This document discusses various photography concepts including shutter speed, aperture, and ISO. It provides examples of different shutter speeds, apertures, and ISO settings and how they impact images. Specifically: 1) Shutter speed controls the amount of time the shutter is open, with faster speeds freezing motion and slower speeds blurring it. 2) Aperture refers to the size of the lens opening, with larger apertures decreasing depth of field and smaller ones increasing it. 3) ISO measures the image sensor's light sensitivity, with higher ISO settings allowing faster shutter speeds in darker situations.

2. Shutter speed is the amount of time that the shutter is
open.
Shutter speed is measured in seconds. The bigger the
denominator the faster speed in 1/1000 is much fast
than 1/30. To freeze movement in an image you’ll want
to choose a faster shutter speed. To let the movement
blur you’ll want to choose a slower shutter speed.

3. In this photo our goal was to
freeze the movement of the
water, so, we have used a fast
shutter speed.
F= 5,6
ISO= 100
1/1000 seg

4. In this photo we can see the cars moving and the
mountain with no movement , the only thing that
we have done to get this goal is use a slow shutter
speed.
F= 20
ISO= 100
1/3 seg

5. ISO measures the sensitivity of the image
sensor.
Higher ISO settings are generally used in
darker situations to get faster shutter speeds.

6. As we can see in this photo we have used high
ISO to achieve light to this picture.
F= 4,8
ISO= 1600
1/5 seg

7. This photo was taken with the same conditions
of the other photo, but here we have used a low
ISO, so the photo is dark.
F= 4,8
ISO= 100
1/5 seg

8. Aperture is the size of the
opening in the lens when a
picture is taken.

9. This photo we want that
the first grass leaf have a
good image but the other
grass appear blurry, to
achieve this we have used
a large aperture.
F= 25
ISO= 100
1/500 seg

10. In this photo we want that the persons and the
trees that appeared, can see with the same
conditions, to achieve this we have used a very
small aperture.
F= 5,6
ISO= 100
1/640 seg
