1. What is depth of field?
Depth of field is how close the focused subjects in a photograph are, or the area that is in focus.
2. What is an aperture?
Aperture is the opening in the lens which indicates how wide they are opened.
3. Which aperture creates the shallowest depth of field? Which puts everything in focus?
An aperture of f/1.8 creates the shallowest depth of field, and a larger one, like f/22 puts the entire photo in focus.
4. What does “stop down” mean?
Stop down means to narrow the aperture, or create a deeper depth of field.
5. What do you have to do to make all three people sharp?
You have to close/stop down the aperture to f/22.
6. What happens to the shutter speed as you stop down to increase depth of field?
As you stop down the aperture, the shutter speed gets larger(slower).
7. What mode do you need to set the camera on to control the aperture?
You have to set the camera on Av or Aperture Priority mode.
8. What is a “fast lens”?
A fast lens is a lens with a large maximum aperture opening, like f/1.8.
9. The aperture is an opening controlled by what?
Aperture is an opening in the lens controlled by blades.
This was taken with f/4.0, a shutter speed of 1/350, and an ISO of 200. This picture has the blurriest background. You can barely see the car in the background, and the second bike is not in focus.
This had an aperture of f/8.0, 1/180 shutter speed, and an ISO of 200. The background is more in focus than the first picture, but you can't see the details.
This one was taken with f/27.0, 1/8 shutter speed, and 200 ISO. The other bikes are in focus, and the car is almost focused.
You nailed this assignment. They are the best examples for Photo Challenge 2 that I have seen so far. 100. 100.
