Fundamentals of Photography
The Trinity of Photography
Aperture is an opening
The bigger the F number, the smaller the aperture
The smaller the F number , the bigger the aperture
The bigger the opening the blurrier the background appears.
The smaller the opening the sharper the focus in the background.
Aperture controls the amount of depth of field.
Shutter Speed
Shutter is like a curtain that opens and closes
To stop motion of somebody walking , the minimum shutter speed is 1/50
To stop motion of somebody running
Shutter speed controls the amount of motion blur in one photo
ISO
ISO is a setting for your camera's sensitivity to light
ISO adjust the sensor in the camera the detects an image
Rule of thumb; use a low ISO when thre is alot of light
When shooting with fast shutter speed, you will have to increase ISO if photos come out too dark.
When shooting at night, you will have to increase ISO for sensor to pick up more light
