This document discusses technical aspects of photography including camera controls, the history of photography, how light travels through a camera, and the exposure triangle which controls ISO, shutter speed, and aperture. It provides information on ISO and how it relates to image quality and light sensitivity. It also explains shutter speed and how faster speeds freeze motion while slower speeds create blur. Aperture is covered, specifically how small numbers create shallow depth of field while shooting landscapes requires larger numbers for more of the image to be in focus. Quizzes are included to test understanding.

7. QUIZ
1. What did artists use pre-1800’s to
draw/trace with?
2. What does light do to an image when it
travels through a camera?
3. In digital camera’s what reverses the
image?
4. In digital camera’s what does the
photograph produce itself onto?

8. EXPOSURE TRIANGLE

9. EXPOSURE TRIANGLE QUIZ
1. Which component controls the grain?
2. Which component controls the blur?
3. Which component controls the Depth of
Field?

10. ISO
ISO measures the
sensitivity of the image
sensor.
ISO 100 ISO 3200

11. ISO AND NOISE
• The lower the
number (eg.
100) the
finer/smoothe
r the grain.
• Meaning that
the image will
be higher
quality.

12. ISO AND LIGHT
The higher the number (eg 1600) the more sensitive your camera is
to light.
Meaning more light is let onto the image but the quality is poor.

13. to control the amount of time during which the camera
is exposed to light.
'faster' shutter speeds decrease the amount of light and
freeze the image.
‘slower’ shutter speeds increase the amount of light and
can create movement in the image.

24. QUIZ
1. Give a numerical example of a fast
shutter speed
2. Give a numerical example of a slow
shutter speed

25. to control the amount of light entering the lens.
• has an effect on focus and depth of field
APERTURE

26. In the camera lens

27. Small number =
shallow depth of
field.

28. When shooting a landscape, get as much of the
photograph in sharp focus as possible (f11 to f22).
In a portrait, shallower dof (f2.8 - 8) will isolate your
subject from distracting backgrounds

34. QUIZ
1. What F stop would you typically use when
you shoot portraits?
2. Give a numerical example of an F stop that
creates a shallow depth of field.
3. What could you photograph at F22?
4. If you had F22 would more or less light
come through the camera than F5.6?
