Shutter Speed
Shutter speed in photography is the amount of time the shutter stays open or the length of time that the image sensor is exposed to the scene that is being captured. The shutter speed is measured in seconds and the larger denominator for example 1/500th of a second is much faster than 1/8th of a second.
The faster shutter speed allows less light in than a slower speed which allows more detail and sharpness to the picture.
Example of Fast Shutter Speed
The fast shutter speed allows less light than a slow speed, highlighting the detail in the picture. This speed is best for motion shots and action shots like the Polo image above because of its ability to capture the shot in the most split second when to our eye or a slower shutter speed would be blurred.
Example of Slow Shutter Speed
A slow shutter speed means the image sensor is open for longer than a faster shutter speed which lets in more light. You can tell a slow shutter image that is in motion by the blurred lines of motion and light without the details.
Aperture
In photography, Aperture is basically a hole in your camera’s lens that lets light pass through. It is measured in F-Stops: The larger the F number the less light gets through the lens and the smaller the F number the more light gets in the lens. A large aperture means a large amount of light, however, it is given a smaller F-number.
Example of Wide Aperture
Aperture affects the depth of field in an image or how much of the image appears to be in focus. Large apertures like f/1.8 have a very thin depth field, good for pictures of things like portraits. Landscape photographers would use smaller apertures like f/8, or f/16 to capture the foreground and background and have it all be as sharp as possible.
Example of Narrow Aperture
ISO
I chose to study ISO more a lot more in depth. Like Shutter Speed and Aperture, ISO controls the brightness of your photos and essential to taking the best possible pictures. ISO is the camera setting that will brighten or darken a picture. As you increase the number your photos will grow brighter. It is a good tool to use in dark environments such as astronomy shots. Higher numbers have more sensitivity as well as more grain/noise in an image.
Example of a High ISO image
The image above was taken with a high ISO. Since it was night time, the high ISO is able to expose more of the light to brighten up the photo and capture the stars in the sky that would otherwise be invisible. This picture puts to use a high ISO, a wide aperture, and a slow shutter speed.
