Questions from this subtopic
Each one with the model answer underneath.
- 1
What should you establish first when interpreting a photograph?
Model answer
What it shows, where it was taken from and roughly when, because all three change what it is evidence of.
- 2
What is the difference between a vertical and an oblique aerial photograph?
Model answer
A vertical one looks straight down like a map, while an oblique one is taken at an angle and shows the sides of buildings and the horizon.
- 3
What can a ground-level photograph show that a satellite image cannot?
Model answer
Close detail such as the condition of buildings, street furniture and how people are using the space.
- 4
Why is a photograph limited as evidence?
Model answer
It captures one moment from one viewpoint, and whoever took it chose what to include and what to leave out.
- 5
What does annotating a photograph involve?
Model answer
Adding notes to particular features in the image that name them and explain why they matter.
- 6
What can a cartoon communicate that a photograph cannot?
Model answer
An opinion or argument, using exaggeration and symbols to make a point about an issue.
