Examples of Aperture, Shutter Speed and ISO



Aperture - Wide(F2-F4)




Aperture - Narrow (F16-F32)



The aperture is one of the three components that can be used to select or completely focus on an object in the photograph by changing the size of the opening that allows light through the sensor. When the size is wide, like f32-f11, the picture tends to be blurry in the background since there is more light coming through the sensor. And when the size is narrow, like f4-f1.4. there is less light, therefore this results in the background becoming more clear, which is shown above.

Shutter Speed - Fast



The Shutter Speed is how quickly or slowly the shutter opens and closes. When the shutter speed increases its number to 1/1000-1/125, the shutter closes faster resulting in moving objects in the photo to freeze completely still. Furthermore, when the shutter speed is low, like 1/8-1/2, the moving objects end up becoming blurry and unclear. When the shutter speed is high the photos tend to give a cool effect since viewers are seeing random objects such as water or beings define gravity or time and when the shutter speed is low the photo makes the image look as if time is speeding up or passing by quickly.

ISO is the sensitively of the sensor. When the image has low ISO, like 150-200 the photo has finer grains, unlike high ISO, like 400-25600, the image ends up gets more grainy. When the ISO is low it creates a more clean edge, unlike high ISO which gives you a more eerie look.
