What do the camera parameter letters stand for?

Camera parameter letters: F stands for aperture and ISO stands for sensitivity.

1, f stands for aperture: controls the amount of light entering the lens, and the number after the letter "f" is the aperture value. Among them, the smaller the number, the larger the aperture, the more light the lens enters, the brighter the picture, the shallower the depth of field and the more blurred the background.

2.ISO stands for sensitivity: ISO. The higher the ISO, the more light can be captured. At the same time, the higher the ISO, the more noise there is in the photo, and other conditions remain unchanged. ISO is controlled below 800, and the picture quality is good. It is best to use 100 ISO during the day.

3. A camera is a device that records the image of a photographed object on a photoreceptor or a storage medium through a lens, and it is a general term for instruments with lens imaging function. 1839, Daguerre, France made the first practical silver camera, which was exhibited at the joint meeting of French Academy of Sciences and French Academy of Arts in August 19. Daguerre camera is mainly composed of lens, aperture, shutter, viewfinder and cassette. 1839, after the invention of Daguerre camera was announced, was also called the birth year of photography technology, so Daguerre was called "the father of photography" by later generations. With the continuous development of camera technology, the application of cameras can cover advertising, news, printing and many other fields.
