EXPOCAL is the on-set exposure companion for cinematographers, DPs, and gaffers — every calculation you reach for between scouting a location and rolling, in one fast, dark-themed app. Nail exposure Incident metering math built on ISO 2720: dial in ISO/EI, shutter angle, and frame rate to get the exact T-stop — or work backwards from an aperture to the lux you need. Handles dual-base sensors and broadcast gain (dB) too. Match your gear Pick from a built-in library of 47 cinema cameras and 241 lenses. Check sensor coverage, mount compatibility, and how a lens, extender, or adapter behaves across your kit. Director's viewfinder Frame a shot right on your phone. Choose a camera and focal length and the live preview matches that lens's field of view — pinch or use the thumb zoom slider to find the frame before the camera is even built. Overlay mode draws the exact framing on a wide preview. Depth & focus Hyperfocal distance, depth of field, and aperture sweeps with sweet-spot, diffraction, and noise guidance. Light & color ND filter stops, white-balance mired shifts, and CTB/CTO/plus-green gel recommendations. Timecode Read SMPTE LTC straight from the audio input and show it full-screen, big enough to hold in front of a lens. When the sound has a clock and the camera does not, you film the number. The reader flywheels through dropouts and says when it has lost lock rather than pretending it hasn't. Export Generate clean PDF reports for scene and sensor planning. EXPOCAL gives estimates to support your judgment on set — always confirm critical exposures with your meter and monitor.

YOUR KIT · Tick the extenders and ND filters you actually own. Auto only ever suggests gear that's in the bag. · Choose extender, ND and adapter per lens instead of once for the whole kit, under an "All lenses" row everything else inherits from. · A lens with a built-in extender is offered its own factor, and a box lens takes its ND from the camera's wheel — because that's where it has to come from. BETTER ANSWERS · Variable-aperture zooms now say how far up the zoom a stop holds. · One Base ISO control replaces two checkboxes that cancelled each other out. · Cameras that can't reach the frame rate you set say so. · Frame rates up to 240, and shutter speeds include the cine values: 24 fps at 180° reads 1/48, not a rounded 1/50. · The target aperture list only offers stops your lenses actually have. FIXED · Corrected foot-candle handling in the Exposure tab. · The Scene tab now fits a phone screen.
