Aperture and
Depth of Field
– an adjustable opening in a diaphragm in a lens
Aperture Lens Opening = Aperture = f-stop
Lens Opening = Aperture = f-stop 2.8 * 4 * 5.6 * 8 * 11 * 16 * 22
Larger Smaller More light Less light More exposure Less exposure X 2 X 1/2 Less depth of field More depth of field

How to take the picture
Lens Opening = Aperture = f-stop 2.8 * 4 * 5.6 * 8 * 11 * 16 * 22
Larger Smaller More light Less light More exposure Less exposure X 2 X 1/2 Less depth of field More depth of field
Lens Opening = Aperture = f-stop Largest Smallest
Larger Smaller More light Less light More exposure Less exposure X 2 X 1/2 Less depth of field More depth of field
Where to focus ?
Where to focus ?
Shooting for depth of field
Use Aperture Priority
Lens Opening = Aperture = f-stop
Largest Smallest
Larger Smaller More light Less light More exposure Less exposure X 2 X 1/2 Less depth of field More depth of field
