Lumenary is an exposure calculator designed for cinematographers, gaffers, camera assistants and film students.
Flip your light values between F-stop, T-stop, EV, lux, lumen and FC/foot candles. Convert readings from your light meter, determine T-stop on lenses without a proper T-stop scale, evaluate gear specification, photometrics and lighting needs.
Transform shutter angles to shutter speeds, adjust ISO and calibration constant - stay in control.
Add filters, modifiers, push/pull to your result to keep track of exposure!
