PHOTO Test 1 Exposure, Shutter Speed, Bracketing, Equivalent Exposure
Which shutter lets in the most light?
1 second (B)
Which f-stop lets in the most light?
1.4
Which shutter lets in the least light?
1/2000
List the Standard Shutter Speeds
2000 - 1000 - 500 - 250 - 125 - 60 - 30 - 15 - 8 - 4 - 2 - 1 - B
Which f-stop lets in the least light?
45
What are the Standard Apertures (F-Stops)
45 - 32 - 22 - 16 - 11 - 8 - 5.6 - 4 - 2.8 - 2 - 1.4
What is Equivalent Exposure?
Both shutter speed and aperture change to produce the same amount of light at different exposures
What does aperture (f-stops) do?
Manage light by controlling the intensity of the light entering through the diaphragm
What does shutter speed do?
Manage the light by controlling the time light is allowed to strike film
What is Bracketing?
Purposeful one stop over exposure and one stop under exposure
Give an example of bracketing for depth of field.
Starting at 1/125@f8 Over exposed (+1) = 1/[email protected] Under exposed (-1) = 1/125@f11
Give an example of bracketing for motion (shutter speed).
Starting at 1/125@f8 Over exposed (+1) = 1/60@f8 Under exposed (-1) = 1/250@f8
Give an example of an equivalent exposure.
Starting at 1/[email protected] 1/500@f4 1/125@f8
