The shutter speed controls how long light enters the lens and hits the image sensor or film plane. The shutter speed enables you to capture the world in split seconds, but it can also absorb the world at speeds upwards of three and four seconds or remain continually open up until the photographer wants to close the curtain. Snapping the shutter in a fraction of a second, also gives you control on how motion is recorded.
If the shutter speed is faster than the object or background, then the image will be tack sharp. Think about the rain in a rainstorm, how fast is that water falling? Then you can review the three or more exposures, see the subtle but critical differences in the images, and decide which one is the best image for your purposes.
In the three images in the above example, you might prefer the overexposed by 2 stops image because the setting sun is most brilliant. Bracketing was a technique that was popularized from shooting slide film, due to the limited ability to correct the image in the darkroom.
Many photographers still use the technique today, so they have the exposure that they want. The smaller the hole, the sharper the image.
And the smaller the hole, the longer you would have to pull the tape off that hole to allow light in to get a decent exposure. This is because a smaller hole lets in less light. The same principle is at play in your lens. The smaller the aperture, the less light comes into your camera.
The larger the aperture, more light goes in. Where some people get confused is with the f stops. Something called depth of field also comes into play when you adjust your aperture. Portrait photographers like to use this technique to make their subjects stand out. Landscape photographers tend to shoot at narrow apertures. Shutter speed affects your photos differently than the aperture. Aperture vs. Shutter Speed. Comparison chart Aperture versus Shutter Speed comparison chart Aperture Shutter Speed Definition In photography, aperture refers to the diameter of the aperture slot.
When expressed as an f-number, it refers to the focal length of the lens divided by the aperture diameter. Shutter speed refers to the length of time that a camera's shutter is open, i. Use Aperture controls the distance range for how far away objects can be from the camera for them to appear sharp and in focus in the picture. Shutter speed is used to provide a sense of movement and is important in capturing images for objects that are not still. Follow Share Cite Authors.

Comments: Aperture vs Shutter Speed. For example, for the same quantity of water, you can get away with less time in the rain if you pick a bucket that's really wide. Alternatively, for the same duration left in the rain, a really narrow bucket can be used as long as you plan on getting by with less water. In photography, the exposure settings of aperture, shutter speed and ISO speed are analogous to the width, time and quantity discussed above. Furthermore, just as the rate of rainfall was beyond your control above, so too is natural light for a photographer.
Aperture : controls the area over which light can enter your camera Shutter speed : controls the duration of the exposure ISO speed : controls the sensitivity of your camera's sensor to a given amount of light.
One can therefore use many combinations of the above three settings to achieve the same exposure. The key, however, is knowing which trade-offs to make, since each setting also influences other image properties. For example, aperture affects depth of field , shutter speed affects motion blur and ISO speed affects image noise. The next few sections will describe how each setting is specified, what it looks like, and how a given camera exposure mode affects their combination.
A camera's shutter determines when the camera sensor will be open or closed to incoming light from the camera lens.
The shutter speed specifically refers to how long this light is permitted to enter the camera. By the Numbers. Shutter speed's influence on exposure is perhaps the simplest of the three camera settings: it correlates exactly with the amount of light entering the camera. For example, when the exposure time doubles the amount of light entering the camera doubles. It's also the setting that has the widest range of possibilities:.
How it Appears. Shutter speed is a powerful tool for freezing or exaggerating the appearance of motion:. With waterfalls and other creative shots, motion blur is sometimes desirable, but for most other shots this is avoided. Therefore all one usually cares about with shutter speed is whether it results in a sharp photo — either by freezing movement or because the shot can be taken hand-held without camera shake.
How do you know which shutter speed will provide a sharp hand-held shot?
