What are large aperture, shutter speed, slow door, high-speed shutter, wide angle, flash and flash bounce, backlight, one-tenth exposure, polarizer and strong light?

Large aperture: there is a number behind f, the smaller the number, the larger the aperture; A large aperture can speed up the shutter speed and make the depth of field shallow.

Shutter speed: 1/ digital seconds, which represents the length of a shutter.

Slow door: refers to slowing down the shutter speed.

High-speed shutter: improve shutter speed.

Wide angle: the focal length is less than 35, which is generally called wide angle.

Flash: Some cameras have built-in flash and external flash. Generally speaking, the external flash is more powerful and flexible to use.

Flash rebound: it should refer to flash jump, which can only be realized by external flash. When flashing, you don't flash directly at the subject, but flash through the ceiling and wall lamp, making use of the diffuse reflection of light to make the light uniform and soft.

Backlight: the camera shoots at the light source, and the subject is between the camera and the light source.

Polarizer: a filter used to partially eliminate reflection and make the sky bluer.

Glare: A light that can cause a heavy shadow on an object.
