Spectra: Atmospheric — Light Physics for Colorists
Time-of-day simulation built for JPLog2 and to complement the CMY-negative workflows
Atmospheric simulates the physics of natural light—sun angle, Rayleigh scattering, and ozone filtering—within your grading pipeline. It gives you full control over golden hour warmth, twilight blues, and mid-day clarity in a way that respects the integrity of your image.
For colorists working in scene-referred workflows, this tool introduces environmental realism without relying on LUTs or look hacks.
Key Features
• Simulates light angle, atmosphere, and spectral balance
• Modeled scattering and filtering based on time-of-day presets
• Adjustable warmth, ozone, and altitude for nuanced realism
• Designed for JPLog2 and to complement the CMY workflows, with no clipping or artifacts
Recommended Node Placement
Place after the IDT, and before the CMY Negative or a lens emulator.
Suggested Pipeline
IDT → Atmospheric → CMY Negative → Split Tone → RGB Reverter → CDL → LOOKDEV → SEC → TEXTURE → ODT
