Aperture, Shutter Speed, and ISO

Aperture

F16

F2.8

1. We should closely relate aperture to the pupil of our eye because the bigger the aperture is, the more light it lets in.
2. The smaller the Aperture f-stop, the larger the Aperture
3. Depth of field is what part of the photo is most focused in on. A larger f-number means a smaller aperture, which will make both the foreground and background in focus. A smaller f-number means a larger aperture, which will center in on one point in the photo and blur everything else out.

Shutter Speed

High Shutter Speed

Low Shutter Speed

a.) Medium

b.) Slow

c.) Fast

d.) Fast

e.) Medium

f.) Fast

a.) Slow

b.) Slow

c.) Fast

d.) Medium

e.) Fast

f.) Medium

Auto mode on your camera has the camera decide what aperture and shutter speed you have. In Shutter Priority, allows you to select the shutter speed, but selects the aperture for you. Manual mode allows you to choose both the aperture and the shutter speed on your own.

ISO

ISO 200

ISO 3200

1. Shooting at a higher ISO would help capture the image without a blur when there isn't enough light. If you don't use your flash, you should set it to a higher ISO.
2. When using a low ISO, the author said to use the lowest ISO when there is plenty of light so you can retain detail and have a quality picture. They also said that if you use a low ISO in a dark or dim setting, your camera will probably need more time to capture the image. So be aware if there's any movement!
3. When using a high ISO, the author said to raise it when there isn't enough light. On the DSLR camera there is an "Auto ISO" button that allows you to set the maximum ISO that you want and the camera adjusts according to how much light is available. Works great for low-light settings.

All Three Pillars
