Lumen Forge
iOS Universel / Photo et vidéo
Lumen Forge is a field exposure workbench for photographers, cinematographers, gaffers, students, and anyone who wants reliable light and exposure math close at hand.
Use the camera-based meter to read scene luminance and color temperature, then move directly into exposure planning, ND selection, flash guide-number math, zone-system notes, or saved lighting recipes.
Core tools:
- Live camera-based light meter
- Lux, foot-candle, EV, ISO, shutter, and aperture readouts
- Exposure triangle solver with equivalent exposure ladders
- Color-temperature reference swatches for common lighting conditions
- Zone-system histogram with shadow and highlight warnings
- ND filter calculator for daylight long-exposure planning
- Flash guide-number math with ISO scaling
- Lighting recipe notebook with modifier, subject, and location notes
- Hyperfocal, cine shutter, sunny f/16, macro, polarizer, and star-trail helpers
Lumen Forge keeps the workflow focused: meter the light, compare choices, save a useful note, and get back to shooting.
Lighting recipes and app settings stay on the device. Camera access is used only for the live meter and color-temperature features.
