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, saved lighting recipes, or the new Field Pack.
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
- Side-by-side recipe compare
- B&W filter factor calculator with Kelvin interpolation
- Hyperfocal, cine shutter, sunny f/16, macro, polarizer, and star-trail helpers
- Film reciprocity correction and AEB bracketing planner
- Field Pack with readiness scoring, support/gels/ND/bracket guidance, copyable shot brief, and ten offline reference sheets
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.
Quoi de neuf dans la dernière version ?
Version 2.1 adds Field Pack: a shot-brief planner with readiness scoring, ND/gels/bracket/support recommendations, copyable production notes, and ten high-resolution offline reference sheets for exposure, lighting ratios, Zone System placement, ND, gels and mired correction, cinema shutter angle, macro bellows, film reciprocity, location scouting, and keeper-frame prep.
Also includes updated screenshots and metadata to show the current app UI and Field Pack workflow.
