Hi steemiants .
Tonight I discuss the explanation of what a photographer is
Photography (from English: photography, which comes from the Greek word "photos": Light and "Graph": Paint / write) is the process of painting / writing using light media. As a general term, photography means a process or method for generating images or photographs of an object by recording the reflection of light that objects to it on a light-sensitive medium. The most popular tool to capture this light is the camera. Without light, no photo can be made.
The principle of photography is to focus light with the aid of refraction so as to burn the light catcher medium. Medium that has been burned with the right luminous light size will produce an image identical to the light entering the refracting medium (hereinafter referred to as the lens).
To generate the right light intensity to produce the image, used the aid of a measuring instrument in the form of a lightmeter. After getting the correct lighting size, a photographer can adjust the intensity of the light by changing the combination of ISO / ASA (ISO Speed), diaphragm (Aperture), and speed (speed). The combination of ISO, Diaphragm & Speed is referred to as exposure.
In the era of digital photography where films were not used, the film speed that was originally used developed into Digital ISO.
Photography has now grown into a lifestyle, it started since the advent of the digital age and the development of social media.
This is all I can explain about photography hopefully useful for and
Thank you
