What Shutter Speed Should I Use With My Camera?

Author: Harry Guinness / Source: How-To Geek

Shutter speed is one of the three most important settings for your camera—the other two being aperture and ISO. The shutter speed you use changes how the whole image looks. Here’s how to select the right speed.

The Reciprocal Rule and the Minimum Hand Held Shutter Speed

Shutter speed is also called exposure time.

It’s a measure of how long camera’s shutter stays open to let light in. Both 1/1000th of a second and one second are shutter speeds. Most cameras can do between 1/8000th of a second and 30 seconds natively. That’s a pretty huge range.

One thing you have to be careful of, though, is that you don’t use a shutter speed that’s too slow if you’re hand holding your camera. It’s tough to hold a camera totally steady; if the shutter speed is too slow, the small amount of handshaking and body movement will show up in the image as motion blur.

In general, the guideline is that the minimum handheld shutter speed is the reciprocal of the focal length of the lens. So, if you’re using a 100mm lens (and remember to account for crop factor) then the slowest shutter speed you should try and use is 1/100th of a second. For a 40mm lens, it’s 1/40th of a second. For a 16mm lens, it’s 1/16th of a second. And so on.

In the image below you can see this in action. I took the same photo with a 40mm lens at eight different shutter speeds: 1/200th, 1/100th, 1/80th, 1/40th, 1/20th, 1/10th, 1/2, and one second. You can see there’s a severe drop off in sharpness between 1/40th and 1/20th.

While there are exceptions and ways to extend it, it’s a good principle to keep in mind when you’re selecting a shutter speed.

If you want to go slower, you should use a tripod.

With that said, let’s look at what each shutter speed range is good for.

Faster Than 1/500th of a Second

There are two main ways to show motion in your images: either by freezing it or blurring it. Shutter speeds faster than around 1/500th of…
