Exposure:
Exposure refers to the "brightness of the photo". We need to adjust the parameters of the camera to control the exposure of the photo, mainly adjusting the shutter, aperture, sensitivity and exposure compensation.
EV:
EV is the exposure index of the camera. The exposure amount is combined by different shutters and apertures, and the exposure amount achieved by different combinations is the same.
Color temperature:
The color temperature is generally expressed in K. Color temperature is mainly used to adjust the color of photos. Generally, the color temperature of natural light will be around 4500k. The higher the value, the colder the photo will be, and the lower the value, the warmer the photo will be.
Door B:
When we press the shutter button / shutter line, B will appear on the camera. At this time, the shutter will remain open and the camera will have mode B. A tripod must be used for door B shooting. It is generally used to shoot the night scene and the starry sky at night.
