Depth of field

What are the 2 key elements of photography

exposure and depth of field

What is depth of field

everything excluding the point of focus that appears acceptably sharp within an image

(point of focus will always remain sharp)

Describe deep DOF vs shallow

Deep - everything appears acceptably sharp

Shallow = only the POF appears acceptably sharp

Effect of aperture on depth of field?

SMALL APERTURE = DEEP DOF (f/22 small hole)

BIG APERTURE = SHALLOW DOF (f/4 big hole)

What are the 3 factors affecting DOF

Aperture

camera to subject distance

focal length

Explain how camera to subject distance effects DOF

Further away - deeper DOF

Too close - shallow depth of field

Explain how focal length affects DOF

SMALLER focal length = wider Field of view = further = deeper DOF

LARGER focal length = narrower FOV = closer = shallower DOF

What is the rule of thirds?

Your Point of Focus should be 1/3 of the way in to the image
