Introduction to Photography
Exercise 2.1 and Exercise 2.2
Exercise 2: Exposure
The second exercise is divided into 3 areas (2a. Aperture, 2b. Shutter Speed & 2c. ISO), all of which directly control the quality of an exposure. This exercises will give the students’ an understanding of how the 3 aspects work in combination to create an exposure.

2a) Aperture (5%)
Marking Criteria: The student must capture the evidence of the Aperture’s influence in exposure using the various f-stops. The student must also capture the evidence of the Aperture’s influence on depth of field.

2b) Shutter Speed (5%)
Marking Criteria: The student must capture the evidence of the Shutter’s ability to freeze fast moving objects and blur moving objects.
Marking Criteria: The student must capture the evidence of the Shutter’s ability to freeze fast moving objects and blur moving objects.
2c) ISO (5%)
Marking Criteria: The student must capture the evidence of degradation of image as the ISO increases in sensitivity. The student also must produce evidence that ISO can directly affect exposure.

notes:
- Big aperture hole = Depth of field (background) - shallow
- Small aperture hole = Depth of field (background) - clear
- Big aperture hole = Depth of field (background) - shallow
- Small aperture hole = Depth of field (background) - clear
