Exposure
Name:____________________________________________________Block________
Directions:
Google “good photographic exposure photos” and go to images to view good exposures.
Go to this link, read and answer:
1. Correct exposure of a photo in one that is not too dark or not too light.
If exposure is like collecting water in a bucket, and it is underexposed, it is
too_______________. If it is overexposed it is too__________________.
2. Exposure is determined by 3 interconnected factors. List them.
3. Shutter speed: controls the _______________________ of the exposure
Which shutter speed is faster, 1/60 or 1/125?
4.The shutter speed specifically refers to how _______________ light is permitted to enter the camera
5. If you want to freeze or stop the action of a running football player the best shutter speed range is________________________________________
6. If you are using a slow shutter speed such as 1/15 and you are hand-holding a camera, your
photograph may be ___________________________so you might want to attach your camera to a
___________________________
7. Aperture: controls the area over which light can _____________________ your camera. This means it con
trols the amount of light that enters a camera.
8. The size of an aperture is referred to as f/stops. Think of f/stops as fractions. Which pice of pizza is bigger,
1/2or 1/8?______________
9. So which is the larger lens opening or f/stop, f4 or f16?_________________ Which lets in the least
amount of light?_______________
10. A camera’s aperture setting is what determines a photo’s depth of field (the range of distance over which
objects appear in __________ focus). Lower f-stop values or larger lens openings correlate with a shallower
depth of field. Search depth of field so you understand it.
11. Which f/stop should have the largest depth of field, f/16 or f/4?______________
12. ISO speed: controls the sensitivity of your camera’s sensor to a given amount of _______________
13. ISO is similar to shutter speed, it also correlates 1:1 with how much the exposure increases or decreases.
However, unlike aperture and shutter speed, a _____________________ ISO speed is almost always desirable,
since higher ISO speeds dramatically increase image noise. As a result, ISO speed is usually only increased from
its__________________________ value if the desired aperture and shutter speed aren’t otherwise obtainable.
14.An ISO setting of 100, is used when a __________________________amount of light exists. You may need to
switch to large ISO setting such as IS0 3200 when a _____________________of light exists.
15. Describe digital image noise. Google an image and draw it or read and describe:
16. Which setting would produce more image noise 100 or 3200?_____________
17. With digital SLR cameras, a range of _________________-__________________ (or higher) is often acceptable.
