What is aperture?
Diameter of the hole inside the lens
What happens when you change aperture?
Amount of light let into the camera changes
Does a wide aperture let in more/less light?
Wide aperture lets in less light
What is the relationship between aperture and light?
Wide aperture (f/1.4) lets in more light
Narrow aperture (f/22)lets in less light
What is relationship between depth of field and background?
A shallow depth of field has a blurred background
A deep depth of field has a sharp background
What is f-stop?
f-stop is the ratio of the focal length of the lens to the diameter of the aperature
What is shutter speed? What does shutter speed have to do with light?
Shutter speed is the length of time the camera's shutter is open
Shutter speed controls the amount of light that reaches the sensor
What does shutter speed do in relation to light and motion
A slow shutter has more light, captures motion
A fast shutter has less light, freezes motion
What happens when you decrease shutter speed?
Decrease the amount of light let in
What is estimate of motion blur?
object velocity x shutter speed
What does a sensor do?
sensor (detector) captures the light
What are the paremeters of a sensor?
sensitivity (ISO), resolution
