Shutter, aperture and ISO are the main feature of a camera that control brightness and sharpness of images.
What are Shutter Speeds?
Shutter speeds is a length of time a camera shutter is open to expose light into the camera sensor. a camera shutter is like a window hat opens and closes to let light in for a certain amount of time. slow shutter speeds allow more light into the camera sensor by keeping the shutter window open for longer. slow shutter speeds are usually used for low-light and might photographs. Fast shutter speeds help to freeze motion by opening the shutter window for a millionth of a second letting light hit the camera sensor really quickly.


in this image the photographer has used a wide camera aperture f/2 to freeze the image, they then used a shallow depth of field to isolate the bird from the background.
Examples – 1 1/2 1/4 1/8 1/ 15 1/30 1/60 1/125 1/250 1/500 1/1000
What are Aperture Settings?
An aperture is an opening within the lens which light ravels into the camera. the longer the aperture is open the more light passes into the camera sponsor. aperture controls the depth of field, which is a portion of a scene/ photograph that is sharp. if the aperture is very small the depth of field id large, if the aperture is large the depth of field is small. Aperture is expressed in “f” .
Example – F/1.4 F/2.0 F/2.8 F/4.0


Depth of Field

In this image the photographer has used a shallow depth of field
What is ISO?
ISO is a way to brighten your photos if you cant use a wide aperture or a longer shutter speed. raising your ISO can also increase the graininess and noise in your images. ISO is measures in numbers. lower numbers representing a darker image and higher numbers representing an a brighter image.
Example – 100, 200, 400, 800, 1600

These are some photographs that i took using Aperture, shutter speed and ISO.
