7241438560	The Exposure Triangle	Aperture, ISO, shutter speed	1
7241445274	Aperture (Lens Pupil)	the diameter of the lens opening the is expressed as f-stop and controls the death of field	2
7241450565	Depth of Field	When you have a large depth of field (small aperture number) and a large focus When you have a shallow depth of field (large number) = small depth of field	3
7241465387	shutter speed	Controls how fast or slow the aperture opens and closes Measured in seconds- fractions for a second Long shutter causes blur and a fast shutter freezes motion	4
