Photography Basics: Aperture, Shutter Speed, and ISO
Mastering exposure is crucial for great photos.
Aperture
- Controls depth of field (DOF)
- Wider aperture (smaller f-number) = shallow DOF
- Narrower aperture (larger f-number) = deep DOF
Shutter Speed
- Controls motion blur
- Fast shutter speed freezes motion
- Slow shutter speed creates blur
Balancing these elements is key to photography.
