2. The smaller the aperture value marked on the camera, the larger the aperture. ㈤
3. The shutter time of1125 seconds is twice that of 1/250 seconds. (10)
4. The aperture f2 is 64 times larger than f 16. (10)
5. When the focal length and shooting distance of the lens are the same, the smaller the aperture, the greater the depth of field. ㈤
6. The first photograph in the world photography history was taken by Nipps in 1826. ㈤
7. The optimal shutter time for subsequent photography is longer than 1/30 seconds. ㈤
8. At present, the two famous brands of domestic cameras are Phoenix and Seagull. ㈤
9. When red light shines on yellow flowers, they will appear red. (10)
10. The longer the focal length, the smaller the viewing angle of the lens. ㈤
1. The function of the aperture is only to control the luminous flux. (10)
The aperture in the lens has three functions:
1. Determines the amount of light passing through. The larger the aperture, the more light enters; The smaller the aperture, the less light enters.
2. The aperture size also determines the depth of field. The larger the aperture, the smaller the depth of field; The smaller the aperture, the greater the depth of field.
3. Aperture is also used to control aberration. Usually, the smaller the aperture, the better the focusing effect of the image.
2. The smaller the aperture value marked on the camera, the larger the aperture. ㈤
The numbers on the lens, such as1.4,2,2.8,4,5.6, represent the aperture number. The smaller the number, the larger the aperture, which is inversely proportional. For example, if F4 is larger than F5.6, the larger the aperture, the larger the aperture and the more luminous flux.
5. When the focal length and shooting distance of the lens are the same, the smaller the aperture, the greater the depth of field. ㈤
When the focal length of the lens is the same and the shooting distance is the same, the smaller the aperture, the larger the depth of field range; The larger the aperture, the smaller the depth of field.
6. The first photograph in the world photography history was taken by Nipps in 1826.
The first photographic work in the world was taken by French soldier N.J. Nipps (1763- 1833) in 1826. The scenery outside the window.
