Aperture

Aperture as a Creative Force
Small	Story telling exposures – when you want images that show great depth of field and have foreground, middle ground, and back ground all in reasonable sharp focus.	Use wide angle lenses and/or short focal lengths
f32
f22
f16

Middle	“Who Cares” exposures – when depth of field is of no concern as in when all subjects are within the same focal distance (a child against a wall or a leaf on the ground). These apertures often deliver the sharpest focus and best contrast.	Use “normal” lenses and middle focal lengths
f11
f8

Large	Single subject exposures – when you want to isolate a subject or have a singular theme and want to show a shallow depth of field.	Use “long” telephoto lenses and/or longer focal lengths
f5.6
f4
f2.8
