3. You’re Causing Camera Vibration
Using a tripod is the most common tip when talking about how to capture sharp images. However, simply mounting the camera on a tripod won’t necessarily result in the sharp images you expect.
When pressing the camera’s shutter button, you create a small amount of vibration. While it might not seem like much, it’s enough to cause blur or softening when using semi-slow shutter speeds.
Make sure that you use either a remote shutter release or the camera’s built-in delayed shutter when the camera is mounted on the tripod. This will eliminate the vibration caused by pressing the shutter button and ultimately lead to a sharper image.
