Spectra: Bi-3-Strip — Classic Color, Two Ways
A 3-strip Technicolor-inspired gain stage with dual-mode logic
Inspired by the bold separation of early Technicolor, Spectra: Bi-3-Strip lets you subtly shift the density and weighting of red, green, and blue dye layers—independently. Built specifically for CMY Negative workflows, it honors the subtractive logic of dye transfer prints while offering a clever twist: Invert Mode, which flips the signal into additive RGB space, applies the gains, then reverts it—giving you two distinct tonal behaviors in one elegant tool.
Whether you’re emulating classic 3-strip color science or just nudging the balance of your primaries with surgical precision, Bi-3-Strip is a precision dye-shaping module that fits anywhere in your subtractive pipeline.
Key Features
• Independent gain control for R, G, and B channels
• Operates natively in CMY Negative space or via additive RGB path using Invert Mode
• Perceptually subtle ranges (±5%) to avoid overcorrection
• Neutral defaults for transparent pass-through
Recommended Node Placement
Use after CMY Negative and before contrast shaping for fine primary balancing, or as a final dye tweak before RGB reversion.
Suggested Pipeline
IDT → CMY Negative → Bi-3-Strip → Paper Contrast → Split Tone → RGB Reverter → CDL → LUT → ODT
