Kodak VISION3 500T ↗ Plausible base · code unconfirmedAHU/remjet-free tungsten film with EI 500 ECN-2 is consistent with current 500T technology, but RETO does not name Kodak/5219. AHU is a construction feature, not an exclusive manufacturer identity.
Proposed identification
Kodak VISION3 base; consistent with the recorded 500T candidate but exact current stock code remains undisclosed by RETO.
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.
