Shutter speed is a great tool for perfecting exposure, controlling blurring, and creating interesting effects. Discover what it is and how to use it.

I’ve always believed that in photography, you should avoid getting bogged down in the technical side of your hobby, and focus on developing your creative talent. However, there are certain technical elements that are essential to getting a good photo – shutter speed is one of them.

Shutter speed is 1 of the 3 elements (along with aperture and ISO speed) that determine a photo’s exposure. It also controls how sharp your photos are, and lets you introduce lots of interesting creative effects into your shots. Let’s look at what it is, why it’s important, and how you can use it.
