Micro level

Micro examples

Common questions

Why is the macro-to-micro sequence a standard scene documentation order?+

Recording the wide view first fixes the spatial relationship of items before they are approached or disturbed, so later micro-level examination can be tied back to where each item originally sat.

Can a single scene contain more than one micro-level focus?+

Yes. One macro scene, such as a room, can contain multiple micro subsets, for example the body, a weapon, and a point of entry, each documented and processed as its own focused unit.
