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.

Quello che in Home Assistant sta in dieci pagine diverse, qui sta dove lo cerchi: le luci, il clima, le tapparelle, le telecamere, i consumi, le persone. Una plancia sola, fatta per essere guardata. SI ABBINA CON UN QR CODE Si installa l'add-on gdahome in Home Assistant, si preme «Genera QR code» e lo si inquadra col telefono. Nessuna password da inserire, nessun token da copiare, nessuna porta da aprire sul router. I DATI DELLA CASA RESTANO IN CASA gdahome non ha un server che li raccolga e non ha un account da fare. Da fuori casa passa da un centralino che instrada e non legge: il filo è cifrato fra il telefono e la tua Home Assistant. IN AUTO, CON CARPLAY Il navigatore per auto elettriche (gdanav) è dentro l'app: percorso, soste di ricarica, colonnine, segnalazioni. E dietro il tasto con la casetta i comandi rapidi scelti da te: il cancello, il portone, «sto arrivando». Arrivando a casa, gdahome propone il comando dell'arrivo. E con Siri: «Ehi Siri, naviga con gdahome», «Portami a casa con gdahome». ANCHE - Il lucchetto col volto (Face ID) per aprire l'app. - Le segnalazioni e l'assistenza, dall'app. - Più case, e più plance per casa. Serve Home Assistant OS o Supervised (con il negozio degli add-on). gdahome Base è gratuita. gdahome Premium (abbonamento mensile o annuale) aggiunge più plance e più case, il collegamento da fuori casa, la configurazione e Zigbee dall'app, e comprende gdanav Premium.
