Physics Principle: Digital CMOS sensors record light linearly. 50% of all distinct digital tonal codes exist in the brightest 1 stop of exposure. Exposing to the Right (ETTR) maximizes photon count, crushing shadow noise without multi-frame temporal ghosting.

| Evaluation Metric | Single-Frame ETTR | Multi-Frame HDR Bracketing | Verdict Advantage |
|---|---|---|---|
| Temporal Ghosting | None (Single Shot) | High Risk (Edge Echoes) | Single-Frame ETTR Wins |
| Shadow SNR / Cleanliness | Pristine (+1.2 EV Boost) | Excellent (Multi-sample) | Comparable |
| Highlight Detail Retention | Preserved (92% capacity) | Preserved (-2 EV frame) | Tie |
| Tonal Contrast Naturalism | Photographic / Realistic | Prone to Haloes / Flatness | ETTR Natural Curve |
| Tripod Requirement | Handheld Viable (1/250s) | Mandatory Rigid Tripod | ETTR Field Agility |
