What does a by mean in the picture?

The author of the photo refers to the author of the photo. There are two situations.

First, refers to the photographer: photographers usually handle or modify their own photos, even if they ask others to handle the proofreading on their behalf, they will definitely write the name of the proofreader.

Second, refers to the modifier: PS lovers often take photos taken by others and use some of them as material to make their own special effects pictures. The produced picture has nothing to do with the original picture, and the production process has completely become two different types or effects. It takes a certain amount of time and energy to complete this situation, and the name of the photographer will be replaced by the name of the person whose photo has been modified, because this picture has completely become another picture.

The protagonists of the extended data camera are the photographer, the subject and the camera equipment, focusing on the subject and recording the picture on the camera equipment. The operation process of taking pictures is divided into: distant view, panoramic view, middle view, close view, close-up and microscope. Photography skills include the use of lenses-pushing, pulling, shaking, moving and following, and the combination of lenses-fading out, fading in, switching and overlapping. In the wide-angle stage of framing and the telephoto stage of the left picture, and when changing the focal length of the lens or moving the camera position, the lens holder is always aimed at the subject to shoot.

Photography, also known as photography, generally refers to the process of exposing the photosensitive medium through the light reflected by the object, usually using a mechanical camera or a digital camera. With the popularity of smart phones, it has become more popular to take photos of life with mobile phones.

Photography is to use a video camera (video shooting equipment) to convert optical image signals into electrical signals for storage or transmission. When we shoot an object, the light reflected by the object is collected by the camera lens and focused on the light receiving surface of the camera device (such as the target surface of the camera tube), and then the light is converted into electric energy by the camera device, and a "video signal" is obtained.
