How to adjust the speed gate of SLR camera

In the past, the mechanical shutter was faster than 1/60s, and slower than 1/30s was another mechanism, so it was called fast and slow shutter. Digital SLR uses an electronic shutter, and the slower shutter speed is the "slow shutter".

A high-speed shutter is needed to take instantaneous photos of water droplets, and photos above 1/2000s are safer. On rainy days, the light is generally poor. To achieve the shutter speed of 1/2000s, it is necessary to use a lens with a large aperture or a flash with high-speed strobe function. Continuous shooting chooses the best.
