SELECTED FILM β BASE / FAMILY
Kodak UltraMax 400 β Base undisclosed400-specific official video rules out remjet removal and compares it to Aurora 800. Earlier CEO nondisclosure interview is specifically about 800; it cannot establish 400 as Ultramax.
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
Results below use a 36 Γ 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.
INSPECTABLE EVIDENCE
Still needed: Obtain a brand-issued exact product/coating crosswalk or inspect a documented, dated retail roll and base-stock control.
manufacturer page β’ CHECKED 2026-10-02
Directly fetched 2026-10-02. Current catalog confirms Elektra as Kodak Aerocolor IV and describes Apollo 18. Specific Chrome 100, Aurora 400 and Psychedelic 400 technical sheets were not located; the older URL now returns 404.
manufacturer page β’ CHECKED 2026-10-02
Current homepage/catalog checked alongside exact-product PDF searches. Linked UltraPan development-time charts concern black-and-white films.
manufacturer browser β’ CHECKED 2026-10-02
Browser shows Apollo 18 as 400-speed C-41 with 18 full-frame exposures; Chrome, Aurora and Psychedelic descriptions absent from this current catalog. Several unrelated black-and-white cards contain inconsistent Aerocolor template captions, so those captions cannot be extended to neighboring products. Product-specific Cine Color 50D/200T/250D/500T headings explicitly identify respooled Kodak VISION3 and ECN-2 processing; all four are marked no longer being produced. Elektra specifically names Kodak Aerocolor IV. These declarations do not extend to Aurora, Apollo 18, Chrome or Psychedelic.
manufacturer video β’ CHECKED 2026-10-02
Describes Aurora 400 as not remjet-removed film and similar to Aurora 800; does not disclose its exact base stock.
manufacturer video β’ CHECKED 2026-10-02
CEO says agreements prevent stock disclosure and describes native C-41 800-speed film. This statement concerns Aurora 800, not evidence of Aurora 400 emulsion identity.
Historical editions, coating revisions, development and retail batches retain their own scope. Research supplements do not change the main color-film catalog.
