Abyss Light Lab

Abyss Light Lab is a professional photography lighting calculator and studio photometer companion designed for photographers, cinematographers, and studio lighting technicians. It provides precision optical formulas and photometric calculations entirely offline without requiring user accounts or network access. - Exposure Value (EV) Engine: Calculate balanced exposure combinations across Shutter Speed, Aperture, and ISO with interactive dual-ring controls. - Color Temperature & Kelvin Converter: Analyze color spectrum shifts from 1000K to 12000K with exact Mired shift values and CTO/CTB corrective gel recommendations. - Lighting Contrast Ratio Simulator: Plan Key, Fill, and Rim lighting ratios from 1:1 up to 8:1 with visual portrait illumination modeling. - Photometric Illuminance Converter: Convert freely between Lux, Foot-Candles, Lumens, and Candela with standard reference benchmarks. - Inverse Square Law Falloff: Calculate light intensity loss across distances with visual decay curves for strobes and continuous lights. - Depth of Field & Hyperfocal Engine: Determine near limit, far limit, total depth of field, and hyperfocal distance across full-frame, APS-C, and medium format sensors. - Studio Blueprint Planner: Arrange light modifiers, softboxes, reflectors, and background lights on a top-down virtual studio grid. - Neutral Density (ND) Extender: Compute accurate long-exposure shutter speeds from ND2 up to ND100000 filters. - Strobe Guide Number Guide: Calculate flash output power steps from 1/1 to 1/128 relative to subject distance and lens aperture. - Time-Lapse Intervalometer: Estimate required shooting intervals, total frame captures, and storage footprint for timelapse productions. - Solar Angle & Golden Hour Guide: Determine offline solar elevation angles, shadow length multipliers, and blue hour windows. - Professional Studio Presets: Reference classic studio lighting diagrams including Rembrandt, Butterfly, Loop, Split, High-Key, and Noir setups. - Privacy & Offline Architecture: Operates 100% offline with zero runtime permissions and no third-party data tracking.
