What do scattered light, aperture, speed, lens and telephoto lens mean in photography?

Compared with direct light, outdoor, sunny days are direct light, the subject is direct light, and cloudy days are scattered light.

Indoor, the direct object of spotlight is direct light, which can be changed into scattered light by soft box or sulfuric acid paper, and the reflected light is generally scattered light.

Scattered light is also called soft light, and direct light is called strong light. Strong light is used to describe the outline of the subject, with obvious transition between light and shade, soft light and no obvious shadow.

Aperture means that the lens has a bright aperture. The larger the aperture, the smaller the aperture. At the same time, the aperture can also control the clear range of the subject, that is, depth of field, focal length and shooting distance.

Speed? It should be the shutter, indicating the shooting time, and 60 stands for 1/60 seconds. Shutter and aperture cooperate to achieve correct lighting and avoid overexposure or underexposure. Generally, when shooting with a camera in hand, the shutter speed should not be greater than the reciprocal of the focal length, for example, the focal length is 60, preferably within 1/60 seconds. Of course, according to personal circumstances, 1/8 seconds through exercise is normal.

Lens: I'm dizzy ... I'll check it myself.
