Q1 multiple-choice · color-stakes Why is color treated as data (not decoration) in medical photography?
Source: SPMED02 §1.
Q2 true-false · colorchecker-mandatory ColorChecker shot is required in every medical photography capture session.
Source: SPMED02 §2.
Explanation: Non-negotiable. Without ColorChecker, no color validation → no defensible color claim → audit risk.
Q3 multiple-choice · wb-discipline What’s the right WB discipline during medical capture?
Source: SPMED02 §4.
Explanation: Auto-WB drifts. Locked WB ensures consistency across all frames in a session.
Q4 scenario · color-space-fda FDA 510(k) submission, standard medical device, customer doesn’t specify color space.
Source: SPMED02 §3.
Q5 multiple-choice · archival-color-space What color space is recommended for archival masters (futureproofing)?
Source: SPMED02 §3.
Explanation: ProPhoto RGB encompasses most colors humans can perceive. Archive at the widest gamut; export to smaller per delivery.
Q6 multiple-choice · delta-e What’s the right Delta E tolerance for hero medical product photography?
Source: SPMED02 §7.
Explanation: Delta E is the color difference metric. < 2 for hero (Class III, premium); < 3 for routine submissions.
Q7 multiple-choice · chain-of-custody-steps How many steps in the forensic chain-of-custody for medical photography?
Source: SPMED02 §5.
Q8 scenario · metadata-gap Reviewing 6-month-old archived image finds metadata is incomplete (missing operator ID).
Source: SPMED02 §5.
Explanation: Audit-grade records require disciplined gap handling. Silent updates break integrity chain. Flag + escalate + document.
Q9 multiple-choice · colorchecker-handling Right handling of physical ColorChecker card?
Source: SPMED02 §2.
Explanation: Skin oils permanently affect patches; UV exposure fades; replace before degradation visible.
Q10 multiple-choice · validation-cadence Which validation cadence is the Specialist’s responsibility?
Source: SPMED02 §8.
Explanation: Layered validation. Per-session = ColorChecker. Weekly = sample QC. Monthly = card inspection. Quarterly = drift check. Annual = comprehensive.
Q11 true-false · auto-wb Auto-WB is acceptable for medical photography capture sessions.
Source: SPMED02 §4.
Explanation: Auto-WB drifts; locked WB after ColorChecker calibration is mandatory.
Q12 scenario · cri Customer’s existing lighting kit has CRI (color rendering index) rated 85.
Source: SPMED02 §2 (training notes Q&A).
Explanation: CRI < 95 limits achievable color accuracy. Medical photography wants high-CRI sources.
