Use the named Kodak sheet as a base-stock ECN-2 reference with its original test conditions; it is not a new measurement of a Flic retail roll or a C-41 result.

The title retains the document edition where identified. Research check dates are not publication dates. Consult the PDF for printed revision and process conditions.
Flic explicitly names the Kodak VISION3 base and ECN-2 process. The archived Kodak sheet is a base-stock reference; the Flic retail roll was not independently measured.
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.
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.
No product-specific spatial-resolution input is established here. You can explore a labeled base-stock scenario in the playground; it does not establish this retail film’s performance.
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.
Historical editions, coating revisions, development and retail batches retain their own scope. Research supplements do not change the main color-film catalog.
