Dependencies
What this concept builds on and what it makes possible — derived from the atlas’s dependency, causal and structural relations, not from every related edge.
Foundations · builds on
Exposuredepends onApertureEstablished
Exposure depends on Aperture.
Mechanism: The aperture sets how much light passes per unit time, one of the three factors of exposure.
Exposuredepends onISO sensitivityEstablished
Exposure depends on ISO sensitivity.
Exposuredepends onShutter speedEstablished
Exposure depends on Shutter speed.
System context
Exposureis part ofRiskEstablished
exposure is part of risk.
Mechanism: Exposure is the link that turns a hazard into a risk.

Structural role & consequence
Interpreted from the current atlas graph — what the connections mean, not just how many there are.
Currently dark in the atlas: no key date stored · 7 of 7 of its relations lack claim-level evidence.
atlas representation · Describes the current Thinking OS representation, not the state of the world.
Builds on 3 foundations (requires / depends-on / derived-from / emerges-from).
structural · Structural graph analysis — not a claim of importance, causation or history.
Structural neighbourhood: 7 → 22 → 66 concepts reachable within 3 hops.
structural · Structural reach — being reachable is not the same as being understood.

Strengths & constraints
Constraints
- Evidence coverage currently thin in the atlas — few of its relationships carry claim-level evidence. atlas representation
- No dated history stored — the atlas records no key date for this concept. atlas representation
Conditions
- Its dependency reading rests on 3 foundation relations. structural
- Read structurally — most of its relationships carry no external evidence yet, so claims here are graph-derived. structural
Dependency radial
What this concept builds on (left) and what it makes possible (right) — derived from dependency and causal relations.
Seen through each discipline
How this concept sits in each of its fields — derived from its real connections in the graph, not asserted.
Exposure is studied in this field.
Through this lens it connects to Dynamic range, Aperture, ISO sensitivity and Lighting.
