Aperture
- Amount of light you want to allow by varying the size of the hole
- Range is 2.8f to 22f
- 2.8f will allow more light than 22f because 2.8f is actually 1/2.8f. Meaning 1/2.8f > 1/22f.
- Examples:
- lower f will have sharp object with blur backgroud
- higher f is used for landscape
shutter-speed
- higher shutter speed:
- low light
- motion blur
- short shutter speed
- sport or wild life event
- Underexposure: small aperture, short shutter speed
- Overexposure: Large aperture, high shutter speed
ISO
- Sensitivity of the sensor
- Higher ISO may lead to grainy images
- Example:
- sunset: where the light is low but depends on Aperture & Shutter speed
