Kodak Portra 800 ↗ Probable rebrandSpeed, formats, characteristic product attributes and distribution context support a Portra 800 rebrand inference. Checked Kodak launch/product pages do not declare exact chemical or coating-revision identity.

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.

Portra 160/400/800 speeds, formats and characteristic marketing attributes broadly correspond to Ektacolor Pro. This comparison supports an inference, not manufacturer-certified quantitative equivalence.
Historical editions, coating revisions, development and retail batches retain their own scope. Research supplements do not change the main color-film catalog.
