Kodak UltraMax 400 ↗ Proposed base · unconfirmedBrand explicitly excludes motion-picture film. Independent lab identity discussion points toward Kodak/Ultramax but supplies no exact coating crosswalk. Vivid is not Vintage Tone or HARMAN Phoenix.
Relationship evidence
Still needed: Obtain a brand-issued exact product/coating crosswalk or inspect a documented, dated retail roll and base-stock control.
A solid connection establishes the stated relationship, such as a respool or family variant. It does not establish unchanged resolution, processing or coating generation. Dashed connections retain the identity uncertainty.
RESOLUTION ESTIMATES
Spatial Frequency & Equivalent MP
Results below use a 36 × 24 mm image area and ideal two-sample spatial sampling. Approximate graph readings retain their source process; a color-layer envelope is not an uncertainty interval.

Ikigai Film Lab Ilfocolor identity discussion ↗
Claims US/Kodak origin and reports edge-code indications, but explicitly allows nonidentical emulsions. No documented exact Vivid/Ultramax coating crosswalk or MTF test; used only as a lead, not identity proof.
Historical editions, coating revisions, development and retail batches retain their own scope. Research supplements do not change the main color-film catalog.
