Photographs as geographical evidence
A photograph is a valuable geographical tool because it records the real appearance of a place at one moment in time. It shows physical features such as rivers and hills and human features such as roads, farms and buildings, helping us describe and explain the landscape.
Key idea
A landscape (ground) photograph is read in three zones: the foreground (nearest, at the bottom), the middle ground (centre) and the background (farthest, at the top).
Types of photographs
- Ground (landscape) photograph: taken from ground level, showing the front of features. Objects near the camera look larger.
- Oblique aerial photograph: taken from the air at an angle, showing the tops and sides of features and the horizon.
- Vertical aerial photograph: taken from directly above, showing only the tops of features, like a map view.
Example
In a beach photo, palm trees in the foreground appear large and detailed, while boats far out at sea in the background look small and hazy.
Interpreting a photograph
To interpret a photo, describe its location zones, identify physical and human features, and suggest the economic activity shown, such as fishing, farming or tourism. Clues to scale and distance include the size of known objects (people, cars) and the fact that features become smaller and less clear towards the background. A limitation of photographs is that they show only one view and moment, and cannot easily give direction or exact scale like a map.
Remember
- Foreground = nearest/bottom; background = farthest/top.
- Vertical aerial = view from directly above (map-like).
- Oblique aerial = angled air view showing the horizon.
- Photos show one moment and cannot give exact scale or direction.
