should set f/8-f/ 1 1, so as to keep the photos as clear as possible and get better picture quality.

4. If you want to get a large depth of field by macro photography, you should set f/ 16, which can shoot macro, effectively improve the sensitivity and increase the light input.

5. If you want to get super wide-angle starlight, you should set f/ 13-f/ 16, and you can look for obstructions or dark backgrounds near the point light source.

6. If you want to check the dirty spots of photosensitive elements, you should set f/22, so that you can find white walls.

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. In order to express the pore size, we use the value of F/.

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.
