The warm bias was colour-timing and art direction, not the negative stock — practitioners describe the films as graded "a little on the warm side." Treat this as physically grounded, not archival.
ColourPush midtones/highlights warm-ochre — skies toward bone rather than blue, dust/skin toward #B98A4A. Not a flat overall tint.
BlacksLift slightly, never crush — dye-transfer prints paired high contrast with rich, still-readable shadow detail.
SaturationDesaturate 15–25% globally, except blood — keep it as the one saturated exception, per the palette variants above.
ContrastRaise moderately as a curve-shape decision — the dye-transfer path skipped a dupe generation, which is where the added contrast actually came from.
GrainOne size-step coarser than a default overlay — the real films doubled their base 50‑ASA grain via the Techniscope blow-up.
HalationWarm, tight halation on point highlights only — sun glints, metal, sweat. Never a hazy full-frame bloom.
Crop2.39:1, matching the post-1970 SMPTE anamorphic standard the modern restorations target.
