Camera Shutter Speed Explained
Even though we are going to talk about camera shutter speed you need to be aware of the fact there are three main factors that all work hand in hand with each other. In other words, when you adjust anyone of these three settings it will affect the other two.
The three settings are:
- Camera shutter speed
- Aperture adjustment
- The Cameras ISO
For this post, we are going to talk mainly about explaining the shutter speed. The other two you can check out the posts on each of them to see how they have their primary function on how and why they link together.
So getting back to the topic of camera shutter speed explained I want to pass on this phrase to you.
Shutter Speed = the Length of Time Light hits the Recording Media
The recording media is what we refer to as the sensor in a Digital SLR camera. The light is being directed there to get your picture. So the faster the shutter speed is, the more amount of light is required to hit the sensor to be able to reproduce your image. An example of this would be when you set your camera on a shutter speed of 60; you are telling the camera 60 = 1/60th of a second.
With your camera on this setting, you would be able to take good photo shots of people posing for instance. If you were to select anything slower than this 1/15, for example, you would end up with blurring from any sudden movements. A 1/60 of a second is fast enough to capture some great shots.
In photography, there is a term when using shutter speed called bulb.
Bulb = the shutter will open for as long as you press the shutter button.
This camera effect from controlling the shutter speed in this manner is recognized when you can look at a photograph and see everything in focus except what you could call light streams. The picture below will demonstrate the effect of the street in perfect focus with light streams.
From this photo, you can see the clarity and perfect focus of the street. You will also notice red and white light streams up and down the street as well. When you focus your camera, and this works best on a tripod, so you will eliminate any chances of jiggle. The red lights as some of you may know will be the brake lights and the white are obviously the front headlights of cars driving by in the picture. You see by holding the shutter button pressed everything that is stationary will be in sharp focus and the cars driving by will show their path of trailing lights.
Now faster shutter speeds allow you to capture fast-moving objects that some will refer to Shutter Speed Barriers.
There are two main shutter speed barriers we can look at next.
Shutter Speed Barrier 1:
- When you are shooting people or animals and especially if you are hand holding your camera, try to stay at shutter speeds faster than1/60th of a second.
Shutter Speed Barrier 2:
- When you are attempting to capture the action of a fast-moving subject like a bird in flight, sports, always try to stay at shutter speeds of 1/500th of a second or faster.
The photo of the osprey shows a crisp, clean shot of a bird of prey in perfect focus from wing tip to wing tip. You can also do this with water droplets and spray from moving water to see everything in great detail.
With shutter speed, there is also one more thing I would like to mention that so many people saw the photos but not always known how to accomplish the shot. That is the blurred water flow. If you set your shutter speed for 1/15 of a second or slower, the result will be the blurred water flow look. Again you want to have your camera mounted firmly on a tripod to accomplish this properly. Have your aperture dialed down to f 22 and dropped your ISO to the lowest setting it will go to create shots like below.
So there you have camera shutter speed explained with a few photographs to help see the difference in outcome by the variations you adjust your settings to achieve your results.
