How does the slow door of SLR camera capture the atomization effect of waterfall?

If you shoot during the day, ISO 100. The aperture is between F 18-F22, so the shutter will be between 1/6 and 1/3. If your lens aperture is relatively small, such as F32, the shutter can be slower than 1 sec. You can take more photos.

Just make sure that the shutter is exposed correctly within a few seconds. Maybe overexposure will be a problem. Turn down the aperture. If you can't reach the slow door, you may need to add a filter.

Extended data:

Shutter is the mechanism used by camera to control the effective exposure time of photosensitive film, and it is an important part of camera. Its structure, form and function are important factors to measure the grade of a camera. Generally speaking, the larger the shutter time range, the better.

The unit of shutter speed is "seconds", and the highest shutter speed of professional 135 cameras reaches116000 seconds. Common shutter speeds are:11/21/41/811/301/65438+.

The shutter speed exposure of two adjacent stages is twice different, and we often say that the difference is one stage. For example, the exposure of1/60s is twice that of1125s, that is,1125s is one step slower or one step lower.
