The three pillars of digital photography are ISO, aperture and shutter speed. People involved with digital photography must know the uses of these three controls to achieve desired images with his/her device.
In my previous article, I discussed the basics of ISO. To know about ISO, please read the Digital photography: ISO.
In this article, I will discuss the shutter speed and then how this can affect your image.
What is Shutter Speed in Photography?
First of all, we should know what shutter speed is.
Every time you capture an image with your digital camera, the device opens up its shutter for a certain period of time. The image lens opens up to the light within the time and captures what it sees. Whatever your lens sees within the time later becomes your image. The time between opening and closing the shutter is known as shutter speed.
How Shutter Speed is Measured?
Shutter speed can be a second, less than a second or just a fraction of a second.
It is mostly referred as 1s, 1/2s, ¼s, 1/250s, 1/500s, etc. The faster your shutter speed is, the shorter the time your image sensor is exposed to the light.
On the other hand, the slower your shutter speed is, the longer time your image sensor is exposed to the light.
Fast, Slow and Long Shutter Speeds
Different shutter speed will affect your image in different ways.
Faster shutter speed will help you to photograph motion objects as it has the power to freeze the moving object. Besides, slower shutter speed will get blur effect on the image.
Many photographers intentionally keep the shutter speed at a lower level to get blur effect. If you want to capture an image of moving cars in the night or flowing water of the river then it is always wise to keep your camera’s shutter speed at a lower level.
There are many other things that can be adjusted with shutter speed, however, this is the basic of shutter speed.
I believe anyone can master the shutter speed after spending a little bit of time with the digital camera.
