Perspective

Definition

Relative apparent geometry determined by the viewpoint and scene. A relational image places a detail within recognisable scene context, complementing closer views. Photographic appearance alone is not a calibrated distance or position measurement.

Context

For example, a distant object can appear smaller than a nearer one without providing a direct measurement of their actual size difference.

Camera geometry, scale and appropriate methods are required for quantitative conclusions.
