Canon EOS-50d basic operation guide and photography skills?

First, the shutter use skills of Canon 50d

The shutter determines the opening time of the camera hole. If you drive for a long time, more light will enter; If the opening time is short, there will be less light, as simple as that; It's not just that.

High-speed shutter means that you can capture fast movements, such as athletes' movements, splashing water droplets and so on. The disadvantage is that there is too little light entering the camera, so the photo will become very dark. Instead, a slow shutter can be used to compensate for dim light conditions. The longer the hole is open, the more light will enter.

Second, the aperture using skills of Canon 50d

When the shutter speed is equal to the opening time of the hole in the camera, the aperture represents the opening size of the hole. The larger the aperture, the more light; The smaller the aperture, the less light.

The size of the aperture is indicated by "f". It is easy to confuse that a large F value represents the opening of a small hole, while a small F value represents a large hole. So f/4 is a large aperture but f/ 1 1 is a small aperture; When the camera is in manual mode, press and hold the aperture button to adjust the aperture size, rotate the command dial, and observe the value displayed on the LCD.
