Aperture, Shutter Speed, and ISO

APERTURE:

Aperture F2.8

Aperture F16+

1. We closely relate aperture on a camera with our eyes (pupil).

2. The smaller the aperture the higher the number, and the higher the aperture the lower the number.

3. The aperture makes the depth field more or less focused with the main subject. The smaller the aperture, the more focused the background is. When the aperture is larger, the background is more blurry and the foreground is sharper.

SHUTTER SPEED:

High Shutter speed

Low Shutter speed

when the sun was still up:

a. low shutter speed

b. low shutter speed

c. high shutter speed

d. high shutter speed

e. low shutter speed

f. high shutter speed

when the sun is down:

a. low shutter speed

b. low shutter speed

c. high shutter speed

d. high shutter speed

e. high shutter speed

f. high shutter speed

2. 3 settings: the first is an auto setting, where the shutter speed (& aperture) are adjusted by the camera. The second is a manual setting called "Shutter Priority" mode, where you can choose the shutter speed, but the aperture is still adjusted by the camera. The third is a manual setting called "Manual" mode, where the photographer adjusts both the shutter speed and aperture.

ISO:

ISO 200

ISO 3200

1. An advantage of using a higher ISO in a nighttime setting is that more light can be taken in without creating a blur. Another advantage is that the photographer is able to capture "ultra-fast shots".

2. When choosing ISO, try to use the lowest ISO possible to get the highest quality. Also, they recommend using a tripod if you want to create the "ghost effect".

3. When shooting with high ISO, they recommend shooting in low light or indoors to capture the image without creating a blur.
