    Older Psychedelic/Street Candy product absent from current manufacturer catalog. NC500 claims remain unsupported here; same nominal speed and muted colors do not prove stock identity.

    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

Compare in playground β†’

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.

No product-specific spatial-resolution input is established here. ISO, visible grain and sensitometric curves cannot fill this gap.

INSPECTABLE EVIDENCE

Sources & Audit Trail

Historical editions, coating revisions, development and retail batches retain their own scope. Research supplements do not change the main color-film catalog.
