There are three key settings in photography that all are related and impacted by the other: Shutter Speed, Aperture and ISO.
This article is about shutter speed.
Shutter speed is the amount of time that the shutter stays open.
The longer the shutter speed, the more light and “Information” that is exposed to the sensor. In addition, the longer the shutter speed, the more difficult it is to capture action shots without “Blur”
The shorter the shutter speed, the less light that comes in, but also the clarity of motion shots is improved as the scene becomes frozen with faster shutter speeds.
One thing to keep in mind is that to blur water, waterfalls etc…it is possible to use a neutral density filter that essentially darkes the scene allowing for longer shutter speeds without over exposing of the photograph. There are two types… a screw in type that would mount to the end of your lens. The other type is a square type that requires a special mount that would then hold the special square lenses. I am just learning about these and will write more about these in future posts.
