Shutter Priority Mode
“S” or “TV” Mode
Shutter priority mode is one of the settings between automatic and manual. It allows you to select the Shutter Speed and ISO and the camera will calculate all of the other settings.
The Shutter priority mode is useful to control the blur in a picture. If you want a moving object frozen in time, pick a fast shutter speed (e.g. 1/2000). If you prefer to have some blur to show that there is movement, use a slightly slower speed. Vehicles, sport and water are all good examples of pictures that will change dramatically depending on the speed of the shutter.
Using a filter and slowing the shutter speed can have great results when shooting moving water!
The downside of using a fast shutter speed is that the Aperture will be open wide and the picture could lack depth of field. This is what you’ll need to consider when using this mode.
- Fast motion needs a fast shutter speed in order to freeze it. This will decrease the amount of light you are able to capture. You can adjust ISO to give yourself a bit more margin for shutter speed, but this risks increasing the noice and spoiling the picture.
- There are some instances where you don’t need a fast shutter speed but your shots in Aperture Priority (or another mode) come out slightly blurry because you are unable to hold the camera quite still enough. If this is the case, try switching to Shutter Priority and increasing your shutter speed slightly to compensate.
- A general rule to begin with is that you want the fraction of the second to be the same as or higher than the focal length of your lens. For example, if your shooting at 30mm, start with a shutter speed of 1/30 or faster. You can always increase it if necessary.
