What Is Shutter Speed?
You know that unmistakable sound you hear when you’re snapping away with your camera? What you’re actually hearing is the camera’s shutter. The shutter moves the same way every shot you take. However, depending on the shot you’re taking, it doesn’t move at the same speed every time. So what is camera shutter speed exactly? Let’s dive into the definition of camera shutter speed and the uses of the different camera shutter speeds. We know that your camera takes photos by exposing a sensor to light. The button you press on the top of your camera is the shutter release that opens the shutter. This is the moment when the image you’re photographing gets recorded. The camera shutter speed is determined by the length of time it stays open exposing light to the image. It’s critical to understand the definition of photography shutter speed to capture the best images. If your photography shutter speed is too fast, and the shutter doesn’t stay open long enough, your images could be too dark. Here are some uses of shutter speed explained to help you take quality images in the future.
Slow Shutter Speed Uses
When choosing to use a long shutter speed, the sensor on your camera is exposed for a longer amount of time. Anything from 1/100th second to 1 second will be hard to shoot handheld because of camera and lens shake. When using slow shutter speed photography, you can create a motion blur effect. This is a technique you may find useful when photographing moving cars or motorcycles to show motion in your images. If you like to shoot objects in the night sky like the Milky Way, slow shutter speed photography is ideal. Just remember to use a tripod when shooting in low light. This form of slow shutter speed photography will keep everything else around the water in sharp focus.
Fast Shutter Speed Uses
Shutter speed settings can also be used to freeze motion. A shutter speed setting is considered to be a high shutter speed if it is faster than 1/500th of a second. If you have the Sony A9 from Buydig.com, your mechanical shutter has a high shutter speed of 1/8,000th second. It’s at the very top of the high shutter speed for sports with the electronic shutter making it capable of 1/32,000th seconds! With this high shutter speed, you can freeze your favorite football player in the middle of a touchdown pass. Capture a unique shot of a drop of water in midair using high shutter speed settings also.
The Aperture and ISO Relationship to Shutter Speed
Shutter speed is just one of three different settings that affect exposure. When taking a photo, a certain amount of light is needed to expose it correctly. By adding a stop of light, this doubles the exposure to brighten an underexposed image. If you need to darken and overexposed image, you’ll decrease the exposure by one stop. This cuts the amount of light in half. Adding and decreasing stops is done by making changes to the exposure triangle, or the ISO, aperture and shutter speed. We’ve discussed shutter speed control already. Aperture actually refers to the size of the hole in the Sigma lens from Buydig.com that lets in light. When you increase the exposure by one stop, you double the opening, and vice versa. ISO is more or less the sensitivity of the digital sensor. If the value of the ISO is high, the sensor doesn’t need to collect as much light for an exposure. Knowing how the exposure triangle works will give you the most creative control over your images
