What would you do if you wanted to take the following photos?

The answer is to properly control your shutter speed. If it is a normal DC, you need to adjust it to manual mode. If it is a higher-end DC or DSLR, a simple method is to use the shutter priority S-MODE.

Use S-MODE/Tv-MODE to Control the Shutter
In S-MODE, the thing you can control is the shutter speed. The shutter speed has two main uses:

  1. A very fast shutter (e.g. 1/4000 second) can “freeze” objects in motion, and stop moving objects in an instant, such as a sports car in a race, dripping water droplets, etc.
  2. A very slow shutter (such as 5 seconds) can record what happened over a period of time, such as a flowing river, a busy street, etc.

Points to Note For Slow Shutter And Fast Shutter

  1. For fast shutter, because the opening time is relatively short, so it can absorb less light than normal, so in order to avoid underexposed, be sure to pay attention to the aperture is large enough, but because the aperture is large It will affect the depth of field, so sometimes we need to use a higher ISO or directly use the flash to fill the light.
  2. For slow shutter speed, because it takes a long time to open, basically if you hold it in your hand, there will be a high chance of hand shake, so slow shutter speed will generally be used with a tripod. And because the slow shutter absorbs more light than normal, there will be overexposed in a well-lit environment. In this case, we use a small aperture, a low ISO, or a light reduction filter to reduce the light came in.
