Camera photography introduction video

What are the skills of camera photography? Below, I have compiled an introductory video tutorial on camera photography and a description of photography ranking, hoping to help you!

Explanation of terms about camera

1, light ratio

Refers to the light reception ratio between the dark side and the bright side of the object under the illumination environment. The light ratio is of great significance to the contrast control of photos.

2. Brightness level

Refers to the specific position of lamps in three-dimensional space. Among them, there are surface lights, slap lights, platform pillar lights, foot lights, platform ceiling lights, ceiling lights gathering, ceiling lights flooding, sky lights, floor lights, side bridge lights, side lights, (hanging cage bench) chasing lights and so on.

3. focal length

Distance from the center of the lens to the focal point. It is also the distance from the center of the lens to the imaging plane such as the backplane or CCD in the camera.

4. Perspective

The angle between the lens center and the diagonal ends of the imaging plane is the lens angle. For the same imaging area, the shorter the focal length, the larger the viewing angle.

5. Lightness

The brightness of the lens is the amount of luminous flux. The larger the aperture, the greater the luminous flux and the smaller the brightness. Brightness is calculated as a multiple of the aperture coefficient. Brightness is one of the important factors that determine exposure.

6, three-dimensional sense

Through the processing of light, tone and color, the shape of the object is expressed in length, width and height, and then the main body in the three-dimensional space is reproduced on the plane to obtain the feeling of three-dimensional shape. Generally, side light and backlight are used for shooting.
