Unit 3- Shutter & aperture, ISO & WB Flashcards
why does the shutter open during an exposure
the shutter opens during an exposure so light can expose the image sensor
what is the effect of a slower shutter speed
image gets lighter
what is the effect of a faster shutter speed
lets less light strike the image sensor so the image is darker
explain the effect of a longer shutter length on motion
the more a moving subject will be blurred, also you are more likely to cause blur by moving the camera slightly.
explain the effect of a short shutter length on motion
fast shutter speed opens and closes quickly so a moving subject doesn’t move very far during the exposure
how would you change your shutter speed to capture, or freeze, action.
the faster the subject is moving the faster the shutter speed must be.
the higher the F-stop # the (more/less) blurred moving action is
less
the lower the F-stop # the (more/less) blurred it is
more
what are stops
shutter speed settings
what are the three types of shutters
- electronic
- leaf
- focal plane
movement can be effectively conveyed in a photograph which can reveal…….
drama and grace that are missed with the naked eye.
in addition to the exact shutter speed, what two other factors influence a sharp and frozen subject
its size and distance
what is the backdoor method to attaining fastest shutter speed
- use aperture priority mode
- select widest available aperture
- if the speed still doesn’t seem fast enough, increase the ISO setting.
panning is easiest with what kind of lens
standard or short telephoto lens
how do you freeze your subject against a blurred background
-follow your subject with the camera
