Camera shake is a common issue that results in noticeable blur in images. It is often caused by using a slow shutter speed. When you take handheld shots, even the slightest vibration can lead to a blurry photo. This is particularly true during the brief moment the shutter is open.
Understanding Shutter Speed
In bright daylight, aim for a shutter speed of at least 1/250 seconds to avoid camera shake.
In low-light situations, such as indoors or at night, you may need to use a slower shutter speed. It is typically around 1/100 seconds or slower. This allows more light into your camera.
Know Your Gear
Different cameras and lenses have varying capabilities regarding minimum shutter speeds. For example, longer lenses are more susceptible to camera shake than shorter ones. This is due to physics; holding your arm extended away from your body makes it harder to keep steady.
To minimize shake, keep your elbows tucked in close to your body while shooting.
Reciprocal Rule
A useful guideline is the reciprocal rule: the minimum shutter speed to prevent camera shake is 1/(focal length). For instance, if you’re shooting at 100mm, your minimum shutter speed should be 1/100 seconds. For a 50mm lens, aim for 1/50 seconds.
Here’s a quick BTS look. On the left is the final shot, and on the right is the raw view through my viewfinder. My settings were f/1.8, 1/100, and ISO 250.
To keep the shot steady, I leaned close to the ground to minimize camera shake. I also used focus peaking. The red outlines you see are a lifesaver for low-light photography. They help when autofocus starts to struggle!
1/(focal length x 2)
Some photographers recommend adjusting the calculation for shutter speed by doubling the formula, using 1/(focal length x 2). This approach is safe when working with telephoto lenses, such as those in the 135-200mm.
For even longer lenses, like 300mm-800mm, I highly recommend using a monopod or tripod. This will guarantee stability. It will also reduce the risk of camera shake.
Image Stablization
If your camera or lens has In-Body Image Stabilization (IBIS) or vibration reduction, turn these features on. This can provide extra leeway for using slower shutter speeds. It allows more light without introducing blur. For example, I can shoot at 1/30 seconds handheld without experiencing camera shake.
Individual stability varies. For some people, even a shutter speed of 1/100 seconds can lead to blurry images. This happens if their hands are unsteady.
Leaning for Stability
Lean against a solid object like a wall, pole, or railing. This might help you achieve sharper images with slower shutter speeds. This could be as slow as 1/4 seconds. This technique maximizes light intake without increasing ISO, helping to eliminate noise and motion blur.
