aperture (Av)
distance between the closest and furthest points in an image that are in acceptable focus
Depth of Field
Classification of Depth of field
Narrow (shallow or small) Depth of Field
Wide (deep or large) Depth of Field
to have a shorter depth of field
- small amount of image in focus
narrow depth of field
to have a larger depth of field
wide depth of field
wider aperature
smaller f-numbers
smaller aperature
large f-numbers
faster shutter and slower shutter
shutter speed
less light on the image sensor
faster shutter speed
more light in capturing
slower shutter speeds
measure of the sensitivity of the film sensor in a camera
ISO (international organization of standardization)
essential ingredient of photos
- a skill that separates photographers from snap shooters is the ability to solve lighting problems
Light
