same distance and then recompose the photograph.

The focus area contains ob-
jects at diff erent distances
from the camera
Example: Subject is the same color as the back-
ground.
Example: Subject is inside a cage.
The subject is dominated by
regular geometric patterns
The focus area contains areas
of sharply contrasting bright-
ness
Example: A row of windows in a skyscraper. Example: Subject is half in the shade.
The subject appears smaller
than the focus area
The subject many contains
fi ne details
Example: Focus area contains both foreground
subject and distant buildings.
Example: A fi eld of fl owers or other subjects that
