The 10-criterion rubric

Each criterion is scored 0 to 5 and weighted. Weights sum to 100, so the total runs 0 to 500.
#CriterionWhat it measuresWeight

Tiers

Excellent 430+
Award-tier work. Holds up against the strongest portraiture you'd see in a major contest or feature.
Strong 380–429
Very good. Likely to land in a serious shortlist; one or two refinements from the top tier.
Solid 300–379
A real photograph with real virtues. Worth refining; identify your weakest criteria and reshoot or re-edit.
Below 300
Rough draft. Use the feedback to plan a stronger version: reshoot, recompose, or rethink the subject.

How the score works

For each criterion you get a 0–5 rating and a one-sentence rationale. Total = sum of (rating × weight). The breakdown matters more than the headline number — your three lowest-scored criteria are where to focus next.

About

Portrait Score is a single static HTML file. Open-source, no server, no tracking, no analytics. The rubric is general-purpose portraiture — informed by what consistently differentiates strong work in editorial, documentary, and contest contexts. It is opinionated, not neutral; treat the score as a structured second opinion, not a verdict.
