Key Reading Summary

ISO, Aperture, and Shutter Speed control exposure. ISO determines the sensitivity of light for the lense. Aperture controls the amount of light passed through the lens or film. The more open it it, the more light that travels through. Shutter speed is the speed at which the curtain opens and closes while taking a photo. These three variables are dependent on each other to make a picture.

Explain, in your own words, what a “stop” is.

A stop is halving or doubling the light in a picture.

Explain how aperture affects depth of field and how you can calculate your depth of field for a given shot (there are 3 variables)?

The three variables are subject distance, aperture, and focal length. If the Aperture is smaller, the depth of field is larger. You have to use an app to calculate depth of field.

What are some considerations when shooting with a slow shutter-speed? How does your focal length impact your shutter-speed considerations?

More motion will be captured when shooting with a slow shutter speed. This will make the picture seem blurry. To not have as much shutter shake, you should set the shutter speed to the inverse of the focal length.

When would you want to use a shallow depth of field?

You would want to use a shallower depth of field when you want the picture to be less in focus.

What I've learned

I've learned that playing with exposure on a picture makes it look a lot clearer and vivid. If I were to take the same picture with no exposure, it would look a lot different. Although understanding stops is hard, the picture in result is worth it.
