During excavation, which technique is used throughout the investigation to document the sequence of events?

Explanation:
Photographs provide a visual timeline of how the scene changes as excavation progresses. By taking systematic images at defined moments, from consistent angles, with scale and location notes, you create a series that shows the state of features, strata, and artifacts at each step. This visual record makes it possible to trace the sequence of discoveries and how relationships between objects and contexts evolve over time, which is essential for reconstructing what happened and when. While notes and sketches add detail and context and video can show action, photography offers an objective, repeatable record that remains accessible for review and analysis as the investigation unfolds.
