Review of last week's lesson on aperature. You may refer to the notes on this weebly page or to the powerpoint show from last week's lesson. Answer the following questions in a word file.
1. What is another name for the lens aperture? Hint: Your eyes have these same openings.
2 . What does the aperture control?
3. What is exposure?
4. If a photo you take is too dark, it is said to be what?
5. If a photo has too much light, and the subjects look washed out, this photo is said to be what?
6. In your own words, what is depth of field?
Part II
Here is a chart of f-stops:

Part II
Here is a chart of f-stops:
Each stop up or down doubles the amount of light that the lens lets in. How much more light comes into the camera when you move from f2.8 to f1.4?
Apertures of f-stops also affect depth of field. Look at your previous notes again. A wide f-stop or a fast f-stop, say, 1.4 or 2.8 gives shallow depth of field. A small or slower f-stop, say f16 or f22, gives deep focus.
Look at these photos. Guess what type of f-stop was used to create them, based on depth of field:

Why did you choose shallow
or deep focus for each shot?

Now, try the following:
1. Get your camera and find out where the shutter speed control is.
2. Take photos inside the classroom at a fast shutter speed, 1/250th and 1/500th of a second, and then take one at 1/125th and at 1/60th of a second. How do your photos look?
3. We will go outside for about 5-10 minutes in the courtyard. Take photos at the different shutter speeds. Take a couple at fast shutter speeds, some at the intermediate speeds of 1/125th and then take some at 1/60th.
We'll come inside and look at them. How many of them are properly exposed? Is the problem inside for underexposure of overexposure? Is the problem for outside shots that you will under or overexpose them?
